How to Convert Markdown to HTML: 3 Easy Ways

Step-by-Step Visual Guide to Convert Markdown to HTML

Markdown has become a popular choice for creating online documentation, blog posts, and README files due to its simplicity and readability. However, when it comes to displaying content on websites or within HTML-based applications, converting Markdown to HTML is essential.

In this guide, we'll show you three simple and effective methods to convert Markdown to HTML: using desktop applications, leveraging free online tools, and automating the process with Python for batch conversions. Let's get started!

What You Will Learn

What is Markdown?

Markdown is a lightweight markup language that allows you to write structured text using simple syntax. It's easy to read and write, and doesn't require complicated HTML tags. Markdown documents are often used in platforms like GitHub, Stack Overflow, and blogs. While it's perfect for creating content, the web can't directly interpret Markdown.

Common uses of Markdown:

  • Blog posts
  • Documentation
  • Readme files for GitHub repositories
  • Books and eBooks

Why Convert Markdown to HTML?

Transforming Markdown into HTML is essential for web compatibility and content management. Here's why:

  • Web Compatibility: HTML is universally supported by all web browsers, ensuring your content is accessible, while Markdown is not natively rendered by browsers.
  • Better Formatting and Styling: HTML provides robust options for styling and layout, making it ideal for creating rich, visually appealing content.
  • Cross-Device Support: HTML adapts seamlessly across platforms-desktops, tablets, and mobile devices-ensuring your content looks great everywhere.
  • Integration with Web Tools: Most content management systems (CMS), blogs, and web applications require HTML for content formatting, as it integrates better than Markdown in these environments.
  • SEO Optimization: With HTML, you can use key SEO elements like headings, meta tags, and links, which improve content discoverability and search engine rankings.

Best Practices and Troubleshooting for Converting Markdown to HTML

When converting Markdown to HTML, following best practices and addressing common issues are essential for a smooth and efficient process. Below, we highlight key practices and solutions to common challenges during conversion.

Best Practices

  • Use a Reliable Tool

    Choose a reputable converter or editor that handles Markdown syntax correctly and generates clean, valid HTML.

  • Preview the Output

    Always preview the HTML before finalizing the conversion. This allows you to identify any formatting discrepancies between the original Markdown and the converted HTML.

  • Check Cross-Browser Compatibility

    After conversion, test the HTML in multiple browsers (e.g., Chrome, Firefox, Safari) to ensure that it displays correctly across different platforms.

  • Clean the HTML Code

    Review the outputted HTML for unnecessary or redundant code. A clean and well-structured HTML file improves performance, ease of maintenance, and SEO.

  • Use Semantic HTML

    Ensure the HTML output includes appropriate semantic tags (e.g., <header>, <section>, <article>) to improve accessibility and SEO.

Troubleshooting Common Issues

  • Images Not Converting Properly

    Ensure that image paths are relative and hosted online. Local image paths may not render correctly when shared or uploaded. Use online image links or relative paths to resolve this issue.

  • Code Blocks Losing Formatting

    To maintain code block formatting and syntax highlighting, use triple backticks along with the appropriate language specification. This ensures that code appears correctly in the converted HTML.

  • Tables Not Rendering Correctly

    Double-check the Markdown table syntax to ensure it is properly structured. Make sure rows and columns are aligned using pipes (|) and dashes (-). Incorrect syntax can cause tables to render incorrectly in the HTML output.

Conclusion

Converting Markdown to HTML is a straightforward process that can be done through various methods, depending on your needs. For most casual users who need one-time conversions, desktop apps like Typora and VSCode, or online Markdown to HTML converters like Dillinger, are ideal. However, if you need to batch process a large number of Markdown files, Python automation can save you considerable time and effort.

Select the method that best fits your workflow and start converting your Markdown files into HTML documents that are ready for web publication.

Step 3: Configure the Filter

In the pop-up window:

  • Select the Copy to another location button.
  • The List range should already be populated with your data range.
  • Leave the Criteria range blank.
  • Click in the Copy to box, then select a cell where you want the unique list to be copied (e.g., $A$13).
  • Crucially, check the box for "Unique records only".

Configure the Excel Advanced Filter to copy unique records

Step 4: Execute and Confirm

Click OK. Excel will copy all unique rows from your original data range to the new location you specified. You can now compare this unique list with your original data.

Find and Remove Duplicates in Excel Using a Conditional Formatting Helper Column

If you prefer not to delete anything immediately but instead want to identify and highlight duplicates for manual review, this method is perfect. It allows you to mark duplicates with a formula, then filter and delete them as needed.

Best for: Carefully reviewing and manually removing duplicates without permanent deletion right away.

Step-by-Step Instructions:

Step 1: Add a Helper Column

Insert a new column to the right of your data and give it a descriptive header like "Is Duplicate?". This column will be used to mark duplicate entries for easy identification.

Add-a-Helper-Column.png

Step 2: Enter the Formula

In the first cell of the new column, enter the following formula. Make sure to adjust the ranges to fit your data:

=COUNTIFS($A$2:$A2, A2, $B$2:$B2, B2, $C$2:$C2, C2, $D$2:$D2, D2) > 1

Enter the formula for duplicate checking in Excel

This is a "running count" formula that checks how many times the current row's combination of values (from columns A, B, C and D) has appeared so far. If the count is greater than 1, it will return TRUE, indicating a duplicate.

Note: A more modern alternative is the UNIQUE function in Excel 365, but this COUNTIFS method works in all versions of Excel.

Step 3: Copy the Formula Down

To apply the formula to the rest of the rows, double-click the fill handle (the small square at the bottom-right of the cell). This will copy the formula down the entire column, marking all duplicates.

Copy the Formula Down the Entire Column

Step 4: Filter and Delete

  • Apply a filter to your data by selecting your header row and clicking Data > Filter.

    Apply a filter to your data

  • Filter the "Is Duplicate?" column to show only TRUE values. This will display all duplicate rows (keeping the first instance).

  • Select all visible rows, right-click, and choose Delete Row to remove the duplicates.

    Delete duplicate rows from the Excel sheet

  • Clear the filter to view your clean, unique list of data.

Remove Duplicate Data in Excel Using Power Query

For those who work with data regularly, Power Query (also known as Get & Transform) is a game-changer. It's a non-destructive and fully reversible process, allowing you to clean data without permanently altering the original. Plus, Power Query can be refreshed with a single click if your source data changes, making it ideal for ongoing data management.

Best for: Cleaning regularly updated data and creating a repeatable data-cleaning process.

Step-by-Step Instructions:

Step 1: Load Your Data into Power Query

  • Select your data range.

  • Go to the Data tab, and click on From Table in the Get & Transform group.

    Click on the From Table button in Excel

  • In the dialog box, ensure the My table has headers box is checked, then click OK. This will open the Power Query Editor window, where you can clean and transform your data.

Step 2: Remove Duplicates

In the Power Query Editor, you can remove duplicates based on selected columns:

  • Select the columns you want to base the duplicate check on. Hold Ctrl to select multiple columns.

  • Right-click on one of the selected column headers and choose Remove Duplicates from the context menu.

    • Tip: To remove duplicates based on the entire row, select all the columns before clicking Remove Duplicates.

    Remove duplicates by selected columns in Excel using Power Query

Step 3: Close and Load

Once your duplicates are removed, click Close & Load from the Home tab. Power Query will create a new worksheet with your cleaned, duplicate-free data.

Eliminate Duplicates with the UNIQUE Function in Excel 365

If you have Microsoft 365, you have access to the revolutionary dynamic array functions. The UNIQUE function is the simplest way to extract a list of unique values in Excel without altering the original data.

Best for: Instantly extracting a unique list that updates dynamically.

Eliminate Duplicates with the UNIQUE Function in Excel 365

Step-by-Step Instructions:

Step 1: Select a Single Cell

Click on an empty cell where you want the unique list to appear. This will be the starting point where the unique values will "spill" into.

Step 2: Enter the UNIQUE Formula

In the selected cell, enter the following formula:

=UNIQUE(A2:D10)

This assumes your data is in the range A2:D10. Modify the range according to your dataset.

Step 3: Press Enter

Once you've entered the formula, simply press Enter. Excel will automatically spill the entire list of unique rows into the cells below. This new list is dynamic. If you change data in your original range, the unique list will update automatically.

For more details on the UNIQUE Function, see the official Microsoft documentation: UNIQUE function.

Visual Guide for Removing a Table in Excel

Removing a table in Excel is a simple yet essential task for simplifying your data. While tables are useful for organizing and managing information, there are times when you might want to remove them - whether to streamline formatting, export raw data, or stop using structured features.

In this guide, we'll explore various methods to remove a table in Excel, including converting it to a range, clearing its formatting, and deleting it completely. Additionally, we'll demonstrate how to automate the process using VBA and Python, helping you save time when working with multiple tables.

Contents Overview

Understanding What Happens When You Remove a Table in Excel

Removing a table in Excel can have different outcomes depending on the method you choose:

  • Convert to Range: Keeps all your data and any table-applied formatting as static cell formatting, but removes table features like filters and structured references.
  • Clear Table Formatting: Keeps data but removes all table colors, borders, and styles.
  • Delete Entire Table: Permanently removes both the table and its data.

Let's explore these options in detail and see how they affect your Excel data.

How to Remove a Table in Excel by Converting It to a Range?

The simplest and most reliable method for removing a table in Excel is to convert it to a regular range, which keeps your data and formatting intact. You can choose from two main options for this conversion: using the Excel ribbon or the Right-Click menu.

Option 1. Using the Excel Ribbon

Follow the steps below to convert a table to a range through the Excel ribbon:

  • Select Any Cell Inside Your Table: Click on any cell (such as "A1") within the table you wish to remove. You don't need to select the entire table.

    Select Any Cell Inside Your Table

  • Navigate to the Design Tab: As soon as you select a table cell, the contextual Design tab will appear on the Excel ribbon, under Table Tools. Click on it.

    Navigate to the Design Tab

  • Click "Convert to Range": In the Tools group on the far left, you will find the "Convert to Range" button. Click it.

    Click Convert to Range

  • Confirm the Action: Excel will pop up a dialog box asking, "Do you want to convert the table to a normal range?" Click Yes.

    Confirm the Action

After conversion, the table structure is removed, and filters are no longer available. However, any table formatting (like banded rows and header styles) remains, but the range becomes static instead of dynamic.

Option 2. Using the Right-Click Menu

For those who prefer context menus, using the Right-Click menu is just as effective and a bit faster:

  • Select Any Cell Inside the Table: Just like in the first method, click anywhere inside your table's data.

  • Right-Click to Open the Context Menu: Right-click on the selected cell.

  • Navigate the Menu: In the right-click menu, hover over (or click) Table.

  • Select "Convert to Range": From the sub-menu that appears, select Convert to Range.

    Convert Table to Range in Excel using the Right-Click menu

  • Confirm the Action: Click Yes in the confirmation dialog box.

This method produces the same result as using the ribbon but offers a quicker, mouse-driven approach.

How to Remove Table Formatting in Excel?

In some cases, you might want to remove the table formatting in Excel, including elements like filters, colors, and borders. Follow the steps below to clear the formatting and return your data to a simpler layout:

  • Convert the Table to a Range: First, convert the table to a normal range using either the Excel ribbon or the right-click menu described above.

  • Clear the Table Formatting
    Now, the data is a simple range, you can remove the leftover formatting.

    • Select the Entire Data Range: Click and drag to select all the cells that were part of the original table, including the header.

    • Go to the Home Tab: On the Excel ribbon, navigate to the Home tab.

      Go to the Home Tab

    • Clear the Formats:

      • In the Editing group, click on the Clear button (it looks like a pink eraser).

        Click on the Clear button

      • From the dropdown menu, select Clear Formats.

        Select Clear Formats

Now, all table-specific formatting is removed, but your data remains intact. The cells revert to Excel's default font, color, and borders, giving you a clean, unformatted block of data ready for new formatting or analysis.

How to Remove a Table in Excel Completely

If you need to remove both the table and all the data it contains, this method will help. Make sure you're certain you no longer need the information before proceeding. To completely delete a table, follow these steps:

  • Select the Entire Table: Click anywhere inside the table and press Ctrl + A (Windows) or Cmd + A (Mac) to select the entire table, including the header and total rows.

  • Clear All Data and Formatting: Go to the Home tab and find the Editing group. Click Clear, then select Clear All from the dropdown menu.

This action permanently removes all data, formatting, and the table structure. The cells will be cleared, leaving no trace of the original table.

  • Copy and paste the following VBA code:

    Sub ConvertAllTablesToRanges()
      Dim ws As Worksheet
      Dim tbl As ListObject
    
      For Each ws In ActiveWorkbook.Worksheets
          For Each tbl In ws.ListObjects
              tbl.Unlist  ' Convert table to range
          Next tbl
      Next ws
    End Sub
    
  • Press F5 to run the macro.

This macro loops through every worksheet in the Excel file, finds all ListObjects (tables), and converts them into normal ranges - preserving the data but removing table functionality.

For more details on the Unlist method used in this VBA script, see the official Microsoft documentation: Excel ListObject.Unlist Method.

In this guide, you will learn 4 easy ways to remove hyperlinks in Excel - manually through the right-click menu or the Home tab, and automatically using VBA macros or C# - so you can clean your sheets efficiently, keep your data organized, and maintain a professional-looking workbook.

Table of Contents

How to Remove Hyperlinks Manually in Excel?

If you only have a few hyperlinks to delete, manual removal is usually the quickest solution. Excel provides built-in tools for this task, and they're easy to access. Below are three different manual methods you can use, depending on your preference and situation.

Remove Hyperlinks using the Right-Click Menu

This is the most direct and beginner-friendly way to remove hyperlinks from an Excel sheet, especially when dealing with a small dataset.

Steps to Remove Hyperlinks in Excel using the Right-Click Menu:

  • Open your Excel file in MS Excel, and then select the cell or range that contains the hyperlinks you want to remove.

Select the Cell or Range to Remove Hyperlinks

  • Right-click on the selected cell or range.
  • From the context menu, choose Remove Hyperlinks.

Right-click Menu Option to Remove Hyperlinks in Excel

Excel instantly removes the hyperlink but keeps the display text intact. The text remains visible in the cell, only without the clickable link.

Delete Hyperlinks using the Right-Click Menu - Output

Tip: If you select a single cell, the menu will show Remove Hyperlink. If you select multiple cells, Excel changes it to Remove Hyperlinks, allowing you to delete all hyperlinks in one go.

Remove Hyperlinks using the Home Tab

Another quick way to remove hyperlinks in Excel is through the Home tab on the ribbon. This method works similarly to the right-click option but is better for those who prefer working with Excel's toolbar rather than context menus.

Steps to Remove Hyperlinks from Excel using the Home Tab:

  • Select the cell or range that contains the hyperlinks you want to delete.

Select Cells to Remove Hyperlinks

  • Go to the Home tab on the top toolbar, next to Insert.

Go to Home Tab in Excel to Remove Hyperlinks

  • In the Editing group on the right, click the Clear button (the one with the pink eraser icon). A drop-down list will appear.

Click the Clear Button in Excel Home Tab to Remove Hyperlinks

  • From the list, choose Clear Hyperlinks or Remove Hyperlinks based on your needs:

    • Clear Hyperlinks - Removes only the hyperlink, while keeping the original text formatting intact.

    • Remove Hyperlinks - Deletes both the hyperlink and any formatting (such as font color or underline) applied to it.

Choose Clear Hyperlinks or Remove Hyperlinks

Your selected cells will now be free of clickable hyperlinks, with formatting either preserved or removed depending on the option you chose.

How to Remove All Hyperlinks in Excel Automatically?

When your workbook contains hundreds or thousands of hyperlinks, manual removal becomes impractical. In such cases, automation can save significant time. You can remove all hyperlinks at once using VBA (Visual Basic for Applications) or C# with the Spire.XLS library. These methods allow you to clean your sheets efficiently without losing text.

Remove Hyperlinks using VBA

Excel's built-in VBA scripting feature allows you to execute small code snippets that perform tasks automatically. Removing hyperlinks through VBA is one of the fastest ways to clean up your entire workbook.

Remove Hyperlinks from Excel using VBA Macros

Steps to Remove All Hyperlinks from Excel using VBA Macros:

  • Press Alt + F11 to open the VBA Editor.
  • In the editor window, go to Insert → Module.
  • Copy and paste the following VBA code:
Sub RemoveHyperlinks()
    Dim ws As Worksheet
    For Each ws In ThisWorkbook.Worksheets
        ws.Hyperlinks.Delete
    Next ws
End Sub
  • Press F5 to execute the VBA code.

This will remove all hyperlinks from the Excel workbook while keeping the cell text intact.

using Spire.Xls;

namespace RemoveHyperlinks
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // Load the Excel file
            Workbook workbook = new Workbook();
            workbook.LoadFromFile("Hyperlinks.xlsx");

            // Loop through all worksheets
            for (int s = 0; s < workbook.Worksheets.Count; s++)
            {
                Worksheet sheet = workbook.Worksheets[s];

                // Remove all hyperlinks from the worksheet
                for (int i = sheet.HyperLinks.Count - 1; i >= 0; i--)
                {
                    sheet.HyperLinks.RemoveAt(i);
                }
            }

            // Save the modified workbook
            workbook.SaveToFile("NoHyperlinks.xlsx", ExcelVersion.Version2016);
            workbook.Dispose();
        }
    }
}
  • Press F5 to run the C# code.

After running the code, all hyperlinks in the workbook are removed, while all cell text remain unchanged.

Remove Hyperlinks from Excel in C# - Output

Tip: You can customize the code to remove hyperlinks from a specific worksheet, target a particular hyperlink, or process multiple Excel files in bulk.

Best Practices for Deleting Hyperlinks in Excel

While removing hyperlinks in Excel is simple, a few extra steps can help you avoid common problems and keep your worksheet clean and consistent. Here are some best practices to follow:

  • Check for Reappearing Hyperlinks
    Sometimes, hyperlinks reappear when you re-enter or paste data into a cell. To prevent this, go to
    File > Options > Proofing > AutoCorrect Options > AutoFormat As You Type and uncheck Internet and network paths with hyperlinks. This stops Excel from automatically creating new hyperlinks.
  • Use VBA or C# for Large Datasets
    When dealing with large spreadsheets, manually deleting hyperlinks can be inefficient. Instead, use a VBA macro or C# automation to remove all hyperlinks at once. This saves time and ensures consistent results across multiple sheets.
  • Always Backup Before Running Code
    Before running any script or automation, save a backup of your file. Even simple macros can sometimes remove more than intended, especially if hyperlinks are embedded in formulas or comments.

Conclusion

In summary, manual removal is perfect for quick, one-off edits, while VBA or C# automation is ideal for large datasets and repetitive tasks. If you only need to remove a few hyperlinks, Excel's built-in options-right-click menu or the Home tab-are fast and straightforward. For developers or power users managing multiple workbooks, automating the cleanup with VBA or C# saves time and ensures consistency. Choose the method that best fits your workflow, and feel free to experiment with different approaches to see what works best for your Excel files.

FAQs

Q1: How do I remove all hyperlinks in Excel at once?

A1: You can remove all hyperlinks at once using VBA or C# automation. In VBA, use ActiveSheet.Hyperlinks.Delete for a single worksheet or loop through all worksheets to clean the entire workbook. C# libraries like Spire.XLS allow programmatic removal of hyperlinks while keeping the cell text intact.

Convert Excel to JSON and vice versa in C# Step-by-Step Guide

Excel files are widely used to enter, organize, and present tabular data, while JSON is commonly used by APIs and applications to exchange structured data between systems. Converting between these formats allows developers to import spreadsheet data into applications and export application data to Excel for reporting, analysis, or sharing.

In this tutorial, you’ll learn how to convert Excel to JSON and JSON to Excel in C# using Spire.XLS for .NET.

What We Will Cover:

Why Convert Between Excel and JSON?

Converting data between Excel (.xlsx or .xls) and JSON formats is a standard requirement in .NET applications for the following development tasks:

  • Data Ingestion: Parses business-generated spreadsheets into standard server-side objects for backend processing.
  • API Integration: Formats tabular data into standard JSON payloads required by web APIs and microservices.
  • Frontend Serialization: Transforms structured server-side data into lightweight JSON format for consumption by web clients and JavaScript frameworks.
  • NoSQL Storage: Prepares relational or tabular spreadsheet data for direct migration into document databases like MongoDB or Cosmos DB.
  • Automated Reporting: Converts dynamic JSON application data into readable Excel reports for end users.

Prerequisites and Package Installation

Before you begin, ensure your development environment meets these specific requirements.

  • Visual Studio (2019 or later recommended)
  • .NET Environment: .NET Framework 4.0+, .NET Core 3.1+, or .NET 5.0+.
  • NuGet Packages:

Installing the Required NuGet Packages

Option 1: Using .NET Package Manager Console

Open your project in Visual Studio and run the following commands in the Package Manager Console:

Install-Package Spire.XLS
Install-Package Newtonsoft.Json

Option 2: Using .NET CLI

For cross-platform developers using terminal-based environments, execute the following commands inside the project's root folder:

dotnet add package Spire.XLS
dotnet add package Newtonsoft.Json

Basic Excel to JSON Conversion in C# .NET

Starting with Spire.XLS for .NET 15.11.3, developers can export an Excel workbook directly to JSON by calling the SaveToFile() method.

This method is suitable when you want to convert the whole workbook and do not need to customize the generated JSON structure.

Steps to Convert an Excel Workbook to JSON

  1. Instantiate a new Workbook object.
  2. Use LoadFromFile() to load your Excel workbook.
  3. Call SaveToFile() and specify FileFormat.Json as the output format to export the workbook to JSON.

Complete Code Example

using System;
using Spire.Xls;

namespace ConvertExcelToJSON
{
    class Program
    {
        static void Main(string[] args)
        {
            string inputFile = @"Sample.xlsx";
            string outputFile = @"output.json";

            try
            {
                // Create a Workbook object
                using (Workbook workbook = new Workbook())
                {
                    // Load the Excel file
                    workbook.LoadFromFile(inputFile);

                    // Save the entire workbook into a single JSON file
                    // Supported in Spire.XLS 15.11.3 and later
                    workbook.SaveToFile(outputFile, FileFormat.Json);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error during conversion: {ex.Message}");
            }
        }
    }
}

The Output JSON:

The converted JSON structure corresponds to the Excel data as follows:

  • Worksheet name → Becomes a key in the outermost JSON object.
  • Data in each worksheet → Becomes an array, where each object represents a single row.
  • Header row values → Become the default field names for each data object.

The JSON converted from Excel in C#

Advanced Excel to JSON Conversion Scenarios

While saving the entire workbook to JSON is convenient, there are scenarios where you need more control—such as converting only a specific worksheet, cell range, or customizing the JSON output format. Spire.XLS provides flexible approaches to achieve these custom conversions.

Worksheet to JSON

To convert only a specific worksheet rather than the entire workbook, copy the target worksheet to a new workbook and then save that workbook as JSON.

Steps to Convert a Specific Worksheet to JSON

  1. Load the source workbook using LoadFromFile().
  2. Get the target worksheet by its index or name.
  3. Create a new Workbook object for the output.
  4. Use the Worksheets.AddCopy() method to copy the target worksheet to the new workbook.
  5. Call SaveToFile() with FileFormat.Json on the new workbook.

Complete Code Example

using System;
using Spire.Xls;

namespace ConvertWorksheetToJSON
{
    class Program
    {
        static void Main(string[] args)
        {
            string inputFile = @"Sample.xlsx";
            string outputFile = @"sheet_output.json";

            try
            {
                using (Workbook sourceWorkbook = new Workbook())
                {
                    sourceWorkbook.LoadFromFile(inputFile);

                    // Access the first worksheet by index (or by name: sourceWorkbook.Worksheets["sheetName"])
                    Worksheet targetSheet = sourceWorkbook.Worksheets[0];

                    using (Workbook newWorkbook = new Workbook())
                    {
                        // Remove default worksheets from the new workbook
                        newWorkbook.Worksheets.Clear();

                        // Copy the target worksheet into the new workbook
                        newWorkbook.Worksheets.AddCopy(targetSheet);

                        // Save the single worksheet as JSON
                        newWorkbook.SaveToFile(outputFile, FileFormat.Json);
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error: {ex.Message}");
            }
        }
    }
}

Cell Range to JSON

If you only need to export a portion of worksheet data—such as a specific table or range—copy the desired range to a new workbook and then save the result file as JSON.

Steps to Convert a Cell Range to JSON

  1. Load the source workbook.
  2. Get the target worksheet containing the data.
  3. Define the range you want to export (e.g., worksheet.Range["A1:D3"]).
  4. Instantiate a new Workbook object.
  5. Copy the range data to a new worksheet in the new workbook with Worksheet.Copy().
  6. Call SaveToFile() with FileFormat.Json to save the new workbook as a .json file.

Complete Code Example

using System;
using Spire.Xls;

namespace ConvertExcelToJSON
{
    class Program
    {
        static void Main(string[] args)
        {
            string inputFile = @"Sample.xlsx";
            string outputFile = @"range_output.json";

            try
            {
                using (Workbook sourceWorkbook = new Workbook())
                {
                    sourceWorkbook.LoadFromFile(inputFile);
                    Worksheet sourceWorksheet = sourceWorkbook.Worksheets[0];

                    // Define the range to export (e.g., A1:D3)
                    CellRange sourceRange = sourceWorksheet.Range["A1:D3"];

                    using (Workbook targetWorkbook = new Workbook())
                    {
                        // Remove the default worksheets
                        targetWorkbook.Worksheets.Clear(); 

                        // Add a worksheet for the selected range
                        Worksheet targetWorksheet = targetWorkbook.Worksheets.Add("RangeData"); 

                        // Create a destination range with the same dimensions
                        CellRange destinationRange = targetWorksheet.Range["A1:D3"]; 

                        // Copy values and styles to the new workbook
                        sourceWorksheet.Copy(sourceRange, destinationRange, true);

                        // Export the isolated range to JSON
                        targetWorkbook.SaveToFile(outputFile, FileFormat.Json);
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error exporting cell range: {ex.Message}");
            }
        }
    }
}

Customize JSON Output Formatting

The SaveToFile() method provides a quick conversion, but the output format is fixed. If you need greater control over the JSON output, export the worksheet data to a DataTable with ExportDataTable() and serialize it with Newtonsoft.Json. This allows you to customize property names, null handling, date formats, and indentation.

Steps for Custom JSON Output Formatting

  1. Load the Excel File.
  2. Access the worksheet and export its data to a DataTable using ExportDataTable().
  3. Configure JsonSerializerSettings to define formatting rules (camelCase, null handling, date format, etc.).
  4. Serialize the DataTable using JsonConvert.SerializeObject() with the settings.
  5. Save the JSON string to a file.

Complete Code Example

using System;
using System.Data;
using System.IO;
using Spire.Xls;
using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;

namespace ConvertExcelToJSON
{
    class Program
    {
        static void Main(string[] args)
        {
            string excelFilePath = @"Sample.xlsx";
            string jsonOutputPath = "custom_output.json";

            try
            {
                using (Workbook workbook = new Workbook())
                {
                    workbook.LoadFromFile(excelFilePath);
                    Worksheet worksheet = workbook.Worksheets[0];

                    // Convert tabular data directly into an in-memory DataTable structure
                    DataTable dataTable = worksheet.ExportDataTable(worksheet.AllocatedRange, true);

                    // Define custom JSON serialization rules
                    JsonSerializerSettings settings = new JsonSerializerSettings
                    {
                        Formatting = Formatting.Indented, // Structured, readable format
                        ContractResolver = new CamelCasePropertyNamesContractResolver(), // camelCase naming conventions
                        NullValueHandling = NullValueHandling.Ignore, // Omit null fields from output string
                        DateFormatString = "yyyy-MM-dd" // Explicit date string overrides
                    };

                    // Serialize the data structure to string with settings applied
                    string jsonResult = JsonConvert.SerializeObject(dataTable, settings);

                    // Write string payload out to target destination
                    File.WriteAllText(jsonOutputPath, jsonResult);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error during custom serialization: {ex.Message}");
            }
        }
    }
}

Explanation of Customization Options

Setting Purpose
Formatting = Formatting.Indented Produces human‑readable JSON with line breaks and indentation.
CamelCasePropertyNamesContractResolver Applies camelCase naming to compatible column names, which is a common convention in JSON APIs.
NullValueHandling = NullValueHandling.Ignore Omits values represented as null or DBNull.Value.
DateFormatString = "yyyy-MM-dd" Formats values represented as DateTime or DateTimeOffset.

Note on Column Names with Spaces:
When Excel headers contain spaces (e.g., "First Name"), the generated JSON keys will retain those spaces. Consumers must use bracket notation (obj["First Name"]) instead of dot notation. For cleaner camelCase property names, normalize the DataTable column names by iterating DataTable.Columns — e.g., remove spaces or apply a custom naming convention before serialization.

You can further customize the output by adding custom JsonConverter implementations, modifying date handling, or using different ContractResolver strategies. For more details, refer to the Newtonsoft.Json documentation.

The Excel file converted from JSON in C#

Handling Wrapped or Nested JSON

The direct DataTable deserialization works best with a flat JSON array. If the records are wrapped inside a root object or contain nested objects and arrays, extract and flatten the required values before converting them to a DataTable.

For example, the following JSON string contains both a root wrapper and nested data:

string jsonInput = @"
{
  ""status"": ""success"",
  ""data"": [
    {
      ""Name"": ""John Smith"",
      ""Department"": {
        ""Id"": 10,
        ""Name"": ""Sales""
      },
      ""Skills"": [
        ""Negotiation"",
        ""CRM""
      ]
    },
    {
      ""Name"": ""Jane Doe"",
      ""Department"": {
        ""Id"": 20,
        ""Name"": ""Marketing""
      },
      ""Skills"": [
        ""Content Writing"",
        ""Analytics""
      ]
    }
  ]
}";

The following method extracts the data array, flattens the nested values, and returns a DataTable:

using System.Data;
using System.IO;
using System.Linq;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

private static DataTable ConvertNestedJsonToDataTable(string jsonInput)
{
    // Parse either a root object or a root array.
    JToken rootToken = JToken.Parse(jsonInput);

    // Accept a root array or an array stored in the "data" property.
    JArray records = rootToken as JArray
        ?? ((rootToken as JObject)?["data"] as JArray)
        ?? throw new InvalidDataException(
            "The JSON does not contain a valid record array.");

    // Flatten nested objects and arrays into tabular fields.
    var flattenedRecords = records.Select(record => new
    {
        Name = (string)record["Name"] ?? string.Empty,

        // Convert the nested Department object into separate columns.
        DepartmentId = (int?)record["Department"]?["Id"],
        DepartmentName =
            (string)record["Department"]?["Name"] ?? string.Empty,

        // Join the Skills array into a comma-separated string.
        Skills = string.Join(
            ", ",
            record["Skills"]?.Values<string>()
                ?? Enumerable.Empty<string>())
    });

    // Convert the flattened records into a DataTable.
    string flattenedJson =
        JsonConvert.SerializeObject(flattenedRecords);

    DataTable dataTable =
        JsonConvert.DeserializeObject<DataTable>(flattenedJson);

    if (dataTable == null || dataTable.Columns.Count == 0)
        throw new InvalidDataException(
            "The JSON contains no tabular records.");

    return dataTable;
}

The returned DataTable can then be inserted into a worksheet using InsertDataTable():

DataTable nestedTable = ConvertNestedJsonToDataTable(jsonInput);
worksheet.InsertDataTable(nestedTable, true, 1, 1);

Note: This mapping is based on the structure of the sample JSON. For other JSON schemas, adjust the selected properties and output columns accordingly.

Tips and Best Practices

When converting between Excel and JSON, following these best practices will help ensure data integrity and usability:

  • Validate Data Types: Ensure that data types (dates, numbers, booleans) are correctly formatted to avoid issues during conversion.
  • Handle Empty Cells: Decide how to treat empty cells (convert to null, omit, or use default values) to maintain data integrity.
  • Use Consistent Naming Conventions: Standardize column names in Excel for clear and consistent JSON keys.
  • Test Thoroughly: Always test the conversion processes to ensure valid JSON output and accurate Excel representation.
  • Include Headers: When converting JSON to Excel, always insert headers for improved readability and usability.

FAQs

Do I need Microsoft Excel installed to use these examples?

No. Spire.XLS is a standalone .NET library that reads, writes, and converts Excel files without any dependency on Microsoft Office or Excel Interop.

Can I convert older .xls (97–2003) files as well as .xlsx to JSON?

Yes. LoadFromFile() automatically detects the file format, so the same code works for both .xls and .xlsx sources.

Can I convert nested JSON to Excel?

JsonConvert.DeserializeObject<DataTable>() works with flat JSON arrays. For nested JSON, flatten the structure into a simple list of objects before calling InsertDataTable().

Does this approach work in ASP.NET Core or other cross-platform .NET apps?

Yes. Spire.XLS supports .NET Framework, .NET Core, and .NET 5–10, so the same code runs in console apps, ASP.NET Core services, and cross-platform (Linux/macOS) environments.

Conclusion

This tutorial demonstrated how to convert Excel workbooks, individual worksheets, and cell ranges to JSON, as well as how to import JSON data into Excel in C#. By combining Spire.XLS with Newtonsoft.Json, you can handle both straightforward conversions and scenarios that require custom formatting or nested data processing.
