About the Excel to HTML Converter
This XLSX to HTML converter turns spreadsheets from XLSX into HTML without installing software or uploading anything. It solves a common problem: XLSX needs a spreadsheet app and is awkward to load into databases or code. Converting to HTML gives you a self-contained web page, ideal for publishing on the web, email newsletters and viewing documents in a browser.
Spreadsheets are read and written with SheetJS, the open-source spreadsheet engine used by thousands of data apps, so every sheet, row and value is handled accurately. Because everything happens on your own device, your spreadsheets are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: every sheet in the workbook is converted; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact; the first row is used as column names, which you can switch off.
How to use the Excel to HTML Converter
- Click "Choose files" or drag your XLSX spreadsheets onto the box. You can add several at once.
- Choose whether the first row holds column names and whether to convert all sheets or only the first.
- Press "Convert to HTML". The conversion runs on your device and shows its progress.
- Download each HTML file, or use "Download all (ZIP)" when you converted several.
- Open the result in every web browser or VS Code to check it; your original XLSX is never changed.
Tips & benchmarks
- The HTML file is self-contained with clean, readable markup and simple styling, and images are embedded inside it.
- Merged cells are unmerged and their value is kept in the first cell, which keeps the data easy to filter and import.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the HTML to a website or government portal.

How do I convert XLSX to HTML?
Click "Choose files", select your XLSX spreadsheets, adjust the options if you want, and press "Convert to HTML". The HTML downloads immediately; with several files you can download everything as one ZIP.
Is this XLSX to HTML converter free and safe?

Are formulas, formatting and all sheets kept?
