Convert Spreadsheet to PDF with Advanced Options

Overview

Convert an Excel file into a PDF while displaying grid lines and ensuring each sheet appears on one page in the output document.

Step 1: Define Load Options

Configure load options for advanced settings:

using GroupDocs.Conversion.Options.Load;

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

Explanation: SpreadsheetLoadOptions lets you configure how the spreadsheet is loaded. Setting ShowGridLines to true includes grid lines in your PDF, and OnePagePerSheet ensures each sheet fits on a single page.

Step 2: Convert Using the Converter Class

Use the Converter class to perform the conversion:

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

string inputFilePath = "sample.xlsx";
string outputFolder = "output";
string outputFile = Path.Combine(outputFolder, "converted.pdf");

// Initialize Converter with load options
using (Converter converter = new Converter(inputFilePath, getLoadOptions))
{
    PdfConvertOptions options = new PdfConvertOptions(); // Set up PDF conversion options
    converter.Convert(outputFile, options); // Perform the conversion
}

Explanation: The Converter class takes in your Excel file path and load options. The PdfConvertOptions class specifies any additional settings for the PDF output.
