TSV to CSV Converter

TSV to CSV Converter turns tab-separated data — the format you get when you copy cells out of Excel or Google Sheets — into standards-compliant comma-separated values. Any field that contains a comma, quote or line break is automatically quoted so the CSV stays valid.

It all happens in your browser, instantly and privately. Paste tab-separated text and the CSV appears as you type.

    Copy the CSV or download a .csv file ready for import anywhere.

When you need CSV instead of TSV

CSV is the most widely accepted import format on the web: database loaders, analytics tools, e-commerce platforms and APIs almost all accept comma-separated files. Converting your tab-separated export to CSV makes it portable to those systems.

Because copying a selection out of a spreadsheet produces tab-separated text, this tool is the quickest way to turn that clipboard content into a proper CSV file without re-saving the whole workbook.

Correct CSV quoting, automatically

The converter wraps a field in double quotes whenever it contains a comma, a double quote or a line break, and doubles any quotes inside it. That follows the RFC-4180 convention every spreadsheet understands, so your data survives the round trip.

Values are never reformatted: numbers, dates and identifiers (including those with leading zeros) are passed through exactly as written.

Frequently asked questions

What if a value contains a comma?
It is automatically wrapped in double quotes in the CSV output so the comma is treated as part of the value, not a separator.
Can I paste straight from Excel?
Yes. Copying cells from Excel or Google Sheets places tab-separated text on the clipboard — paste it here to get a CSV.
Is the conversion private?
Completely. Everything runs in your browser and no data is sent to a server.
