Implementation Guide

Convert VDW to CSV

This feature allows you to convert a Visio Web Drawing (.vdw) into a CSV format, essential for data manipulation and analysis.

Load the VDW File

Start by creating an instance of the Converter class with your source file path. This sets up the file for conversion.

using (var converter = new Converter(sourceVdwPath))
{
    // Conversion process will be defined here
}

Define Conversion Options

Specify that you want to convert your document into a CSV format using SpreadsheetConvertOptions.

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

Execute and Save the Conversion

Perform the conversion and save the output as a CSV file.

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputFolder, "vdw-converted-to.csv");

// Convert and save the output
converter.Convert(outputFile, options);

Troubleshooting Tips

  • Missing Dependencies: Ensure all necessary packages are installed.
  • Path Errors: Double-check your file paths to avoid FileNotFoundException.

Practical Applications

Converting VDW files to CSV can be beneficial in various scenarios:

  1. Data Analysis: Easily analyze Visio data using spreadsheet software.
  2. Integration with Databases: Import converted CSV files into databases for further processing.
  3. Automation Workflows: Incorporate this conversion into automated data workflows.
