How to Convert XLSB to PDF Using GroupDocs.Conversion for .NET

Introduction

Looking to effortlessly convert your Excel Binary Workbook (.xlsb) files into PDF format with minimal hassle? Whether you’re automating report generation or integrating document conversion into your app, GroupDocs.Conversion for .NET offers a powerful, simple-to-use solution. In this comprehensive guide, I’ll walk you through each step of converting an XLSB file to PDF, ensuring you understand the process thoroughly.

Prerequisites for XLSB to PDF Conversion

Before diving into the code, make sure you have everything you need. Here’s a quick rundown:

• .NET Framework or .NET Core project: Ensure you have a working project where you want to embed this functionality.
• GroupDocs.Conversion for .NET: Download and install the GroupDocs.Conversion library — you can grab the latest version from their official releases page.
• A sample XLSB file: Have your Excel binary workbook ready (e.g., sample.xlsb).
• A license key (optional): For production use, consider obtaining a license. For testing, the free trial works fine.

Step 1: Import Necessary Packages

Start by importing the essential namespaces. This is how your code will recognize and use the GroupDocs.Conversion classes and methods.

using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

Tip: If you haven’t installed the package yet, use NuGet Package Manager by running:

Install-Package GroupDocs.Conversion.Net

Step 2: Set Up the Output Directory and Files

Define where your converted PDF will go. It helps to organize output files into a dedicated folder.

// Define your output folder path
string outputFolder = Path.Combine(Directory.GetCurrentDirectory(), "Output");
Directory.CreateDirectory(outputFolder); // Make sure the directory exists

// Define output PDF file path
string outputFile = Path.Combine(outputFolder, "converted-file.pdf");

Why is this important? Keeping output organized ensures easier management of files, especially when processing multiple conversions.

Step 3: Load the XLSB File

The core of the process is loading your source file. Place your XLSB file in a known location or pass its path directly.

string sourceXlsbFile = @"C:\Path\To\Your\File\sample.xlsb"; // Update with your file path

Pro Tip: Always verify the file exists before attempting to load it to avoid runtime errors.

Step 4: Initialize the Converter

Create an instance of the Converter class, passing the source file path. This object is your gateway to converting documents.

using (var converter = new Converter(sourceXlsbFile))
{
    // Conversion options and process will go here
}

Think of it like opening a book — this is your starting point for reading and transforming documents.

Step 5: Choose Conversion Options

Since we want a PDF, use the PdfConvertOptions class. It lets you customize the output, like page layout, quality, or orientation if needed.

var options = new PdfConvertOptions();

Step 6: Perform the Conversion

Invoke the Convert() method, passing in the output file path and options object. It processes the file asynchronously and saves the PDF.

converter.Convert(outputFile, options);

Imagine pressing ‘Convert’ on an app — the tool does the heavy lifting for you.

Step 7: Finalize and Confirm

After conversion, confirm success with a console message, or add error handling for robustness.

Console.WriteLine($"Conversion completed successfully! Check out the output at: {outputFolder}");

Tip: Wrap your code in try-catch blocks for production to catch exceptions gracefully.

Conclusion

Converting an XLSB to PDF with GroupDocs.Conversion for .NET is straightforward and highly customizable. Whether you’re automating report generation or integrating document workflows into your app, this process is reliable and efficient.

Remember, the key is understanding your source files, setting the right options, and handling exceptions properly. With this foundation, you can adapt the conversion process to suit more complex needs like batch conversions or custom formatting.
