How do I convert YAML to CSV?

Paste your YAML 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: "yaml", to: "csv", data }.

Is the YAML to CSV converter free?

Yes. The on-page YAML-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 YAML to CSV

Paste your YAML Ain't Markup Language (YAML) and convert it to Comma-Separated Values (CSV) in one click. Runs entirely in your browser — no upload, no signup.

Input (YAML)

- id: 1
  name: Ada Lovelace
  role: Engineer
  active: true
- id: 2
  name: Alan Turing
  role: Researcher
  active: 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":"yaml","to":"csv","data":"- id: 1\n  name: Ada Lovelace\n  role: Engineer\n  active: true\n- id: 2\n  name: Alan Turing\n  role: Researcher\n  active: false"}'

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

YAML vs CSV

YAML

An indentation-based, comment-friendly format used heavily for config (Kubernetes, CI, Docker Compose).

CSV

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

How to convert YAML to CSV

FormatForge parses your YAML 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

YAML in

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

CSV out

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

Convert YAML 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":"yaml","to":"csv","data":"...your YAML as a string..."}'

FAQ

Does converting YAML 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.
