XLS to HTML Converter

Convert XLS files to HTML. Free and without uploading.

This tool converts XLS files to HTML. XLS is the old binary format of Excel 97–2003; older software and some institutions still require it.

HTML is the format of web pages and opens in any browser. All sheets, numbers and dates are carried over. Some formatting, such as cell colours, may be lost in the target format.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your XLS files, paste them, fetch one from a link, or use "Choose files".
2. The target format is preselected; you can add several files at once.
3. Press "Convert" and download the HTML files.
