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?

  1. Paste your CSV data into the input box.
  2. Each row is re-joined with tab separators instantly.
  3. 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.

AspectCSV (comma)TSV (tab)
DelimiterComma (,) with quote escapingTab character, no quote escaping needed
Commas in dataMust be wrapped in double quotesFree — tabs rarely appear in values
Excel pasteOften mis-splitsColumn-aligned, pastes cleanly
AmbiguityQuote rules are a common source of bugsSimpler and less ambiguous
Best forGeneral-purpose data exchangeUnix 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.
