𧩠JSON Formatter & Validator
Paste JSON and beautify, minify, or validate it in one click. Runs locally, so API data containing keys is safe to paste.
FAQ
How can I tell where a validation error is?
The most common causes are extra or missing commas, full-width quotation marks, a trailing comma at the end, or single quotes used instead of double quotes. Check the location given in the error message.
Can I put comments in JSON?
Standard JSON does not support comments. If you're working with JSONC / JSON5, remove the comments manually before validating.
