JSONBeauty
Pretty-print and validate any JSON
JSONBeauty pretty-prints and validates any JSON — paste raw or minified text and get a clean, indented version, or a clear error pinpointing where it is malformed.
Paste raw or minified JSON and get a clean, indented version plus a clear error if it is malformed. For developers and API wranglers.
Accepted formats
- Indent 2 spaces
- Error location reported
- Local, no upload
How does JSONBeauty format JSON?
Paste raw or minified JSON and it returns a clean, indented version (2 spaces) you can read. The formatting is the fast fix for unreadable API payloads.
What if the JSON is broken?
It reports a clear error with the error location, so you find the missing brace or comma instead of guessing where the parse failed.
Is my data uploaded?
No. It is safe and processes locally in the browser, so you can paste internal payloads without sending them anywhere.
Who is JSONBeauty for?
It fits developers and API wranglers who handle JSON daily and want a quick format-and-validate pass.
When the output needs a human pass
JSONBeauty does one thing well: Pretty-print and validate any JSON. A passing schema check only proves the data matches the contract you defined. It will not catch wrong business logic or bad data that still fits the shape.
What goes in, what comes out
- Indent 2 spaces
- Error location
- Safe (no upload)
- Copy-ready
