TSV to XLS Converter

Convert TSV files to XLS. Free and without uploading.

This tool converts TSV files to XLS. Tab-separated values.

XLS is the old binary format of Excel 97–2003; older software and some institutions still require it. 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 TSV 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 XLS files.

Are my files uploaded?

No. Your TSV files are converted to XLS inside your browser.
