How do I convert TSV to JSON?

Paste your TSV into the converter on this page and pick JSON 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: "json", data }.

Is the TSV to JSON converter free?

Yes. The on-page TSV-to-JSON 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 JSON

Paste your Tab-Separated Values (TSV) and convert it to JavaScript Object Notation (JSON) 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 (JSON)

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":"json","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 JSON

TSV

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

JSON

A lightweight, human-readable data-interchange format. The default for web APIs and config.

How to convert TSV to JSON

FormatForge parses your TSV into an in-memory data structure, then serializes it as JSON. Numbers, booleans, and null values are preserved, and nested structures are mapped to JSON's native shape.

Example

TSV in

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

JSON out

[
  {
    "id": 1,
    "name": "Ada Lovelace",
    "role": "Engineer",
    "active": true
  },
  {
    "id": 2,
    "name": "Alan Turing",
    "role": "Researcher",
    "active": false
  }
]

Convert TSV to JSON 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":"json","data":"...your TSV as a string..."}'

FAQ

Does converting TSV to JSON 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.
