About this tool

Paste any JSON payload — from an API response, a log file or a config — and get a clean, indented version back instantly. Parse errors are reported with the exact line and column so you can find and fix the problem quickly, right in your browser with nothing sent to a server.

Examples

  • {"a":1,"b":[1,2,3]} → formatted with 2-space indent across multiple lines.
