Implementation Guide

Now that we have the setup ready, let’s implement the feature of converting XLS files to PDF.

Loading the Source File

Define paths for your input and output directories. Replace 'YOUR_DOCUMENT_DIRECTORY' and 'YOUR_OUTPUT_DIRECTORY' with actual paths on your system:

string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";

// Define the path for the source XLS file and the output PDF file
string xlsFilePath = Path.Combine(documentDirectory, "sample.xls");
string pdfOutputFile = Path.Combine(outputDirectory, "xls-converted-to.pdf");

Performing the Conversion

To convert your Excel file to a PDF:

try
{
    // Load the source XLS file
    using (var converter = new Converter(xlsFilePath))
    {
        // Set conversion options for PDF format
        var options = new PdfConvertOptions();

        // Perform conversion and save the output PDF file
        converter.Convert(pdfOutputFile, options);
    }
}
catch(Exception ex)
{
    Console.WriteLine("An error occurred: " + ex.Message);
}

Explanation

  • Converter Class: Responsible for loading your document.
  • PdfConvertOptions: Specifies that we want to convert our document into a PDF format.
