How to use Convert TSV to CSV
- 1. Paste the tab-separated data. Drop the TSV into the input pane. Data copied straight out of Excel, Google Sheets or a database client is usually tab-separated already, so a plain copy-paste from a selection works.
- 2. Review the comma-separated output. Tabs become commas, and any value that contains a comma, a quote or a line break gets wrapped in double quotes automatically so the resulting CSV parses correctly everywhere.
- 3. Copy the CSV. Take the result with the copy button and save it as a .csv or paste it into an upload form. The quoting the tool added means strict parsers will read it back byte for byte.
When to use Convert TSV to CSV
Convert TSV to CSV is mostly about what you copied from a spreadsheet. Selecting cells in Excel or Sheets puts tab-separated text on your clipboard, but the form, API or script on the receiving end wants comma-separated with proper quoting. This tool does that translation and escapes tricky values for you.
- Turning a spreadsheet selection into a CSV upload. A CRM import form only accepts .csv files. Copy the rows from Google Sheets, paste the tab-separated clipboard here, and save the converted output as the file the form wants.
- Converting database client output. psql and mysql clients can emit tab-delimited results. Run the query, paste the output, and get a CSV you can attach to a ticket or hand to an analyst.
- Fixing files a partner sent as .tsv. A data vendor delivers tab-separated files but your ingestion pipeline is hardcoded for commas. Converting here, with quoting handled, beats a fragile sed replacement that corrupts values containing commas.

Frequently asked questions
Is Convert TSV to CSV free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
