Hide Gridlines in Excel

Microsoft Excel's gridlines—those faint lines separating cells—are fundamental to spreadsheet navigation, but sometimes they detract from a clean, professional presentation. Whether you're preparing a financial report, creating a dashboard, or designing a printable form, knowing how to control gridline visibility is essential.

In this article, we’ll explore four practical and reliable ways to hide gridlines in Excel, covering on-screen viewing, printing, PDF export, and automated processing using C#. Each method serves a different purpose, allowing you to choose the approach that best fits your workflow.

Method Overview:

Method 1: Hide Gridlines in Excel View

The simplest way to hide gridlines is directly from Excel’s ribbon interface. This method affects only what you see on screen. It does not change how the worksheet prints or how it appears when exported to PDF.

Step-by-step Instructions

  1. Open your Excel worksheet.
  2. Go to the View tab on the ribbon.
  3. Go to view tab

  4. In the Show group, uncheck Gridlines.
  5. Uncheck gridlines

Once unchecked, gridlines immediately disappear from the worksheet view.

Important Note

Gridline visibility is configured per worksheet, not per workbook. If your file contains multiple sheets, you’ll need to repeat this action for each worksheet where gridlines should be hidden.

When to Use This Method

  • Cleaning up the workspace for better focus.
  • Preparing screenshots or screen recordings.
  • Reviewing dashboards or summary sheets.
  • Temporarily improving readability without affecting printed or exported output.

Method 2: Hide Gridlines When Printing an Excel Sheet

Excel treats printing gridlines separately from on-screen display. By default, gridlines don’t print, but if they appear in your printed output, you can disable them explicitly.

Standard Approach

  1. Open your Excel file.
  2. Switch to the Page Layout tab.
  3. Switch to page layout

  4. In the Sheet Options group, locate Gridlines.
  5. Locate gridlines section

  6. Uncheck the Print option.
  7. Uncheck print option

  8. Preview the result using File → Print .

This ensures gridlines won’t appear on paper or in print-based outputs.

Why This Matters

Printed Excel documents—such as invoices, reports, or forms—often require a polished, uncluttered look. Removing gridlines keeps the reader’s attention on the data itself, especially when borders, shading, or conditional formatting are already applied.

Pro Tip: Use Custom Views for Frequent Printing

If you frequently need to print without gridlines, consider creating a custom view:

  • Go to View → Workbook Views → Custom Views .
  • Click Add and name your view (for example, Print View).
  • Configure all print settings, including hiding gridlines.
  • Save the view and switch to it whenever needed.

Method 3: Hide Gridlines Before Exporting Excel to PDF

When exporting Excel to PDF, the output generally follows your print settings, which makes explicit configuration important.

Standard PDF Export Workflow

  1. Hide gridlines for printing (see Method 2).
  2. Go to File → Export → Create PDF/XPS Document .
  3. Go to export

  4. Specify the output file path and name, then click Publish .
  5. Click publish

When This Method is Essential

  • Sharing Excel data as PDF files.
  • Creating read-only or client-facing documents.
  • Archiving finalized reports.
  • Maintaining consistent formatting across platforms.

Key takeaway: Excel’s PDF export relies on print settings. If gridlines are enabled for printing, they will appear in the PDF—even if they’re hidden in the worksheet view.

Method 4: Hide Gridlines Programmatically Using C#

When dealing with multiple Excel files or automated workflows, manually adjusting gridline settings isn’t efficient. In such cases, C# .NET automation provides a scalable and reliable solution. Using Spire.XLS for .NET, you can disable gridlines programmatically before saving or exporting files.

Example: Hide Gridlines for Worksheet Viewing

using Spire.Xls;

namespace HideGridlines
{
    class Program
    {
        static void Main(string[] args)
        {
            // Load an Excel file
            Workbook workbook = new Workbook();
            workbook.LoadFromFile(@"E:\Files\Test.xlsx");

            // Get the first worksheet
            Worksheet worksheet = workbook.Worksheets[0];

            // Hide gridlines in the specified worksheet
            worksheet.GridLinesVisible = false;

            // Save the document
            workbook.SaveToFile("HideGridlines.xlsx", ExcelVersion.Version2016);
        }
    }
}

Example: Hide Gridlines for Printing and PDF Export

using Spire.Xls;

namespace DisableGridlines
{
    class Program
    {
        static void Main(string[] args)
        {
            // Load an Excel file
            Workbook workbook = new Workbook();
            workbook.LoadFromFile("Input.xlsx");

            // Get the first worksheet
            Worksheet worksheet = workbook.Worksheets[0];

            // Get the PageSetup object
            PageSetup pageSetup = worksheet.PageSetup;

            // Disable gridlines for printing or saving to PDF
            pageSetup.IsPrintGridlines = false;

            // Print the workbook
            workbook.PrintDocument.Print();

            // Save as PDF
            // worksheet.SaveToPdf("ToPDF.pdf");
        }
    }
}

When to Use This Method

  • Batch processing Excel files.
  • Automating Excel-to-PDF conversions.
  • Enforcing consistent formatting standards.
  • Integrating Excel operations into backend systems.

In addition to hiding gridlines, programmatic Excel processing allows developers to manage a range of formatting tasks through code, including adding or removing cell borders, applying conditional formatting rules, and standardizing worksheet layouts. These capabilities help create clean, consistent Excel workflows that scale reliably across multiple files and use cases.

Conclusion

Mastering gridline control in Excel enhances both the visual quality and professional presentation of your spreadsheets. While gridlines are helpful during data entry and analysis, hiding them at the right time can dramatically improve how your work is perceived.

  • Use View settings for quick, on-screen cleanup.
  • Rely on print options for physical documents and PDFs.
  • Choose .NET automation for scalable, repeatable workflows.

By applying the appropriate method for each scenario, you can ensure your Excel workbooks look exactly as intended—whether viewed on screen, printed on paper, or distributed as PDF files. Gridline control is a small detail, but one that makes a meaningful difference in professional Excel usage.

FAQs

Q1. Why are gridlines still visible after I hide them?

Gridlines may still appear if you only disabled them in View mode. To remove gridlines from printed or exported files, you must also disable them in print settings under the Page Layout tab.

Q2. Can I hide gridlines in one worksheet but keep them in others?

Yes. Gridline visibility is controlled per worksheet, not per workbook. You can hide gridlines on selected sheets while leaving others unchanged.

Q3. Will hiding gridlines remove cell borders?

No. Gridlines and cell borders are different. Hiding gridlines does not affect any manually applied borders, which will remain visible.

Q4. Do gridlines reappear when exporting Excel to PDF?

They can. Excel’s PDF export is based on print settings. If gridlines are enabled for printing, they will appear in the PDF even if they’re hidden in the worksheet view.

Q5. Can I hide gridlines in Excel using code?

Yes. Gridlines can be controlled programmatically. For C# workflows, libraries such as Spire.XLS for .NET allow you to disable gridlines before saving or exporting files.

Wrap Text in Excel

Have you ever printed an Excel report only to find your data cutting off mid-sentence or spilling into adjacent columns? This common formatting issue doesn't just look unprofessional—it compromises readability and can lead to misunderstandings of your data. Text wrapping is the essential solution, allowing content to stay neatly contained within a cell by breaking it into multiple lines.

Whether you're a casual user formatting a single spreadsheet or a data professional processing hundreds of files, different wrapping methods offer varying levels of efficiency. This guide provides five distinct approaches, from the simple one-click button to Python automation, giving you the right tool for every text-wrapping challenge you'll encounter in Excel.

Method overview:

Method 1: The Ribbon Button (The One-Click Wonder)

Best for: Everyday formatting tasks and quick adjustments

When you need immediate results without navigating through menus, Excel's ribbon button provides the fastest solution. Located prominently in the Home tab, this single click can transform chaotic data into organized content.

Step-by-Step Instructions:

  1. Select the cell(s), row, or column you want to format.
  2. Go to the Home tab on the ribbon.
  3. In the Alignment group, click the Wrap Text button (angled text with curved arrow).
  4. If text remains cut off, double-click below the row number to auto-fit the row height.

Pro Tip: Combine with the Format Painter (paintbrush icon) to quickly copy wrapping to other cells.

Method 2: The Format Cells Dialog Box (For Precise Control)

Best for: Comprehensive formatting sessions and alignment perfection

When you need more than just text wrapping—when you want to simultaneously control vertical alignment, text orientation, and other properties—the Format Cells dialog box offers complete control.

Step-by-Step Instructions:

  1. Select your target cells.
  2. Press Ctrl + 1 or right-click and choose Format Cells.
  3. Navigate to the Alignment tab.
  4. Under Text control, check the Wrap text checkbox.
  5. Set complementary options like vertical alignment, then click OK.
  6. Adjust the row height or auto-fit the row height.

Strategic Advantage: This method lets you establish a complete formatting profile in one operation, perfect for creating templates or standardized reports.

Method 3: Keyboard Shortcuts (For Speed Users)

Best for: Power users who prioritize efficiency and minimal mouse use

If you measure productivity in keystrokes saved, Excel's keyboard shortcuts will become your best friend. While there's no single-key shortcut for text wrapping, a simple three-key sequence accomplishes the task faster than any mouse-based method.

Step-by-Step Instructions:

  1. Select your target cells using keyboard navigation if preferred.
  2. Press and release Alt to activate ribbon keyboard navigation.
  3. Press H to select the Home tab.
  4. Press W to toggle Wrap Text on your selected cells.

Memory Aid: Think "Home, Wrap." With minimal practice, this sequence becomes muscle memory.

Method 4: Manual Line Breaks (For Exact Line Breaks)

Best for: Content where specific phrasing must remain together or break at logical points

Automatic text wrapping follows Excel's algorithms, but sometimes you need to decide exactly where lines break. For addresses, multi-part names, or lists within a single cell, manual control is indispensable.

Step-by-Step Instructions:

  1. Double-click the cell (or press F2) to enter edit mode.
  2. Click your cursor at the exact spot where you want the new line.
  3. Press Alt + Enter (Windows) or Option + Command + Enter (Mac).
  4. Press Enter to exit the cell.

Wrap text manually

Practical Application: Perfect for formatting addresses (123 Main Street on one line, Springfield, IL 62704 on the next) or creating within-cell lists.

Method 5: Python Scripts (For Bulk Processing & Automation)

Best for: Developers, data analysts, and anyone processing multiple files programmatically

When you graduate from individual spreadsheets to batch processing, manual methods hit their limits. Python with the Spire.XLS library transforms this tedious task into an automated, scalable solution.

pip install spire.xls
  1. Create a Python script with this core code:
from spire.xls import *
workbook = Workbook()
workbook.LoadFromFile("input.xlsx")
sheet = workbook.Worksheets[0]
sheet.Range["B3"].Style.WrapText = True# Wrap specific cell
workbook.SaveToFile("output.xlsx", ExcelVersion.Version2016)
workbook.Dispose()
  1. Customize the range (e.g., "A1:C10" for a block) and run the script.

Automation Advantage: Process dozens of files in seconds with 100% consistency. Add loops for multiple ranges or conditionals to wrap only cells meeting specific criteria.

Once you’ve mastered text wrapping with Spire.XLS, you can extend your automation further by programmatically autofitting rows and columns or applying conditional formatting rules to build polished, fully automated Excel reports.

Choose the Right Method

Selecting the right text wrapping approach depends on three factors: volume, frequency, and complexity.

Quick Decision Guide:

Scenario Recommended Method Time Estimate
Formatting 1-5 cells occasionally Method 1 (Ribbon) or Method 3 (Shortcut) 10-30 seconds
Creating templates with precise alignment Method 2 (Format Cells) 1-2 minutes
Entering addresses, lists, or structured content Method 4 (Manual Breaks) 30-60 seconds per cell
Processing 10+ files monthly Method 5 (Python) 2 hours initial setup, then seconds per file
Dynamic reports with variable content lengths Method 5 (Python) with conditional logic 3-4 hours setup, automated thereafter

FAQs

Q1: Why is my wrapped text still not fully visible after applying text wrapping?

A: This usually happens because the row height hasn't adjusted automatically. Simply double-click the boundary below the row number to auto-fit the row height. In some cases, you may need to manually drag the row border to make it taller.

Q2: Can I wrap text in multiple cells at once?

A: Absolutely. Select all the cells you want to format (by dragging, holding Ctrl for non-adjacent cells, or clicking the corner button to select the entire sheet), then apply any of the first four methods. For processing entire workbooks or multiple files, Method 5 (Python) is most efficient.

Q3: What's the difference between text wrapping and "Shrink to Fit"?

A: Text wrapping breaks long text into multiple lines within the same cell, increasing row height. "Shrink to Fit" (found in Format Cells > Alignment) reduces the font size to make the text fit in a single line without changing cell dimensions. Use wrapping when you want to maintain readability; use shrinking only for limited space situations.

Q4:Does text wrapping work with Excel Online or Google Sheets?

A: Yes, with slight variations. Excel Online has a Wrap Text button in its Home tab similar to desktop Excel. Google Sheets also has a text wrapping button (icon with angled text and arrow) in its toolbar. The Alt+Enter shortcut for manual breaks works in both platforms on Windows, and Python automation can be adapted for Google Sheets using the Google Sheets API.

Conclusion

From the simplicity of a single click to the power of Python automation, these five methods cover every text wrapping need you'll encounter in Excel. Each approach has its ideal use case—whether you’re making quick edits, perfecting a report's presentation, or processing data at scale. Mastering multiple methods ensures you're never stuck with overflowing cells again.

Remember that proper text formatting is more than cosmetic—it's fundamental to clear data communication. Start with the method that best fits your current task, and gradually expand your toolkit as your Excel needs evolve. With these techniques, you can ensure your spreadsheets always present information with maximum clarity and professionalism.

Spire.OfficeJS is a WebAssembly-based Office document editor that enables users to open, view, and edit Word, Excel, and PowerPoint documents directly in the browser. In this tutorial, we will walk through how to integrate Spire.OfficeJS into a Vue 3 application (Vue 3 + Vite), and build a fully client-side web application that supports online Office document editing—without relying on server-side document conversion.

By the end of this guide, you will have a runnable Vue project that allows users to upload Office documents and edit them directly in the browser using Spire.OfficeJS.

On this page:

What Is Spire.OfficeJS

Spire.OfficeJS is a web-based online Office document editing component that consists of four modules: Spire.WordJS, Spire.ExcelJS, Spire.PresentationJS, and Spire.PDFJS. It provides viewing and real-time editing capabilities for documents such as Word files, Excel spreadsheets, and PowerPoint presentations.

Spire.OfficeJS runs directly in the browser and can be deployed in any web project without installing plugins or relying on client-side software.

Key Features

  • Pure front-end rendering: Based on WebAssembly, allowing document editing without server-side conversion.
  • Rich editing capabilities: Supports document editing, comments, annotations, review, and saving.
  • Multi-format support: DOC, DOCX, XLS, XLSX, PPT, PPTX, PDF (view), and more.
  • High integrability: Can be flexibly embedded into Vue, React, Angular, or pure HTML projects.
  • High customizability: Supports toolbar configuration, user permissions, save callbacks, plugin extensions, and more.

Spire.OfficeJS is suitable for enterprise systems, document management systems (DMS), collaboration platforms, online learning systems, and form-based applications.

How Spire.OfficeJS Works

Spire.OfficeJS is built on WebAssembly-based Office rendering engines that execute directly in the browser. The simplified workflow is:

  1. A user uploads an Office document via the browser.
  2. The file is read as binary data (Uint8Array).
  3. The binary data is passed directly to the WebAssembly runtime.
  4. The document is parsed, rendered, and edited client-side.
  5. Save actions trigger callbacks for custom persistence logic.

Unlike traditional server-based Office editors, no server-side document conversion or rendering is required, significantly reducing infrastructure complexity and latency.

Preparation

Install Node.js

Download and install Node.js 22.12.0 or later from the official Node.js website. Node.js 22+ is recommended to ensure compatibility with Vite, modern ES module tooling, and WebAssembly-related workflows.

Verify the installation:

node -v
npm -v

Verify installation

Create a Vue 3 Project

Step 1: Create a project folder

Create a new folder to store the project files.

Step 2: Enter the folder via Command Line

cd /d d:\demo

Enter folder

Step 3: Initialize a Vue 3 project

npm init vue@latest

Initialize vue project

Rename the project to vue-spire and skip optional features to create a minimal Vue 3 project.

Step 4: Start the development server

cd vue-spire
npm run dev

Start development server

Integrating Spire.OfficeJS

Step 1: Download the product package

Download Spire.OfficeJS product package from our website. After extracting the package, you will find a web folder containing the editor’s static assets and WebAssembly files.

Download Spire.OfficeJS

Step 2: Copy static resources to the Public directory

In your Vue project:

  • Open the project in VS Code.
  • Create a folder: public/spire.cloud .
  • Copy the entire web folder into it. This allows the editor resources to be accessed via /spire.cloud/web/....

Copy web folder

Step 3: Install required dependencies

Install Pinia and Vue Router manually to keep the project setup explicit and easy to follow.

npm install pinia
npm install vue-router@4

Install dependencies

Step 4: Create the project structure

Create the following structure under src :

src/
├── router/
│   ├── index.js
├── stores/
│   ├── file.js
├── views/
│   ├── FileUpload.vue
│   └── Spire.OfficeJS.vue

Create project structure

Step 5: Setup application

  1. main.js — Application initialization
  2. This file initializes the Vue application and registers Pinia and Vue Router. Pinia is used to manage shared document data, while Vue Router controls page navigation between the file upload view and the document editor view.

    import { createApp } from 'vue'
    // Import Pinia
    import { createPinia } from 'pinia'
    import App from './App.vue'
    import router from './router'
    
    const app = createApp(App)
    
    // Create Pinia instance
    const pinia = createPinia()
    
    // Register Pinia and Router to the Vue application
    app.use(pinia)
    app.use(router)
    app.mount('#app')
    
  3. App.vue — Root component
  4. App.vue serves as the root container of the application. It renders different pages dynamically using RouterView, allowing the file upload page and the document editor to be loaded as separate routes without reloading the application.

    <script setup>
    import { RouterView } from 'vue-router'
    </script>
    
    <template>
        <RouterView/>
    </template>
    
  5. Router index.js — Page navigation
  6. The router defines the navigation flow of the application. The root route (/) is used for file upload, while /document loads the Spire.OfficeJS editor. This separation allows users to upload a document first and then open it in the editor with shared state preserved.

    import { createRouter, createWebHistory } from 'vue-router'
    import FileUpload from '../views/FileUpload.vue'
    import SpireOfficeJs from '../views/Spire.OfficeJS.vue'
    
    const router = createRouter({
        history: createWebHistory(),
        routes: [
            {
                path: '/',
                name: 'upload',
                component: FileUpload
            },
            {
                path: '/document',
                name: 'document',
                component: SpireOfficeJs
            },
            {
                path: '/:pathMatch(.*)*',
                redirect: '/'
            }
        ]
    })
    
  7. Pinia Store (file.js) — File state management
  8. The Pinia store is responsible for sharing file metadata and binary data between different views. The uploaded file is converted into a Uint8Array and stored here so that it can be passed directly to Spire.OfficeJS in serverless mode.

    import { ref } from 'vue'
    // Import defineStore from Pinia to define a state management store
    import { defineStore } from 'pinia'
    
    // Define a file state management store
    export const useFileStore = defineStore('file', () => {
      // Store the uploaded file object (File type)
      let file = ref(null)
      // Store the file binary data (Uint8Array format) for editor loading
      let fileUint8Data = ref(null);
    
      // Set the file object
      function setFileData(data) {
        file.value = data;
      }
      // Set the file binary data
      function setFileUint8Data(data) {
        fileUint8Data.value = data;
      }
      // Export state and methods for component usage
      return { file, fileUint8Data, setFileData, setFileUint8Data }
    })
    
  9. FileUpload.vue — File upload page
  10. FileUpload.vue is responsible for handling user-selected Office documents before they are passed to the editor. It reads the uploaded file using the browser File API and converts it into a Uint8Array, which is required by Spire.OfficeJS in serverless mode.

    <template>
        <main>
            <button @click="btnClick">Choose Your File</button>
            <label>
                <input id="input" type="file" @change="handleFileChange" style="display: none;" />
            </label>
        </main>
    </template>
    
    <script setup>
    import { useRouter } from 'vue-router'
    import { useFileStore } from '../stores/file'
    
    // Router instance: redirect to /document after successful upload
    const router = useRouter()
    // Pinia Store: store the user-uploaded file and binary data
    const fileStore = useFileStore()
    
    // Handle file upload
    async function handleFileChange(event) {
        // Get the file selected by the user through the input change event
        const selectedFile = event.target.files?.[0]
        if (!selectedFile) {
            return
        }
    
        // Save the original File object and binary data for the editor to read
        fileStore.setFileData(selectedFile)
        const buffer = await selectedFile.arrayBuffer()
        fileStore.setFileUint8Data(new Uint8Array(buffer))
    
        // Redirect to the document editing page after successful upload
        router.push('/document')
    }
    function btnClick() {
        var btn = document.querySelector('#input');
        btn.click()
    }
    </script>
    
  11. Spire.OfficeJs.vue — Online editor integration

Spire.OfficeJs.vue is the core integration component where the Spire.OfficeJS editor is initialized and rendered. It dynamically loads the Spire.OfficeJS runtime, configures editor behavior, and passes the document binary data to the WebAssembly engine using serverless mode.

<template>
    <div class="form">
        <div id="iframeEditor">
        </div>
    </div>
</template>

<script setup>
import { ref, onMounted, onUnmounted } from 'vue';
import { storeToRefs } from 'pinia';
import { useFileStore } from '../stores/file.js'
import { useRouter } from 'vue-router';

const fileStore = useFileStore()
// Data stored in Pinia
const { file, fileUint8Data } = storeToRefs(fileStore)
const router = useRouter()
const config = ref({});
const isOpened = ref(false);
const editorInstance = ref(null);
const apiInstance = ref(null);
const originUrl = window.location.origin

onMounted(() => {
    // Redirect back to upload page if no file exists
    if (!file.value) {
        router.replace('/');
        return;
    }
    // Load editor script dynamically
    loadScript();
    window.addEventListener('resize', OnWindowReSize);
})

onUnmounted(() => {
    window.removeEventListener('resize', OnWindowReSize);
})

// Initialize the configuration object required by the editor
function initConfig() {
    if (!file.value) {
        throw new Error('File not found, please upload again');
    }

    if (!fileUint8Data.value) {
        throw new Error('File data not found, please upload again');
    }

    config.value = {
        "fileAttrs": {
            "fileInfo": {
                "name": file.value.name,
                "ext": getFileExtension(),

            },
            "sourceUrl": originUrl + "/files/__ffff_192.168.2.134/" + file.value.name,
            "createUrl": originUrl + "/open",
            "mergeFolderUrl": "",
            "fileChoiceUrl": "",
            "templates": {}

        },
        "user": {
            "id": "uid-1",
            "name": "Jonn",

            "editorWidth": "100%",
            "editorHeight": "100%",
            "editorType": "document",
            "platform": "desktop", // desktop / mobile / embedded
            "viewLanguage": "en", // en / zh
            "isReadOnly": false,
            "canChat": true,
            "canComment": true,

FAQs

Q1. Why does the editor load a blank page?

This usually occurs when static resource paths are incorrect or required WebAssembly files are missing. Ensure the web directory is correctly placed under public/spire.cloud and that SpireCloudEditor.js is accessible.

Q2. Why doesn’t the document open after uploading?

The editor requires the file to be passed as a Uint8Array. Verify that the file data is correctly read, stored in Pinia, and assigned to serverless.fileData.

Q3. Can Spire.OfficeJS run without a backend server?

Yes. When serverless.useServerless is enabled, all document loading, rendering, and editing are performed entirely in the browser using WebAssembly.

Q4. Which file formats are supported by Spire.OfficeJS?

Spire.OfficeJS supports Word (.doc, .docx), Excel (.xls, .xlsx), PowerPoint (.ppt, .pptx), and PDF (.pdf) files.

Q5. How can I save the edited document?

Use the onSave event to capture the edited document data and implement custom logic to upload, store, or download the file.

Conclusion

By following this tutorial, you have successfully integrated Spire.OfficeJS into a Vue 3 application and built a fully client-side Office document editor powered by WebAssembly. This approach eliminates server-side document conversion while providing a rich, responsive editing experience directly in the browser.

Add Notes to PowerPoint

Adding notes to your PowerPoint slides is a simple yet powerful way to enhance your presentations. Whether you are preparing for a live talk, creating teaching materials, or sharing slides with colleagues, speaker notes help you stay organized, remember key points, and deliver your message with confidence.

In this article, we will cover two practical ways to add notes to PowerPoint: manually using PowerPoint Desktop and programmatically using Python with Spire.Presentation.

What Are PowerPoint Notes?

Speaker notes are additional text linked to each slide that only the presenter can see during a presentation. They help you:

  • Remember key points without cluttering the slides
  • Provide handouts with extra details
  • Collaborate with teammates by adding comments or instructions

Notes complement slide content rather than duplicate it, keeping your presentation clear and engaging.

Method 1: Add Notes Using PowerPoint Desktop

The most common way to add notes is manually in PowerPoint Desktop. This method is intuitive, beginner-friendly, and works for both Windows and Mac users.

Step-by-Step Guide

  1. Open your presentation in PowerPoint Desktop.

  2. Switch to Normal View if it isn’t already enabled. You can do this from the View tab or the bottom-right icons.

    Switch to Normal View

  3. At the bottom of each slide, you will see a Notes pane. If the pane is hidden, click Notes at the bottom of the window to reveal it.

    See Notes Pane

  4. Click inside the Notes pane and type your speaker notes. You can include bullet points, short paragraphs, or reminders.

    Add Notes inside Notes Pane

  5. Save your presentation once you finish adding notes.

Tips and Best Practices

  • Keep notes concise: Avoid writing full paragraphs. Focus on key points and cues.
  • Use bullet points: Helps you scan notes quickly during a presentation.
  • Align with slide content: Make sure notes correspond to the slide visuals for smoother delivery.
  • Formatting: You can apply basic formatting such as bold, italics, or font size adjustments to emphasize important points.

Advantages

  • Works offline, no additional tools needed.
  • Allows full formatting flexibility for notes.
  • Beginner-friendly and widely supported across all PowerPoint versions.

Optional Tip

During presentations, you can use Presenter View (Alt + F5) to view these notes privately while your audience sees only the slides. This feature is invaluable when presenting in live settings or online meetings.

Method 2: Add Notes Programmatically Using Python

For developers, educators, or enterprises working with multiple presentations, adding notes manually can be time-consuming. Using Python with Spire.Presentation allows you to automate the addition of speaker notes to one or more slides, saving time and maintaining consistency.

Why Automate Notes?

  • Bulk updates: Quickly add or modify notes across many slides or presentations.
  • Consistency: Standardize notes format, style, and bullet points.
  • Integration: Works with other Python workflows, such as data processing or automated report generation.

Step-by-Step Guide

Below is an example Python workflow using Spire.Presentation:

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation object
ppt = Presentation()

# Load an existing PowerPoint presentation
ppt.LoadFromFile("input.pptx")

# Get the first slide
slide = ppt.Slides[0]

# Add a notes slide
notesSlide = slide.AddNotesSlide()

# Add paragraphs to the notes slide
paragraph = TextParagraph()
paragraph.Text = "Summary Slide:"
paragraph.FirstTextRange.IsBold = TriState.TTrue
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph)

paragraph = TextParagraph()
paragraph.Text = "Recap the three main points"
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph)

paragraph = TextParagraph()
paragraph.Text = "Reinforce the core message"
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph)

paragraph = TextParagraph()
paragraph.Text = "Prepare for the conclusion"
notesSlide.NotesTextFrame.Paragraphs.Append(paragraph)

# Apply numbering style to specific paragraphs
for i in range(2, notesSlide.NotesTextFrame.Paragraphs.Count):
    notesSlide.NotesTextFrame.Paragraphs[i].BulletType = TextBulletType.Numbered
    notesSlide.NotesTextFrame.Paragraphs[i].BulletStyle = NumberedBulletStyle.BulletArabicPeriod

# Save the resulting presentation
ppt.SaveToFile("AddSpeakerNotes.pptx", FileFormat.Pptx2016)
ppt.Dispose()

Output:

Add Notes to PowerPoint Using Python

Explanation of the Code

  1. Load Presentation: ppt.LoadFromFile("input.pptx") opens an existing PowerPoint file.
  2. Access Slide: slide = ppt.Slides[0] retrieves the first slide.
  3. Add Notes Slide: slide.AddNotesSlide() creates a dedicated notes area for the slide.
  4. Add Paragraphs: Each TextParagraph object is added to the NotesTextFrame.
  5. Format Bullets: Numbered bullet style is applied to all paragraphs except the first one.
  6. Save File: ppt.SaveToFile() saves the updated presentation with the new notes.

Delete Blank Pages in PDF

Blank pages are a common issue in PDF documents. They often appear when exporting files from Word or Excel, scanning paper documents, or generating reports programmatically. Although blank pages may seem harmless, they can negatively affect document quality, increase file size, waste printing resources, and make documents look unprofessional.

Depending on your situation, removing blank pages from a PDF can be done either manually or automatically. Manual methods are suitable for small documents and one-time tasks, while automated solutions are more efficient for batch processing, recurring workflows, or system-level integrations.

In this article, we’ll explore both approaches in detail. First, we’ll walk through three manual methods for deleting blank pages from PDFs. Then, we’ll demonstrate how to automatically detect and remove blank pages using Python, with a complete and practical solution based on Spire.PDF for Python.

What Is a “Blank Page” in a PDF?

A “blank page” in a PDF is not always truly empty from a technical standpoint. While it may look blank visually, it can still contain invisible objects, empty containers, or white images.

In practice, a blank PDF page may:

  • Contain no text objects
  • Contain no images
  • Appear visually blank but still include invisible elements
  • Include layout artifacts created during conversion

This distinction is especially important when automating the removal process, as simple text-based checks are often insufficient.

Part 1: Manually Delete Blank Pages from a PDF

Manual methods are best suited for small files where accuracy and visual confirmation are important. They require no programming knowledge and allow users to selectively remove pages after reviewing the document.

Method 1: Delete Blank Pages Using Adobe Acrobat

Adobe Acrobat provides a professional and highly accurate way to manage PDF pages. Its thumbnail-based interface allows users to visually inspect all pages and remove blank ones precisely.

Steps

  1. Open the PDF file in Adobe Acrobat.

  2. Open Page Thumbnails panel.

    Open Page Thumbnails Panel

  3. Select the blank page you want to remove, then click the “Trash” icon.

    Click trash icon Alternatively, right-click the selected page and choose “Delete Pages…” , which allows you to delete the current page or a range of consecutive pages.

    Choose Delete Pages

  4. Save the updated PDF.

Pros

  • High accuracy with visual confirmation.
  • Handles complex layouts and large PDFs well.

macOS includes a built-in application called Preview, which supports basic PDF editing features such as page deletion. It’s a simple and free option for macOS users.

Steps

  1. Open the PDF file with Preview.

  2. Enable the thumbnail sidebar by selecting View → Thumbnails.

    View thumbnails in Preview

  3. Select the blank pages in the thumbnail panel.

    Select Blank Pages in Preview

  4. Press the Delete key.

  5. Save the modified PDF.

Pros

  • Free and pre-installed on macOS.
  • Offline and easy to use.
  • No third-party tools required.

Cons

  • macOS-only solution.
  • Manual process that doesn’t scale.
  • Limited advanced PDF features.

When Manual Methods Are Not Enough

Manual methods become inefficient when:

  • Processing many PDF files.
  • Cleaning automatically generated reports.
  • Performing recurring document maintenance.
  • Integrating PDF cleanup into applications or services.

In these scenarios, automation is the most practical and reliable approach.

Part 2: Automatically Delete Blank Pages in PDF Using Python

Automation allows you to remove blank pages consistently and efficiently without human intervention. Python is particularly well-suited for this task due to its simplicity, cross-platform support, and extensive library ecosystem.

Why Use Python for PDF Automation?

With Python, you can:

  • Process PDFs programmatically.
  • Handle large files and batch operations.
  • Integrate PDF cleanup into backend systems.
  • Ensure consistent detection logic across documents.

Automation significantly reduces manual effort and minimizes the risk of human error.

Introduction to Spire.PDF for Python

Spire.PDF for Python is a robust library for creating, editing, and processing PDF documents. It provides fine-grained control over PDF structure and content, making it ideal for tasks such as blank page detection and removal.

For this solution, Spire.PDF offers:

  • Page-level access
  • Built-in blank page detection
  • PDF-to-image conversion
  • Safe page removal

Python Code: Automatically Detect and Remove Blank Pages from PDF

Below is a complete Python example using Spire.PDF for Python and Pillow (PIL).

import io
from spire.pdf import PdfDocument
from PIL import Image

# Custom function: Check if the image is blank (all pixels are white)
def is_blank_image(image):
    # Convert the image to RGB mode
    img = image.convert("RGB")
    # Define a white pixel
    white_pixel = (255, 255, 255)
    # Check whether all pixels are white
    return all(pixel == white_pixel for pixel in img.getdata())

# Load the PDF document
doc = PdfDocument()
doc.LoadFromFile("Input.pdf")

# Iterate through pages in reverse order
# This avoids index shifting issues when deleting pages
for i in range(doc.Pages.Count - 1, -1, -1):
    page = doc.Pages[i]

    # First check: built-in blank page detection
    if page.IsBlank():
        doc.Pages.RemoveAt(i)
    else:
        # Second check: convert the page to an image
        with doc.SaveAsImage(i) as image_data:
            image_bytes = image_data.ToArray()
            pil_image = Image.open(io.BytesIO(image_bytes))

            # Check whether the image is visually blank
            if is_blank_image(pil_image):
                doc.Pages.RemoveAt(i)

# Save the cleaned PDF file
doc.SaveToFile("RemoveBlankPages.pdf")
doc.Close()

How Blank Page Detection Works in This Solution

To improve accuracy, this approach uses two complementary detection methods:

  1. Logical detection: The script first checks whether a page is logically empty using page.IsBlank(). This detects pages with no text or image objects.

  2. Visual detection: If a page is not logically blank, it is converted to an image and analyzed pixel by pixel. If all pixels are white, the page is considered visually blank.

This combined strategy ensures that both technically empty pages and visually blank pages with hidden content are removed.

Extending the Automation Solution

This script can be easily extended to:

  • Process all PDFs in a directory
  • Run as a scheduled cleanup task
  • Integrate into document management systems
  • Log removed pages for auditing or debugging

With minor adjustments, it can support enterprise-scale PDF workflows. For more advanced PDF operations, refer to the Spire.PDF Programming Guide to further expand and customize your automation logic.

Manual vs Automated Blank Page Removal

Aspect Manual Methods Python Automation
Ease of use High Medium
Accuracy High High
Batch processing x
Scalability x
Best use case Small PDFs Large or recurring tasks

Best Practices for Removing Blank Pages from PDFs

  • Always keep a backup of original files.
  • Test detection logic on sample documents.
  • Be cautious with scanned PDFs.
  • Combine automation with manual review for critical files.

Final Thoughts

Removing blank pages from PDFs is a small but important step toward producing clean, professional documents. Manual methods work well for quick edits and small files, but they don’t scale efficiently.

For larger or recurring tasks, automation is the clear solution. By using Spire.PDF for Python and combining logical and visual detection techniques, you can reliably remove both technically and visually blank pages. This approach saves time, improves consistency, and integrates seamlessly into modern document workflows.

FAQs

Q1: Why do blank or unwanted pages appear in PDF files?

Blank or extra pages often appear due to formatting issues during document conversion, incorrect page breaks, scanning artifacts, or exporting files from Word, Excel, or reporting tools.

Q2: Can I delete pages from a PDF without using paid software?

Yes. You can delete pages using free options such as built-in tools like macOS Preview, online PDF editors, or free desktop PDF readers that support basic page management.

Q3: Will deleting pages affect the content or layout of the remaining PDF?

Deleting pages does not change the layout or formatting of the remaining pages. However, it’s recommended to review the final document to ensure page numbering, bookmarks, or references still make sense.

Q4: Is it safe to delete pages from a PDF?

Yes, as long as you keep a backup of the original file. Deleting pages is a non-destructive operation when saved as a new file, making it easy to restore the original if needed.

How to Add Watermarks to Excel (4 Easy Ways)

Add Watermarks to Excel

Watermarks are widely used in Excel files to indicate document status or ownership, such as Confidential, Draft, Sample, or a company logo. They are especially useful when sharing reports internally or distributing files to external stakeholders.

Unlike Microsoft Word, Excel does not provide a dedicated “Watermark” feature. However, there are several practical ways to achieve the same effect using built-in tools or programmatic solutions.

In this article, you’ll learn four easy and effective ways to add watermarks to Excel, ranging from manual techniques to automated watermarking using Python.

Method overview:

Method 1: Add a Watermark Using Header & Footer

Using the Header & Footer feature is the most widely accepted way to add a watermark in Excel, particularly for documents that will be printed or exported as PDFs.

Because the watermark is placed outside the worksheet grid, it does not interfere with cell content while remaining consistent across pages.

This method works well for adding logos or “draft” images to formal reports and official documents.

Steps

  1. Open your Excel file.

  2. Go to Insert → Header & Footer.

    Go to insert header and footer

  3. Click the center section of the header.

    Click center section

  4. Click Picture under Header & Footer section to insert an image watermark, or type text directly.

    Click Picture under header and footer section

    Note: An image watermark is recommended, as header text often makes it difficult to achieve an effective watermark appearance.

  5. Tap anywhere outside the header to see the watermark.

    See header image watermark

Pros

  • Printable.
  • Clean and professional appearance.
  • Suitable for logos and document labels.

Cons

  • Not visible in Normal view.
  • Limited formatting flexibility.

Best Use Case

This method is best suited for formal or shareable Excel documents where the watermark needs to appear in print, Print Preview, or exported PDFs without interfering with worksheet data.

Method 2: Insert a Background Image as a Watermark

Excel allows you to insert an image as a worksheet background, which can serve as a watermark. This watermark remains visible in Normal view, making it useful for on-screen review, internal sharing, or template files.

However, background images are designed purely for visual reference and will not appear when printing or exporting to PDF.

Steps

  1. Open your Excel file.

  2. Go to Page Layout → Background.

    Go to page layout

  3. Select an image file.

    Select an image file

  4. The image will repeat across the worksheet.

    Go to page layout

Pros

  • Visible in Normal view.
  • Simple to apply.
  • Applies to the entire worksheet.

Cons

  • Not printable.
  • Limited customization.

Best Use Case

This method is best suited for internal documents or working templates where visibility during editing is more important than print output.

Method 3: Insert WordArt or Shapes as a Watermark

Inserting a WordArt, Text Box, or Shape provides the most control over a watermark’s appearance.

Because the watermark is a regular worksheet object, it remains visible in Normal view and can be freely resized, rotated, and styled.

This approach is ideal when you need custom text-based watermarks or different watermark styles on individual sheets.

Steps

  1. Go to Insert → WordArt.

    Insert WordArt

  2. Select a predefined style from the drop-down menu.

    Select a predefined style

  3. Enter the watermark text (for example, “CONFIDENTIAL”).

    Enter confidential

  4. Rotate the shape and adjust the appearance (size, color, or style) of text as needed.

    Adjust appearance of WordArt

Pros

  • Fully customizable.
  • Visible in Normal view.
  • Easy to edit or remove.

Cons

  • May move when rows or columns are resized.
  • Requires manual setup per worksheet.

Best Use Case

This method is best suited for on-screen review scenarios where the watermark must remain visible in Normal view and where flexible text styling or sheet-specific labeling is required.

Method 4: Add Watermarks to Excel Programmatically Using Python

When watermarking needs to be applied repeatedly or across multiple files, programmatic automation is the most efficient approach.

Using Spire.XLS for Python, you can add watermarks programmatically in the same ways as the manual methods described earlier, including header/footer watermarks, background image watermarks, and shape-based watermarks.

This ensures consistent results while reducing manual effort, especially in report generation or document distribution workflows.

Example: Add an Image Watermark via Header & Footer

The following example adds an image watermark to the center header of every worksheet. This method is equivalent to Method 1 and produces a watermark that appears in Page Layout view, Print Preview, and exported PDFs.

from spire.xls import *
from spire.xls.common import *

# Create a Workbook object
workbook = Workbook()

# Load an Excel document
workbook.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.xlsx")

# Load the watermark image
stream = Stream("C:\\Users\\Administrator\\Desktop\\confidential.png")

# Apply the watermark to all worksheets
for i in range(workbook.Worksheets.Count):
    worksheet = workbook.Worksheets[i]
    worksheet.PageSetup.CenterHeader = "&G"
    worksheet.PageSetup.CenterHeaderImage = stream

# Save the result
workbook.SaveToFile("output/AddWatermark.xlsx", ExcelVersion.Version2016)

# Release resources
workbook.Dispose()

Typical Use Cases

  • You need to watermark multiple Excel files or worksheets.
  • Watermarks must be applied consistently and automatically.
  • Excel files are generated as part of a reporting or export pipeline.

To explore additional Excel automation capabilities and API usage details, see the Spire.XLS Programming Guide. The guide covers practical examples that can help you extend watermarking logic and build more flexible Excel processing solutions.

Add stamps to PDF

Adding stamps to a PDF is a common task in document review, approval, and distribution workflows. Stamps are often used to mark files as Approved, Draft, or Confidential, or to apply visual elements such as company logos and official seals.

In practice, PDF stamps are usually added either manually through desktop software or programmatically as part of an automated workflow. While many tools can place text or images on a PDF, only a few create stamps that remain movable and editable when the document is reopened in PDF editors such as Adobe Acrobat.

This article introduces two reliable and widely used approaches for adding stamps to PDF files:

  • Adobe Acrobat, which is well-suited for manual and visual editing
  • Python (Spire.PDF) , which is ideal for automation and batch processing

Each method demonstrates how to add both text stamps and image stamps, helping you choose the best approach for your workflow.

What Is a PDF Stamp?

A PDF stamp is implemented as a Rubber Stamp Annotation, defined in the PDF specification. Compared with ordinary text or images, stamps:

  • Can be moved freely in Adobe Acrobat.
  • Appear in the Comments / Stamps panel.
  • Can be reused across documents.
  • Are clearly identified as annotations, not page content.

This distinction is critical when documents are reviewed, revised, or audited later.

Method 1: Add Text and Image Stamps Using Adobe Acrobat

Adobe Acrobat offers built-in support for PDF stamping and is one of the most commonly used tools for manual, visual document review and approval. It allows you to add both text-based and image-based stamps and adjust their appearance directly on the page.

Add a Text Stamp in Adobe Acrobat

Adobe Acrobat includes several predefined text stamps—such as Approved, Draft, and Confidential—and also lets you create and customize your own stamps.

Steps:

  1. Open the PDF in Adobe Acrobat.

  2. Go to Tools → Stamp .

    Go to tools then find stamp

  3. Select a built-in text stamp.

    Select a built-in stamp

  4. Click anywhere on the page to place the stamp.

    Select a built-in stamp

  5. Resize or reposition the stamp as needed.

  6. Right-click the stamp and choose Properties to further customize its appearance (such as color and opacity) and stamp details like the author or subject.

    Choose properties to further customize the stamp

  7. Save the document.

Once added, the stamp remains movable and editable, making it easy to adjust placement or update its properties later.

Add an Image Stamp in Adobe Acrobat

Image stamps are typically used for company logos, official seals, or scanned signatures. Acrobat allows you to convert image files into reusable custom stamps.

Steps:

  1. Prepare an image file in PNG or JPG format.

  2. In Acrobat, navigate to Tools → Stamp → Custom Stamps → Create .

    Create a custom stamp

  3. Import the image and save it as a custom stamp.

    Import an image file

  4. Assign the stamp to a selected category for easier reuse.

    Assign the stamp to a category

  5. Open the Stamp tool or Stamps palette, select the newly created stamp, and click to place it on the page.

    Choose the custom stamp

  6. Adjust the stamp’s size and position visually.

  7. Save the document.

Image stamps created this way behave the same as text stamps—they can be moved, reused across documents, and managed directly within Acrobat.

Pros and Limitations of Adobe Acrobat

Advantages

  • Comprehensive support for text and image stamps.
  • Precise visual control over placement and appearance.
  • Well-suited for one-off edits and small document sets.

Limitations

  • Fully manual workflow.
  • Not designed for batch processing or automation.

Method 2: Add Text and Image Stamps Using Python (Spire.PDF)

For developers and automated workflows, adding stamps programmatically is often the most efficient and scalable solution. Instead of manually placing stamps on each document, you can define the stamp’s appearance once and apply it consistently across one or many PDF files.

Spire.PDF for Python provides APIs for creating and applying stamp annotations directly, giving you precise control over layout, styling, and positioning. This approach is particularly useful for:

  • Batch processing large numbers of PDF files.
  • Automated approval or review workflows.
  • Backend or server-side document generation.

Add a Text Stamp to a PDF Using Python

The following example demonstrates how to create a custom text stamp with a styled background and apply it to a specific page. The stamp content, fonts, colors, and placement can all be adjusted programmatically.

from spire.pdf import *
from spire.pdf.common import *

# Load the PDF document
doc = PdfDocument()
doc.LoadFromFile(r"C:\Users\Administrator\Desktop\input.pdf")

# Get the target page (zero-based index)
page = doc.Pages.get_Item(1)

# Create a template for the stamp
w, h, r = 220.0, 50.0, 10.0
template = PdfTemplate(w, h, True)
bounds = template.GetBounds()

# Fonts and brush
title_font = PdfTrueTypeFont("Elephant", 16.0, 0, True)
info_font = PdfTrueTypeFont("Times New Roman", 10.0, 0, True)
brush = PdfSolidBrush(PdfRGBColor(Color.get_Blue()))
linearGradientBrush = PdfLinearGradientBrush(
    bounds, 
    PdfRGBColor(Color.get_White()), 
    PdfRGBColor(Color.get_LightBlue()), 
    PdfLinearGradientMode.Horizontal)

# Draw the stamp background
path = PdfPath()
path.AddArc(bounds.X, bounds.Y, r, r, 180.0, 90.0)
path.AddArc(bounds.X + w - r, bounds.Y, r, r, 270.0, 90.0)
path.AddArc(bounds.X + w - r, bounds.Y + h - r, r, r, 0.0, 90.0)
path.AddArc(bounds.X, bounds.Y + h - r, r, r, 90.0, 90.0)
path.AddLine(bounds.X, bounds.Y + h - r, bounds.X, bounds.Y + r / 2)
template.Graphics.DrawPath(PdfPen(brush), path)
template.Graphics.DrawPath(linearGradientBrush, path)

# Draw text
template.Graphics.DrawString("APPROVED", title_font, brush, PointF(5.0, 5.0))
template.Graphics.DrawString(
f"By Manager at {DateTime.get_Now().ToString('HH:mm, MMM dd, yyyy')}",
    info_font, brush, PointF(5.0, 28.0)
)

# Create and apply the stamp
rect = RectangleF(50.0, 500.0, w, h)
stamp = PdfRubberStampAnnotation(rect)
appearance = PdfAppearance(stamp)
appearance.Normal = template
stamp.Appearance = appearance
page.AnnotationsWidget.Add(stamp)

# Save the result
doc.SaveToFile("output/TextStamp.pdf", FileFormat.PDF)
doc.Dispose()

When the output file is opened in Adobe Acrobat, the stamp can be moved, resized, and managed just like a stamp added manually.

Add a text stamp to PDF using Python

Add an Image Stamp to a PDF Using Python

Image stamps are commonly used for logos, seals, or visual approval marks. The process is similar to text stamping, but the template is built from an image instead of drawn graphics.

from spire.pdf import *
from spire.pdf.common import *

# Load the PDF document
doc = PdfDocument()
doc.LoadFromFile(r"C:\Users\Administrator\Desktop\input.pdf")

# Get the target page
page = doc.Pages.get_Item(1)

# Load the image
image = PdfImage.FromFile(r"C:\Users\Administrator\Desktop\approved-stamp.png")
w, h = float(image.Width), float(image.Height)

# Create a template and draw the image
template = PdfTemplate(w, h, True)
template.Graphics.DrawImage(image, 0.0, 0.0, w, h)

# Define the stamp position
rect = RectangleF(50.0, 500.0, w, h)

# Create and apply the image stamp
stamp = PdfRubberStampAnnotation(rect)
appearance = PdfAppearance(stamp)
appearance.Normal = template
stamp.Appearance = appearance
page.AnnotationsWidget.Add(stamp)

# Save and close
doc.SaveToFile("output/ImageStamp.pdf", FileFormat.PDF)
doc.Dispose()

The image stamp can be repositioned or resized in Adobe Acrobat and behaves consistently with stamps created through the Acrobat interface.

Add a custom image stamp to PDF using Python

When to Choose Python Over Adobe Acrobat

A Python-based approach is the better option when:

  • The same stamp must be applied to multiple PDF files.
  • Stamp content needs to be generated dynamically (for example, dates, user names, or status values).
  • PDF processing is part of an automated or backend workflow.

Adobe Acrobat is ideal for visual, one-off edits, while Python excels when stamping needs to scale.

To explore more advanced PDF processing scenarios, you can also refer to other Spire.PDF programming resources, such as tutorials on adding headers and footers, watermarking PDF pages, or annotating and signing documents programmatically. These topics can help you extend your PDF workflows further.

Feature Comparison

Feature Adobe Acrobat Python (Spire.PDF)
Text stamps Yes Yes
Image stamps Yes Yes
Rubber Stamp Annotation Yes Yes
Movable in Acrobat Yes Yes
Batch processing No Yes
Automation No Yes

Final Thoughts

Adding stamps to a PDF can be handled in different ways depending on how often you work with documents and how much control you need.

  • Adobe Acrobat is a solid choice for manual tasks where visual accuracy matters. It works well for occasional stamping, reviews, and approvals that require direct interaction with the document.
  • Python with Spire.PDF is better suited for automated workflows. It allows you to apply text and image stamps programmatically, making it ideal for batch processing or integrating stamping into existing systems.

Both approaches support common stamping needs, including status labels and image-based marks such as logos or seals. By choosing the method that fits your workflow, you can keep PDF stamping efficient, consistent, and easy to manage.

FAQs

Q1. What’s the difference between adding text or images and adding a stamp annotation?

Text or images are usually added as fixed page content. Stamp annotations are interactive elements that can be moved, resized, and managed in PDF editors like Adobe Acrobat.

Q2. Why aren’t stamps from some PDF tools editable in Adobe Acrobat?

Many tools flatten content onto the page instead of creating annotations. Flattened content becomes static and can’t be repositioned or reused as a stamp.

Q3. Can stamps added with Python be edited in Adobe Acrobat later?

Yes. When a stamp annotation is created programmatically, it behaves the same as one added in Acrobat and remains fully editable.

Q4. When should I use programmatic stamping instead of a PDF editor?

Use programmatic stamping for automation, batch processing, or dynamic content. PDF editors are better for quick, manual edits.

  7. Save the modified PDF to a new file.

Example Code

from spire.pdf.common import *
from spire.pdf import *

# Create a PdfDocument object
doc = PdfDocument()

# Load a PDF file
doc.LoadFromFile("Input.pdf")

# Create font, brush and pen
font = PdfTrueTypeFont("Times New Roman", 12.0, PdfFontStyle.Regular, True)
brush = PdfBrushes.get_Black()
pen = PdfPen(brush, 1.0)

# Specify the blank margins around the page
leftMargin = 54.0
rightMargin = 54.0
bottomMargin = 72.0

# Create a PdfPageNumberField object and a PdfPageCountField object
pageNumberField = PdfPageNumberField()
pageCountField = PdfPageCountField()

# Create a PdfCompositeField object to combine page count field and page number field in a single field
compositeField = PdfCompositeField(font, brush, "Page {0} of {1}", [pageNumberField, pageCountField])

# Iterate through the pages in the document
for i in range(doc.Pages.Count):

    # Get a specific page
    page = doc.Pages[i]

    # Get the page size
    pageSize = doc.Pages[i].Size

    # Measure the size the "Page X of Y"
    pageNumberSize = font.MeasureString("Page {} of {}".format(i + 1, doc.Pages.Count))

    # Set the location of the composite field
    compositeField.Location = PointF((pageSize.Width - pageNumberSize.Width)/2,
                                     pageSize.Height - bottomMargin + 18.0)

    # Draw the composite field on the page
    compositeField.Draw(page.Canvas, 0.0, 0.0)

# Save to a different PDF file
doc.SaveToFile("PageNumbers.pdf")
doc.Dispose()

This script inserts “Page X of Y” at the bottom center of each page. If you want to explore more layouts—such as left-aligned or right-aligned page numbers—refer to the full guide: Add Page Numbers to a PDF Document in Python.

Pros

  • Full control over number placement.
  • Great for batch processing.
  • Works even for scanned PDFs.

Cons

  • Requires basic coding knowledge.

Tips for Best Results

  1. Choose the right position for minimal interference
  2. If your PDF has headers, footers, or dense content near the margins, place page numbers in a corner or away from key elements. Bottom-right and bottom-left positions typically offer the least disruption while still remaining visible.

  3. Use a clear and informative numbering style
  4. Formats like “Page X of Y” provide readers with clear navigation, especially in long documents. If you only need simple numbering, stick with plain digits for a cleaner look.

  5. Match the document’s typography
  6. Consistency improves professionalism. Try to match the page-number font with the document’s existing typeface, size, and color. This ensures the page numbers blend naturally with the rest of the PDF layout.

  7. Leave adequate margin space
  8. If your PDF is text-heavy or uses footers, ensure there’s enough bottom margin so the page numbers don’t overlap content. Adjust spacing as needed based on preview results.

  9. Avoid adding numbers to certain pages

Some documents—such as cover pages, table of contents, or section dividers—look cleaner without page numbers. Exclude these pages if your tool allows custom page ranges.

Compare the Different Methods

Method Difficulty Cost Best For Limitations
Adobe Acrobat Easy Paid Professional, accurate results Requires subscription
Online Tools Very easy Free Quick tasks, no installation Privacy concerns, file size limits
Microsoft Word Easy Free with Word Text-based PDFs Layout distortion possible

Highlight Duplicates in Excel: 4 Easy Methods

Highlight Duplicates in Excel

Duplicate values are a common issue in Excel spreadsheets. Whether you’re working with customer lists, product inventories, invoices, or survey results, duplicate data can lead to errors, inaccurate reports, and poor decisions.

Fortunately, Excel provides several simple and effective ways to highlight duplicates so you can easily spot and manage them. In this article, you’ll learn four easy methods to find and highlight duplicate values in Excel—from built-in tools to automated solutions using Python.

Method overview:

Method 1: Conditional Formatting (Built-in – Easiest Way)

This is the fastest and most beginner-friendly way to highlight duplicates in Excel. It uses Excel’s built-in visual rules, so no formulas or technical skills are required. With just a few clicks, Excel automatically scans your selected range and marks duplicate values. This method is ideal for quick checks and small to medium-sized datasets.

Steps

  1. Select the cell range you want to check (for example, B2:B11).

    select cell range

  2. Go to Home → Conditional Formatting.

    go to conditional formatting

  3. Click Highlight Cells Rules → Duplicate Values.

    set highlight cell rules

  4. Choose a formatting style (fill color, text color).

    choose a formatting style

  5. Click OK.

Excel will instantly highlight all duplicate values in the selected range.

Key Benefits

  • Best for quick, visual checks
  • No formulas required

Method 2: Use a Formula with Conditional Formatting

This method lets you define exactly how Excel identifies duplicates, such as highlighting only repeated values or excluding the first occurrence. It requires a basic understanding of formulas but gives you much greater flexibility than built-in rules. This approach works especially well for structured or complex datasets.

Example Formula

To highlight all duplicate values (including the first occurrence):

=COUNTIF($B$2:$B$11,B2)>1

What this formula means:

  • COUNTIF($B$2:$B$11, B2) counts how many times the value in cell B2 appears in the range B2:B11.
  • If the count is greater than 1, Excel treats the value as a duplicate.

In simple terms, this formula tells Excel to highlight any cell whose value appears more than once in the selected range. The dollar signs ($) lock the search range so it stays fixed when the rule is applied to other cells.

For more COUNTIF examples, see Microsoft’s official documentation.

Steps

  1. Select your data range.

  2. Go to Conditional Formatting → New Rule.

    set new rule

  3. Select Use a formula to determine which cells to format.

    use a formal to determine which cells to format

  4. Enter the formula above.

    enter a formula

  5. Choose a format and click OK.

    choose a format

This method is useful when you want to customize how Excel treats duplicates.

Key Benefits

  • More flexibility
  • Works well with complex datasets

Method 3: Use a Helper Column with COUNTIF

This method relies on a helper column to count how many times each value appears in your dataset. It provides a clear, transparent view of duplicates that is easy to audit and validate. Because the results update automatically, it is ideal for dynamic worksheets that change frequently. This approach works well when accuracy and traceability are important.

Steps

  1. In a blank column (for example, F2), enter:

    =COUNTIF($B:$B,B2)
    

    enter countif in a blank column

  2. Then drag the formula down.

    drag the formula down

How It Works

  • A result of 1 means the value is unique.
  • A result greater than 1 means it’s a duplicate.

You can then apply conditional formatting to the helper column to visually highlight duplicates.

Key Benefits

  • Great for dynamic, updatable reports
  • Easy to audit and track duplicates

Method 4: Use Python with Spire.XLS for Automation

If you frequently work with large Excel files or repetitive tasks, you can use Python with Spire.XLS for automation. This method allows you to programmatically scan and highlight duplicates without manual effort. It helps save time, reduce human error, and process files in bulk. This approach is ideal for developers or teams that need scalable Excel solutions.

What Is Spire.XLS for Python?

Spire.XLS for Python is a powerful library that allows you to read, write, format, and manipulate Excel files using Python—no Microsoft Excel installation required.

Installation

pip install spire.xls

Sample Code to Highlight Duplicates

from spire.xls import *
from spire.xls.common import *

# Load the Excel file
workbook = Workbook()
