How to convert TSV to CSV

  1. Add your TSV spreadsheets

    Drop TSV files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. CSV is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab.

  3. Download

    Save the CSV, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The TSV to CSV converter is part of this page and runs inside your browser. Your spreadsheets are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

TSV to CSV: what to expect

TSV is less widely recognised by double-click than CSV or XLSX. CSV is plain text that every spreadsheet, database and script can read. TSV is at home in tabular data whose values contain commas; CSV is the usual choice for moving tabular data between systems.

Only the separator changes, from tabs to commas; a field that contains a comma is quoted.

TSV vs CSV

TSV

TSV spreadsheet

TSV is the same idea as CSV with tabs between values, which avoids quoting problems when the data itself contains commas. It is common in scientific and export tooling.

CSV spreadsheet

CSV is a table written as text: one row per line, values separated by commas. Every spreadsheet and database can import and export it, but it holds one sheet only and no formatting, formulas or data types.

Questions

Are my spreadsheets uploaded anywhere?

No. The TSV to CSV conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting TSV to CSV?

The values are kept. Anything CSV has no way to express, such as formatting, formulas or nesting, is simplified or left out.

Can I convert several TSV files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert TSV to CSV on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the TSV file, press Convert and save the CSV. There is nothing to install.

Is there a file size limit?

Yes. Data files up to 300 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
