Convert XLTX File to HTML

Overview

This feature allows you to convert Excel template files (XLTX) into HTML format for easy web viewing and sharing.

Step-by-Step Implementation

1. Load the Source XLTX File

string inputFilePath = @"path\to\your\xltxfile.xltx";
using (var converter = new Converter(inputFilePath))
{
    // Conversion will occur within this block

3. Perform the Conversion and Save Output

string outputFolder = @"YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputFolder, "xltx-converted-to.html");

converter.Convert(outputFile, options);

Why?: This method performs the conversion, using specified options to generate an HTML file.

Troubleshooting Tips

  • Ensure your input file path is correct.
  • Verify that your output directory exists and has write permissions.

Practical Applications
