Free Excel (XLSX) to TSV converter

Why convert XLSX to TSV?

People convert XLSX to TSV because an XLSX needs a spreadsheet program, and plenty of systems accept nothing but plain text, while tab characters never clash with the commas inside your data, so TSV survives messy text.

How to convert XLSX to TSV

1. Choose your XLSX file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .tsv. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .xlsx file?

XLSX is the modern Excel workbook: multiple sheets, cell formatting, formulas and dates that know they are dates. It is what most people mean by “a spreadsheet”, and like DOCX it is really a ZIP of XML underneath.

What is a .tsv file?

TSV is CSV with tabs instead of commas, which sidesteps the classic problem of values that themselves contain commas. It is common in bioinformatics, log processing and anywhere data is piped between Unix tools.

What to expect from this conversion

Cell values are carried across exactly as they appear. Formulas become their calculated results, and formats that hold only one table — CSV and TSV — take the first sheet of a multi-sheet workbook. Only cell values cross over, not formulas — what you see in the sheet is what you get.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your XLSX file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about XLSX to TSV

Is this Excel to TSV converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my XLSX file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

Can I convert Excel to TSV online without downloading software?

Yes. This is an online Excel to TSV converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.

What happens to the quality?

Cell values are carried across exactly as they appear. Formulas become their calculated results, and formats that hold only one table — CSV and TSV — take the first sheet of a multi-sheet workbook. Only cell values cross over, not formulas — what you see in the sheet is what you get.

Can I convert several XLSX files at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Can I convert Excel to TSV without Python or a script?

Yes — that is what this page is for. Python does the same job well if you already have it set up and thousands of files to process; for one file, or a handful, the browser is faster than installing anything.

Should I keep the original XLSX file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that an XLSX needs a spreadsheet program, and plenty of systems accept nothing but plain text.
