How to convert HTML to Excel

Convert HTML (or MHTML) to Excel Formats

The Sheetize HTML Converter makes it easy to turn web‑page markup into a fully‑featured Excel workbook. Whether your source is a plain HTML file, an MHTML archive, or an HTML string, you can output to any of the supported spreadsheet types:

When to Use This Conversion

  • Generate printable reports from web dashboards.
  • Preserve the visual layout of a web page for offline distribution.
  • Feed HTML‑based data into downstream Excel‑centric workflows (pivot tables, macros, charting).

Step‑by‑Step Guide

  1. Create the converter instance
var converter = new HtmlConverter();
  1. Define loading options (HTML / MHTML)
var load = new LoadOptions {
InputFile = @"C:\Docs\report.html" // or .mhtml
};
  1. Choose the Excel save options – pick the file format you need.
var save = new SaveOptions {
OutputFile = @"C:\Docs\report.xlsx"
// can be .xlsb, .xlsm, .csv, .json, …
// optional: SaveFormat = FileFormatType.Xlsx,
};
  1. Run the conversion
HtmlConverter.Process(load, save);

Full Example – HTML → XLSX 

using Sheetize;
var loadOptions = new LoadOptions {
InputFile = @"D:\Web\Invoice.html"
};

var saveOptions = new SaveOptions {
OutputFile = @"D:\Export\Invoice.xlsx"
};

HtmlConverter.Process(loadOptions, saveOptions);

Advanced Tips

  • Multiple outputs – run the same load options with different SaveOptions objects to produce XLSX and CSV in one pass.

Summary

With a single API call you can transform any HTML or MHTML document into XLSX or any other spreadsheet, data‑exchange or ebook format supported by Sheetize. This bridges the gap between web content and Excel‑centric business processes, giving you the flexibility to move data wherever it’s needed.
