What is Markdown?

Markdown is a lightweight markup language designed for readability and ease of writing. Unlike HTML, which can be verbose and harder to write by hand, Markdown uses simple syntax to indicate headings, lists, links, images, and more.

Example Markdown:

# This is a Heading

This is a paragraph with \*\*bold text\*\* and \*italic text\*.

- Item 1

- Item 2

Even in its raw form, Markdown is easy to read, which makes it popular for documentation, blogging, README files, and technical writing.

For more on Markdown syntax, see the Markdown Guide.

Why Convert Markdown to HTML?

While Markdown is excellent for authoring content, web browsers cannot render it natively. Converting Markdown to HTML allows you to:

• Publish content on websites – Most CMS platforms require HTML for web pages.
• Enhance styling – HTML supports CSS and JavaScript for advanced formatting and interactivity.
• Maintain compatibility – HTML is universally supported by browsers, ensuring content displays correctly everywhere.
• Integrate with web frameworks – Frameworks like React, Vue, and Angular require HTML as the base for rendering components.

Introducing Spire.Doc for Python

Spire.Doc for Python is a robust library for handling multiple document formats. It supports reading and writing Word documents, Markdown files, and exporting content to HTML. The library allows developers to convert Markdown directly to HTML with minimal code, preserving proper formatting and structure.

In addition to HTML, Spire.Doc for Python also allows you to convert Markdown to Word in Python or convert Markdown to PDF in Python, making it particularly useful for developers who want a unified tool for handling Markdown across different output formats.

Benefits of Using Spire.Doc for Python for Markdown to HTML Conversion

• Easy-to-use API – Simple, intuitive methods that reduce development effort.
• Accurate formatting – Preserves all Markdown elements such as headings, lists, links, and emphasis in HTML.
• No extra dependencies – Eliminates the need for manual parsing or third-party libraries.
• Flexible usage – Supports both single-file conversion and automated batch processing.

Step-by-Step Guide: Converting Markdown to HTML in Python

Now that you understand the purpose and benefits of converting Markdown to HTML, let’s walk through a clear, step-by-step process to transform your Markdown files into structured, web-ready HTML.

Step 1: Install Spire.Doc for Python

First, ensure that Spire.Doc for Python is installed in your environment. You can install it directly from PyPI using pip:

pip install spire.doc

Step 2: Prepare Your Markdown File

Next, create a sample Markdown file that you want to convert. For example, example.md:

Step 3: Write the Python Script

Now, write a Python script that loads the Markdown file and converts it to HTML:

from spire.doc import *

# Create a Document object
doc = Document()

# Load the Markdown file
doc.LoadFromFile("example.md", FileFormat.Markdown)

# Save the document as HTML
doc.SaveToFile("example.html", FileFormat.Html)

# Close the document
doc.Close()

Explanation of the code:

• Document() initializes a new document object.
• LoadFromFile("example.md", FileFormat.Markdown) loads the Markdown file into memory.
• SaveToFile("example.html", FileFormat.Html) converts the loaded content into HTML and saves it to disk.
• doc.Close() ensures resources are released properly, which is particularly important when processing multiple files or running batch operations.

Step 4: Verify the HTML Output

Finally, open the generated example.html file in a web browser or HTML editor. Verify that the Markdown content has been correctly converted.

Automating Batch Conversion

You can convert multiple Markdown files in a folder automatically:

import os
from spire.doc import *

# Set the folder containing Markdown files
input_folder = "markdown_files"

# Set the folder where HTML files will be saved
output_folder = "html_files"

# Create the output folder if it doesn't exist
os.makedirs(output_folder, exist_ok=True)

# Loop through all files in the input folder
for filename in os.listdir(input_folder):
    # Process only Markdown files
    if filename.endswith(".md"):
        # Create a new Document object for each file
        doc = Document()

        # Load the Markdown file into the Document object
        doc.LoadFromFile(os.path.join(input_folder, filename), FileFormat.Markdown)

        # Construct the output file path by replacing .md extension with .html
        output_file = os.path.join(output_folder, filename.replace(".md", ".html"))

        # Save the loaded Markdown content as HTML
        doc.SaveToFile(output_file, FileFormat.Html)

        # Close the document to release resources
        doc.Close()

This approach allows you to process multiple Markdown files efficiently and generate corresponding HTML files automatically.

Best Practices for Markdown to HTML Conversion

While the basic steps are enough to complete a Markdown-to-HTML conversion, following a few best practices will help you avoid common pitfalls, improve compatibility, and ensure your output is both clean and professional:

• Use proper Markdown syntax – Ensure headings, lists, links, and emphasis are correctly written.
• Use UTF-8 Encoding: Always save your Markdown files in UTF-8 encoding to avoid issues with special characters or non-English text.
• Batch Processing: If you need to convert multiple files, wrap your script in a loop and process entire folders. This saves time and ensures consistent formatting across documents.
• Enhance Styling: Remember that HTML gives you the flexibility to add CSS and JavaScript for custom layouts, responsive design, and interactivity—something not possible in raw Markdown.

• Search for Spire.XLS and install it.

Or, install it directly using the Package Manager Console :

PM> Install-Package Spire.XLS

Option 2: Manual installation

• Download the Spire.XLS package from our official website
• Add a reference to Spire.Xls.dll in your project.

Once installed, you’re ready to start writing to Excel in C#.

How to Create a New Excel File in C#

The first step is to create a new workbook and add a worksheet. Here’s how:

using Spire.Xls;

namespace CreateNewExcel
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create a new workbook
            Workbook workbook = new Workbook();

            // Remove default worksheets
            workbook.Worksheets.Clear();

            // Add a worksheet
            Worksheet sheet = workbook.Worksheets.Add("Report");

            // Save the empty Excel file
            workbook.SaveToFile("NewExcelFile.xlsx", ExcelVersion.Version2016);
            workbook.Dispose();
        }
    }
}

At this point, you have created an empty Excel file with a worksheet named “Report”. Next, let’s write data into it.

Write Different Data Types to Excel Cells in C#

Spire.XLS allows you to write various data types directly to Excel cells. Below are common examples:

Write Text Values

sheet.Range["A1"].Text = "Hello Excel!";

Write Numeric Values

sheet.Range["A2"].NumberValue = 123.45;

Write Date and Time

sheet.Range["A3"].DateTimeValue = DateTime.Now;
sheet.Range["A3"].NumberFormat = "yyyy-mm-dd hh:mm";

Write Boolean Values

sheet.Range["A4"].BooleanValue = true;

Write TimeSpan Values

sheet.Range["A5"].TimeSpanValue = new TimeSpan(2, 30, 0); // 2 hours 30 minutes;
sheet.Range["A5"].NumberFormat = "[h]:mm:ss";

Insert Formulas

sheet.Range["A6"].Formula = "=SUM(A2,100)";

Insert HTML Formatted Strings

string htmlText = "<span style=\"font-family: Times New Roman; color: blue; font-size: 15pt;\">Hello
<strong>Spire.XLS</strong></span>";
sheet.Range["A7"].HtmlString = htmlText;

Write General Values Without Specific Type

sheet.Range["A8"].Value = "General Value";

Output:

Write Bulk Data to Excel Sheets in C#

When dealing with larger datasets, writing values cell by cell isn’t efficient. Spire.XLS provides methods to insert arrays , and DataTables directly. Other data structures can be converted to arrays or DataTables before being written to the Excel sheet.

Write Arrays to Excel

Spire.XLS provides the Worksheet.InsertArray(string[] stringArray, int firstRow, int firstColumn, bool isVertical) method, allowing developers to insert one-dimensional or two-dimensional arrays into a specified range of cells in a worksheet.

string[,] data = {
    { "Name", "Age", "Country" },
    { "Alice", "30", "USA" },
    { "Bob", "28", "UK" },
    { "Charlie", "35", "Canada" }
};
sheet.InsertArray(data, 1, 1);

Output:

Write DataTables to Excel

To import data from a DataTable to a worksheet, use the Worksheet.InsertDataTable(DataTable dataTable, bool columnHeaders, int firstRow, int firstColumn, bool transTypes) method.

using System.Data;

DataTable dt = new DataTable();
dt.Columns.Add("ID", typeof(int));
dt.Columns.Add("Product", typeof(string));
dt.Columns.Add("Price", typeof(double));

// Add rows
dt.Rows.Add(1, "Laptop", 1200.5);
dt.Rows.Add(2, "Tablet", 450.99);
dt.Rows.Add(3, "Phone", 799.0);

// Insert DataTable starting at cell A1
sheet.InsertDataTable(dt, true, 1, 1, true);

Output:

On the contrary, you can export data from Excel to DataTable by using the ExportDataTable method of the Worksheet class.

Write Lists to Excel

While Spire.XLS does not provide a direct method for writing lists to Excel, you can convert lists to a DataTable and then use the InsertDataTable method to write the DataTable to Excel.

using Spire.Xls;
using System.Data;

namespace WriteListToExcel
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create a Workbook instance
            Workbook workbook = new Workbook();

            // Remove default worksheets
            workbook.Worksheets.Clear();

            // Add a worksheet and name it
            Worksheet worksheet = workbook.Worksheets.Add("Students");

            // Create a list with student data
            List<Student> students = new List<Student>
            {
                new Student("Michael", "Johnson", 20, "Computer Science", 3.8),
                new Student("Sarah", "Williams", 22, "Mathematics", 3.6),
                new Student("Jessica", "Brown", 19, "Physics", 3.9),
                new Student("David", "Smith", 21, "Chemistry", 3.7),
                new Student("Emily", "Davis", 23, "Biology", 3.5)
            };

            // Convert the list to DataTable
            DataTable dataTable = ConvertListToDataTable(students);

            // Write DataTable to the worksheet
            worksheet.InsertDataTable(dataTable, true, 1, 1, true);

            // Set column width
            worksheet.AllocatedRange.ColumnWidth = 12;

            // Align content to left
            worksheet.AllocatedRange.HorizontalAlignment = HorizontalAlignType.Left;

            // Save to an Excel file
            workbook.SaveToFile("InsertStudents.xlsx", ExcelVersion.Version2016);

            // Dispose resources
            workbook.Dispose();
        }

        static DataTable ConvertListToDataTable(List<Student> students)
        {
            DataTable dataTable = new DataTable();

            // Add columns
            dataTable.Columns.Add("FirstName", typeof(string));
            dataTable.Columns.Add("LastName", typeof(string));
            dataTable.Columns.Add("Age", typeof(int));
            dataTable.Columns.Add("Major", typeof(string));
            dataTable.Columns.Add("GPA", typeof(double));

            // Add rows
            foreach (var student in students)
            {
                DataRow row = dataTable.NewRow();
                row["FirstName"] = student.FirstName;
                row["LastName"] = student.LastName;
                row["Age"] = student.Age;
                row["Major"] = student.Major;
                row["GPA"] = student.GPA;
                dataTable.Rows.Add(row);
            }

            return dataTable;
        }
    }

    class Student
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public int Age { get; set; }
        public string Major { get; set; }
        public double GPA { get; set; }

        public Student(string firstName, string lastName, int age, string major, double gpa)
        {
            FirstName = firstName;
            LastName = lastName;
            Age = age;
            Major = major;
            GPA = gpa;
        }
    }
}

Output:

Save and Export Excel Files

After writing data, you’ll want to save or export the Excel file. Spire.XLS supports multiple formats including XLSX, CSV, and PDF .

// Save as XLSX
workbook.SaveToFile("Output.xlsx", ExcelVersion.Version2016);

// Save as CSV
workbook.SaveToFile("Output.csv", ",", Encoding.UTF8);

// Export as PDF
workbook.SaveToFile("Output.pdf", FileFormat.PDF);

For web applications, you can also save to a MemoryStream :

using (MemoryStream ms = new MemoryStream())
{
    workbook.SaveToStream(ms, FileFormat.Version2016);
    // Write to Response in ASP.NET if needed
}

Common Issues and Solutions

1. Incorrect Date or Time Format

Issue: Dates/times appear as serial numbers.

Solution :

• Apply a proper number format to the cell:

sheet.Range["A1"].DateTimeValue = DateTime.Now;
sheet.Range["A1"].NumberFormat = "yyyy-mm-dd hh:mm";

2. Data Overwriting or Misaligned

Issue : Writing arrays or DataTables overwrites existing data unintentionally.

Solution :

• Check firstRow and firstColumn parameters in InsertArray() or InsertDataTable().
• Use separate worksheets or offset ranges if necessary.

3. Large Dataset Performance Issues

Issue : Writing thousands of rows is slow.

Solution :

• Use bulk writing methods instead of looping cell by cell.
• Apply styles after inserting data to avoid repeated formatting overhead.

4. Formula Not Calculating Correctly

Issue : Excel formulas inserted via sheet.Range["A1"].Formula do not return expected results.

Solution :

• Ensure the formula syntax is correct for Excel (e.g., =SUM(A2:A10)).
• Call workbook.CalculateAllValue() to update all formulas before saving if needed.

• Name it: PdfController.cs.
• Replace the default code with this:

using Microsoft.AspNetCore.Mvc;
using Spire.Pdf;
using Spire.Pdf.Graphics;
using System.Drawing;

namespace PdfDemoApp.Controllers
{
    public class PdfController : Controller
    {
        public IActionResult CreatePdf()
        {
            // Create a new PDF document
            PdfDocument doc = new PdfDocument();
            PdfPageBase page = doc.Pages.Add(PdfPageSize.A4, new PdfMargins(40));

            // Draw text on the page
            PdfFont font = new PdfFont(PdfFontFamily.Helvetica, 25f);
            PdfSolidBrush brush = new PdfSolidBrush(Color.Black);
            page.Canvas.DrawString("Hello from ASP.NET Core!", font, brush, 10, 50);

            // Save to memory stream
            using (MemoryStream ms = new MemoryStream())
            {
                doc.SaveToStream(ms);
                doc.Close();
                ms.Position = 0;

                // Return PDF file
                return File(ms.ToArray(), "application/pdf", "Generated.pdf");
            }
        }
    }
}

Step 4: (Optional) Add a Button or Link in Your View

Open Views/Home/Index.cshtml (or whichever view is your homepage).

In addition to text, Spire.PDF supports adding a wide range of elements to PDF, such as images, shapes, tables, lists, hyperlinks, annotations, and watermarks. For more details and advanced usage, check the .NET PDF Tutorials.

Create PDF from HTML in ASP.NET Core

Spire.PDF allows you to convert HTML content directly into PDF files. This feature is particularly useful for generating invoices, reports, receipts, or exporting styled web pages with consistent formatting.

To render HTML as PDF, Spire.PDF relies on an external rendering engine. You can choose between Qt WebEngine or Google Chrome . In this guide, we’ll use Qt WebEngine .

Setup the Qt plugin:

1. Download the Qt WebEngine plugin for your operating system:

   • Windows x86
   • Windows x64
   • Linux x64
   • Mac x64

2. Extract the package to obtain the plugins directory, e.g.: C:\plugins-windows-x64\plugins

3. Register the plugin path inyour code:

HtmlConverter.PluginPath = @"C:\plugins-windows-x64\plugins";

Once the plugin is ready, you can follow the steps from the previous section and add the code snippet below to your controller to generate PDF output from HTML content.

using Microsoft.AspNetCore.Mvc;
using Spire.Additions.Qt;
using Spire.Pdf.Graphics;
using System.Drawing;

namespace PdfDemoApp.Controllers
{
    public class PdfController : Controller
    {
        [HttpGet]
        public IActionResult HtmlToPdf()
        {
            // Example HTML string
            string html = @"
                <html>
                  <head>
                    <style>
                      body { font-family: Arial, sans-serif; }
                      h1 { color: #2563eb; }
                    </style>
                  </head>
                  <body>
                    <h1>ASP.NET Core: Create PDF from HTML</h1>
                    <p>This PDF was generated using the Qt-based converter.</p>
                  </body>
                </html>";

            // Path to the Qt plugin folder
            // ⚠️ Ensure this folder exists on your server/deployment environment
            string pluginPath = @"C:\plugins-windows-x64\plugins";
            HtmlConverter.PluginPath = pluginPath;

            // Create a temp file path (on server side)
            string tempFile = Path.GetTempFileName();

            // Convert HTML string → PDF using Qt
            HtmlConverter.Convert(
                html,
                tempFile,
                enableJavaScript: true,
                timeout: 100000,                        // milliseconds
                pageSize: new SizeF(595, 842),          // A4 page size in points
                margins: new PdfMargins(40),            // 40pt margins
                LoadHtmlType.SourceCode                 // Load from HTML string
            );

            // Read the generated PDF into memory
            byte[] fileBytes = System.IO.File.ReadAllBytes(tempFile);

            // Clean up temp file
            System.IO.File.Delete(tempFile);

            // Return PDF to browser as download
            return File(fileBytes, "application/pdf", "HtmlToPdf.pdf");
        }
    }
}

Best Practices for ASP.NET PDF Generation

• Use memory streams instead of disk storage for performance and scalability.
• Cache static PDFs (like terms & conditions or forms) to reduce server load.
• Use HTML-to-PDF for dynamic reports with CSS styling.
• Consider templates (like Word-to-PDF with Spire.Doc) when documents have complex layouts.
• Secure sensitive PDFs with password protection or access permissions.

Conclusion

With Spire.PDF for .NET, you can easily generate PDF in ASP.NET Core applications. Whether you’re creating PDFs from scratch or performing HTML-to-PDF conversion in C# , Spire.PDF provides a reliable, developer-friendly solution—no external dependencies required.

If you also need to generate PDFs from Word documents, that feature is available via Spire.Doc for .NET, another product in the Spire family. Together, they cover the full range of PDF document generation scenarios.

By integrating these tools, developers can streamline workflows, reduce reliance on Adobe or other third-party components, and ensure consistent, professional-quality output. This makes your ASP.NET PDF solutions more scalable, maintainable, and ready for enterprise use.
