Format, validate, compare, and explore your data — instantly, in your browser. Private by default. Starting with JSON.
JSON Formatter
Paste messy JSON and beautify it instantly with clean, configurable indentation. Everything runs locally in your browser — your data never leaves your device.
JSON Validator
Check that your JSON is well-formed and, optionally, that it conforms to a JSON Schema. Errors point to the exact line and column.
JSON Compare
Paste two JSON documents to see exactly what changed — added, removed, and updated values, by path. Comparison runs in your browser.
JSON Viewer
Explore JSON as a collapsible tree or table. Expand, collapse, and search through deeply nested structures with ease.
JSON Minify
Compress JSON by stripping all insignificant whitespace. Smaller payloads for faster APIs and cheaper storage.
JSON Repair
Turn broken or relaxed JSON into valid JSON. We fix single quotes, unquoted keys, trailing commas, comments, and more.
