Implementation Guide

In this section, we’ll explore two main features of converting spreadsheets to PDFs using GroupDocs.Conversion for .NET: applying advanced options and configuring load settings.

Convert Spreadsheet to PDF with Advanced Options

Overview: This feature allows you to convert a spreadsheet document (e.g., XLSX) into a PDF file while utilizing advanced loading options. You can skip empty rows/columns and configure each sheet to be converted into a single PDF page.

Step-by-Step Implementation:

  1. Define Output Directory Set up your output directory path using placeholders for flexibility:

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

  2. Configure Load Options Customize load options to skip empty rows/columns and convert each sheet into a single PDF page:

    Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new SpreadsheetLoadOptions
{
    SkipEmptyRowsAndColumns = true,
    OnePagePerSheet = true
};

  3. Initialize Converter Set up the converter with your input file and configured load options:

    string inputFile = "YOUR_DOCUMENT_DIRECTORY" + "/sample.xlsx";
using (Converter converter = new Converter(inputFile, getLoadOptions))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert(outputFile, options);
}

Configurable Load Options for Spreadsheet Conversion

Overview: This feature lets you define and customize load options before conversion. It’s useful for scenarios where preprocessing the spreadsheet can enhance the final output.

Step-by-Step Implementation:

  1. Define Custom Load Options Create a method to configure your desired load settings:

    public static Func<LoadContext, LoadOptions> GetLoadOptions()
{
    return loadContext => new SpreadsheetLoadOptions
    {
        SkipEmptyRowsAndColumns = true,
        OnePagePerSheet = true
    };
}

  2. Utilize Custom Load Options Use these configurable options in your conversion process:

    Func<LoadContext, LoadOptions> loadOptions = GetLoadOptions();
string inputFile = "YOUR_DOCUMENT_DIRECTORY" + "/sample.xlsx";
using (Converter converter = new Converter(inputFile, loadOptions))
{
    PdfConvertOptions pdfOptions = new PdfConvertOptions();
    converter.Convert(outputFile, pdfOptions);
}

Troubleshooting Tips:

  • Ensure the input file path is correct and accessible.
  • Verify that all necessary permissions are set for reading/writing files.
  • Check if GroupDocs.Conversion package version matches your project setup.

Practical Applications

Here are some real-world use cases where converting spreadsheets to PDFs can be invaluable:

  1. Financial Reporting: Generate standardized PDF reports from dynamic Excel sheets for stakeholder distribution.
  2. Collaboration and Sharing: Convert shared spreadsheet data into PDFs for consistent viewing across different platforms.
  3. Data Archiving: Archive historical financial or inventory data in a universally accessible format.

Integration with other .NET systems like ASP.NET Core can automate the conversion process within web applications, enhancing user experience by providing downloadable reports directly from your application interface.
