About JSON Tools

100% Client-Side & Private: All JSON processing happens locally in your browser. Nothing is sent to any server.

Formatter: Beautify and organize JSON with customizable indentation (2 or 4 spaces, or tabs). Sort keys alphabetically for consistent formatting.

Minifier: Remove all whitespace and formatting to create the smallest possible JSON representation for transmission or storage.

Repair: Automatically fix common JSON syntax errors like missing quotes, trailing commas, or unquoted keys using intelligent parsing.

Validator: Verify JSON syntax and structure. Optionally validate against JSON Schema standards. Get detailed statistics including depth, key count, and size.

Comparator: Compare two JSON objects and visualize differences. Toggle structural comparison to ignore key ordering.

Use Cases: API development, configuration files, data transformation, debugging, code review, documentation, testing.
