Implementation Guide

Overview of HTML to Excel Conversion

This feature allows you to transform an HTML document into a structured Excel spreadsheet, simplifying data extraction and manipulation.

Step 1: Define Output Directory Paths

string outputFolder = Path.Combine(@"YOUR_DOCUMENT_DIRECTORY", "Output");
Directory.CreateDirectory(outputFolder); // Ensure the directory exists

// Convert and save with dynamic paths for flexibility and security
string outputPath = Path.Combine(outputFolder, "output.xlsx");

Step 2: Configure Conversion Options

  • SpreadsheetConvertOptions: Customize options like page count or specific pages.
var convertOptions = new SpreadsheetConvertOptions()
{
    PagesCount = 1 // Convert only the first page if needed
};

Step 3: Execute the Conversion Process

Use Converter.Convert to perform the conversion and handle any exceptions.

try
{
    converter.Convert(outputPath, convertOptions);
}
catch (Exception ex)
{
    Console.WriteLine("An error occurred: " + ex.Message);
}

Troubleshooting Tips:

  • Ensure HTML files are well-formed and accessible.
  • Verify that all necessary permissions for file writing are granted.
