TSV to XLSX Converter

Convert TSV files to XLSX. Free and without uploading.

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

XLSX is Microsoft Excel’s current workbook format. It holds multiple sheets, formatting and formulas. 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 XLSX files.
