Quick Answers
- Why would I need to convert CSV to TSV?
- Many database importers, Unix tools and analytics platforms treat tabs as the standard delimiter. A TSV avoids conflicts when your data itself contains commas.
- Does this tool preserve quoted fields?
- Yes. Values are parsed respecting quotes first, so commas inside quoted fields never split a row incorrectly.
- Is the conversion reversible?
- Yes. Use the TSV to CSV converter to turn the result back into comma-separated data at any time.
How do I use CSV to TSV Converter?
- Paste your CSV data into the input box.
- Each row is re-joined with tab separators instantly.
- Copy the TSV or download it as a .tsv file.
Why use our csv to tsv converter?
Some tools treat tabs as the native delimiter and will garble commas inside quoted fields. This converter parses your CSV properly, respecting quotes, then rebuilds every row with tabs. Fields that themselves contain tabs are normalized so the output stays a valid TSV. All processing is local, so spreadsheets with customer or financial data never touch a server.
CSV vs TSV — delimiter differences
Both formats are delimiter-separated tables. Moving from a comma to a tab separator matters when your values frequently contain commas, such as addresses or sentences.
| Aspect | CSV (comma) | TSV (tab) |
|---|---|---|
| Delimiter | Comma (,) with quote escaping | Tab character, no quote escaping needed |
| Commas in data | Must be wrapped in double quotes | Free — tabs rarely appear in values |
| Excel paste | Often mis-splits | Column-aligned, pastes cleanly |
| Ambiguity | Quote rules are a common source of bugs | Simpler and less ambiguous |
| Best for | General-purpose data exchange | Unix pipelines and clipboard tables |
Preparing a CSV for tools that choke on commas
Some CLI tools, pasteboards and data pipelines split on tabs instead of commas. Converting a CSV to TSV keeps the same rows but uses tab separators, so fields containing commas stay intact.
Input CSV
city,state,population New York,NY,8400000 London,United Kingdom,8900000
Converted TSV
city state population New York NY 8400000 London United Kingdom 8900000
Paste a CSV and export a TSV for command-line tools, clipboard paste into a grid, or pipelines where commas inside values break the parser.
