About TSV to CSV

TSV to CSV turns tab-separated text into comma-separated values. Paste the text, for instance cells copied from Excel, Google Sheets, or LibreOffice, which the clipboard holds as tab-separated lines. A field that starts with a double quote is read the way Excel writes it, so it can hold tabs and line breaks. In the CSV, a value with a comma, a double quote, or a line break is wrapped in double quotes with inner quotes doubled, and rows end with CRLF. There is no file picker: paste the text.

Example

Three tab-separated lines (tabs shown as →), one value with a comma, one with a quote mark, and one quoted over two lines, and the CSV the tool returns:

TSV

name→city→note
Smith, John→Paris→5" screen
Ann→Lyon→"two
lines"

CSV

name,city,note
"Smith, John",Paris,"5"" screen"
Ann,Lyon,"two
lines"

Where your file is processed

The tab-separated text is converted by the page itself in your browser, and nothing you paste is uploaded. The page shows no error message; an unexpected failure, such as copying refused by the browser, is reported to us as error text with the tool name and your browser version, without your data.

Frequently asked questions

Can I paste cells straight from Excel or Google Sheets?

Yes. Copied cells reach the clipboard as tab-separated text; paste them into "TSV input" and click "Convert". A cell that holds a line break arrives in quotes and is kept as one value.

Will commas inside my values split the columns?

No. Any value with a comma, a double quote, or a line break is written in double quotes, with inner quotes doubled, so a value like Smith, John stays in one column when the CSV is opened.

Can I upload a .tsv file?

No. This page has no file picker; open the file in a text editor or spreadsheet, copy its contents, and paste them. For the opposite direction, CSV to TSV does accept files.
