How do I convert TSV to CSV?

Paste your TSV into the converter on this page and pick CSV as the output. Conversion happens instantly in your browser — nothing is uploaded. You can also call the free API: POST /api/v1/convert with { from: "tsv", to: "csv", data }.

Is the TSV to CSV converter free?

Yes. The on-page TSV-to-CSV converter is free and runs locally in your browser. The developer API is also free during beta, with a per-call paid tier for bulk and large payloads.

Convert TSV to CSV

Paste your Tab-Separated Values (TSV) and convert it to Comma-Separated Values (CSV) in one click. Runs entirely in your browser — no upload, no signup.

Input (TSV)

id	name	role	active
1	Ada Lovelace	Engineer	true
2	Alan Turing	Researcher	false

Output (CSV)

Convert this via the API (curl)

curl -X POST "https://data.wrapper-agency.com/api/v1/convert" \
  -H "Content-Type: application/json" \
  -d '{"from":"tsv","to":"csv","data":"id\tname\trole\tactive\n1\tAda Lovelace\tEngineer\ttrue\n2\tAlan Turing\tResearcher\tfalse"}'

Free conversion API — no key during beta. POST { from, to, data }, get back the converted string. All conversion runs server-side; nothing is stored.

TSV vs CSV

TSV

Like CSV but tab-delimited — friendlier when your data contains commas.

CSV

A flat, tabular text format. The lingua franca of spreadsheets, exports, and data dumps.

How to convert TSV to CSV

FormatForge parses your TSV into an in-memory data structure, then serializes it as CSV. Numbers, booleans, and null values are preserved, and delimited output is quoted per RFC 4180 so embedded commas, tabs, and newlines stay intact.

Example

TSV in

id	name	role	active
1	Ada Lovelace	Engineer	true
2	Alan Turing	Researcher	false

CSV out

id,name,role,active
1,Ada Lovelace,Engineer,true
2,Alan Turing,Researcher,false

Convert TSV to CSV in code

Send the conversion to the free API and get the result back as a string:

curl -X POST "https://data.wrapper-agency.com/api/v1/convert" \
  -H "Content-Type: application/json" \
  -d '{"from":"tsv","to":"csv","data":"...your TSV as a string..."}'

FAQ

Does converting TSV to CSV change my data?: No — the conversion is structural. Your values are preserved; only the serialization format changes.
Is my data uploaded anywhere?: The on-page converter runs locally in your browser. The API processes your payload server-side and stores nothing.
