Why use TSV instead of CSV?

Tabs rarely appear inside real values, so TSV needs far less quoting than CSV. It pastes straight into spreadsheet cells and is easy to process with command-line tools like cut and awk.

What if a value contains a tab?

That field is wrapped in double quotes, as in CSV, so the columns stay aligned. Values with line breaks are quoted the same way.

Are my files uploaded anywhere?

No. Every live tool on JustYourConvert opens and converts your files inside your browser, on your own device. Nothing is sent to our servers, and the result is saved straight from your browser.

Is JustYourConvert free?

Yes. Every tool is free, with no sign-up, no watermark and no daily limit. Clearly labeled ads keep it that way.

Is there a file size limit?

Only your device's memory. Because the work happens in your browser, very large files can be slow on phones and older computers. Each tool says its practical limit under the drop area.

CSV to TSV: what to know

CSV separates columns with commas, so any value with a comma in it has to be quoted. TSV separates columns with tabs, which almost never appear inside real data, so the result is simpler to paste into a spreadsheet or process line by line with command-line tools.

This converter parses the CSV properly before writing it: quoted fields, doubled quotes, commas and line breaks inside quotes, and comma, semicolon or pipe delimiters are all handled, with the delimiter detected for you. Each row is then written with tabs between the fields. A field is quoted only if it contains a tab, a quote or a line break, so most rows come out with no quotes at all. Blank lines are skipped and rows with too few fields are padded so every row has the same number of columns.

The output uses Windows-style line endings and keeps all text in Unicode. If the CSV has a header row, it stays the first row of the TSV.

Tips for the best result

If a column holds long text with line breaks, those fields will be quoted; some tools need them removed first.
Check the preview to make sure the delimiter was detected correctly.
Save the result with a .tsv or .txt extension, depending on what the receiving tool expects.
