Implementation Guide

Overview of XLSM to CSV Conversion

This feature allows you to transform an Excel Macro-Enabled Spreadsheet into a CSV format, which can be easily processed or transferred between systems.

Step 1: Define Document Paths

Set up your input and output directories:

string inputDocumentPath = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "sample.xlsm");
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputDirectory, "xlsm-converted-to.csv");

Step 2: Load the Source XLSM File

Use GroupDocs.Conversion to load your XLSM file:

using (var converter = new Converter(inputDocumentPath))
{
    // Conversion logic will be implemented here
}

Step 3: Specify CSV Conversion Options

Configure conversion settings for the CSV format:

var options = new SpreadsheetConvertOptions
{
    Format = SpreadsheetFileType.Csv // Set target format to CSV
};

Step 4: Perform the Conversion

Execute the conversion and save the output file:

converter.Convert(outputFile, options);

Troubleshooting Tips

  • Ensure your input paths are correctly specified.
  • Check for proper permissions on directories used for reading and writing files.

Practical Applications
