API tips

🔌

Paste the raw response body from Postman, curl, browser DevTools, or any API client. The formatter handles minified, escaped, and nested JSON.

🌳

Use the tree view to collapse/expand sections of a large response. Navigate directly to the data you need without scrolling.

🔍

Validate JSON responses before processing them in your code. The formatter shows the exact line and column of any syntax error.

💡

Copy the formatted version to share with teammates or paste into documentation. Readable JSON is significantly easier to review.
