Implementation Guide

Here’s how to convert an Excel spreadsheet into a PDF document using GroupDocs.Conversion.

Define Load Options

Configure load options to control the conversion process. Here, we focus on hiding comments and rendering each sheet on its own page:

Hiding Comments and Setting Page Layout

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

// Define load options for the conversion process
Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new SpreadsheetLoadOptions
{
    // Hide comments in the output PDF to maintain a clean look
    PrintComments = SpreadsheetPrintComments.PrintNoComments,
    
    // Render each sheet of the spreadsheet on a separate page
    OnePagePerSheet = true
};

Explanation:

  • PrintComments: Ensures no comments are visible in the final PDF.
  • OnePagePerSheet: Each Excel worksheet is converted into an individual page for better organization.

Perform Conversion

Execute the conversion using the specified load options:

string inputFile = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "SAMPLE_XLSX");
string outputFolder = Path.Combine("YOUR_OUTPUT_DIRECTORY");
string outputFile = Path.Combine(outputFolder, "converted.pdf");

using (Converter converter = new Converter(inputFile, getLoadOptions))
{
    // Set PDF conversion options with default settings for simplicity
    PdfConvertOptions options = new PdfConvertOptions();
    
    // Convert the spreadsheet to a PDF file
    converter.Convert(outputFile, options);
}

Explanation:

  • Converter: Initializes the conversion process using your input file and load options.
  • PdfConvertOptions: Configures how the output PDF should be handled. Here, defaults are used for simplicity.

Troubleshooting Tips

Common issues you might encounter include:

  1. File Not Found: Ensure paths to your input and output files are correct.
  2. License Issues: Double-check that the license file path is correctly set if applicable.
