Implementation Guide

This guide breaks down the conversion process into manageable steps. Each section highlights what you’ll accomplish, along with step-by-step instructions.

Load Source VSSX File

Overview Begin by loading your source VSSX file using the Converter class from GroupDocs.Conversion.

Step 1: Specify File Path Replace "YOUR_DOCUMENT_DIRECTORY\\sample.vssx" with the path to your VSSX file:

var sourceFilePath = "YOUR_DOCUMENT_DIRECTORY\\\\sample.vssx";

Step 2: Load the File Use the Converter class to load the file, preparing it for conversion operations.

using (var converter = new GroupDocs.Conversion.Converter(sourceFilePath))
{
    // The source VSSX file is now loaded and ready.
}

Configure Conversion Options

Overview Set up options to define how your document should be converted into XLS format.

Step 1: Define Output Directory Specify where the converted file will be saved:

var outputFolder = "YOUR_OUTPUT_DIRECTORY";
var outputFile = System.IO.Path.Combine(outputFolder, "vssx-converted-to.xls");

Step 2: Configure Conversion Options Create and configure SpreadsheetConvertOptions to specify XLS as your target format.

var options = new SpreadsheetConvertOptions 
{
    Format = GroupDocs.Conversion.FileTypes.SpreadsheetFileType.Xls // Target format set to XLS.
};

Convert VSSX to XLS

Overview Perform the conversion from a loaded VSSX file to an XLS format using the prepared options.

Step 1: Execute Conversion Use the Convert method on your Converter instance, specifying the output file path and options:

using (var converter = new GroupDocs.Conversion.Converter(sourceFilePath))
{
    var options = new SpreadsheetConvertOptions 
    {
        Format = GroupDocs.Conversion.FileTypes.SpreadsheetFileType.Xls // Set format to XLS.
    };
    
    // Save the converted file at the specified location
    converter.Convert(outputFile, options);
}

Troubleshooting Tips

  • Ensure your VSSX file path is correct and accessible.
  • Verify output directory permissions for writing files.
