What this json formatter does
Paste JSON, choose an indentation style and format it into readable structure. You can also minify valid JSON into a compact one-line representation.
Input
Valid JSON text.
Output
Formatted or minified JSON text that can be copied or downloaded.
Example
Turn a compact API response such as {"user":{"id":12,"active":true}} into a readable, indented structure for debugging.
Privacy
Processed locally in your browser — your working input is not uploaded by this tool. The current implementation uses browser APIs for processing. If Tools Brave later adds a server-powered version of this utility, the page will disclose that change before processing begins.
Limitations to know
- The tool only formats syntactically valid JSON.
- JSON comments, trailing commas and JavaScript object syntax are not standard JSON and will fail validation.
- Extremely large pasted datasets can use significant browser memory.
