Implementation Guide

With your environment set up, let’s implement the conversion process step-by-step.

Load a VSTM File

Loading a VSTM file involves initializing and preparing it for conversion:

Step 1: Initialize Converter Object

Load your VSTM file by creating an instance of the Converter class. Handle exceptions to troubleshoot efficiently:

try
{
    converter = new GroupDocs.Conversion.Converter(inputFilePath);
}
catch (Exception ex)
{
    Console.WriteLine("Error loading VSTM file: " + ex.Message);
}

Convert VSTM to CSV

Now, convert your loaded VSTM file into a CSV format.

Step 2: Define Output Path and Conversion Options

Specify the output path for the converted file and set up conversion options:

string outputFilePath = Path.Combine("YOUR_OUTPUT_DIRECTORY\
