Loading and Converting VSTX Files to XLS Format

Overview: This section shows how you can load a VSTX file and convert it into an Excel spreadsheet (.xls format).

Step 1: Define File Paths

First, specify paths for your source VSTX file and output directory.

string documentPath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "sample.vstx"); // Use your actual VSTX filename here
string outputFolder = "YOUR_OUTPUT_DIRECTORY"; // Set your desired output directory path
string outputFile = Path.Combine(outputFolder, "vstx-converted-to.xls"); // Specify the name for the converted file

Step 2: Initialize Converter and Define Options

Create an instance of the Converter class to load your VSTX file. Then define conversion options specific to Excel format.

using (var converter = new GroupDocs.Conversion.Converter(documentPath))
{
    // Define conversion options for XLS format
    SpreadsheetConvertOptions options = new SpreadsheetConvertOptions { Format = GroupDocs.Conversion.FileTypes.SpreadsheetFileType.Xls };
    
    // Perform the conversion and save the output file
    converter.Convert(outputFile, options);
}

Parameters and Methods:

  • Converter: Loads your source document for processing.
  • SpreadsheetConvertOptions: Configures settings specific to Excel conversion.

Troubleshooting Tips

  • Common Issue: File path errors. Ensure paths are correctly specified relative to your project directory.
  • Resolution: Use absolute paths if you encounter issues with relative ones.
