Free JSON Formatter & Validator for QA

Paste a messy API response and get valid, readable JSON you can share with engineering without leaving the browser.

JSON formatter

Live pretty-print, minify, and tree view. Copy a JSONPath from any node. Data stays in this browser.

How QA teams use this

Pretty-print minified gateway or mock-server bodies before writing assertions.
Extract JSON from logs and failed Playwright/Cypress output, then copy a JSONPath from the tree view.
Minify a fixture, drop it into a share URL, and send that link in Slack instead of a screenshot.

Privacy

Formatting, validation, minify, and tree view run in your browser. TestOrbit does not receive the JSON you paste.

Processing happens in the browser. See the privacy policy for cookies and ads.
