Frequently Asked Questions

Is this TSV to Excel converter free?

Yes. The online converter is completely free and needs no account or email.

Is my file uploaded to a server?

No. The conversion runs entirely in your browser, so your TSV file never leaves your device.

Why does my TSV open in one column in Excel?

Excel splits on a comma by default. This tool produces a proper .xlsx workbook with the tabs already turned into columns, so it opens correctly.

Can I convert a large TSV file?

The browser tool handles files up to 10M. For multi-gigabyte files, batch conversion or automation, use the TSV to Excel desktop app (Windows, macOS, Linux).

Need bigger files or batch conversion?

If this service cannot convert your data correctly, or your files are big than 10M, or you want a batch conversion, you can use Data File Converter to Convert TSV to Excel Offline.
