Best for quick edits, review, and copy-paste workflows.

Output updates while you type, so you can verify changes immediately.

Always validate generated SQL against your schema before execution.

How it works

Paste messy or minified JSON into the input pane. The formatter parses it and outputs properly indented, human-readable JSON.

Features

2-space indentation, proper escaping, and instant validation. Invalid JSON shows a clear error message.

Use cases

Debug API responses, format config files, or prepare JSON for documentation and code reviews.
