How to use the JSON Formatter tool
- Paste your JSON.
- Click Format to pretty-print it or Minify to compress it.
- If the JSON is invalid, the error and its position are shown so you can fix it.
Readable, valid JSON
APIs and log files often return JSON on a single line. Formatting adds indentation so you can read the structure, while minifying removes whitespace to make payloads smaller. Validation points to the exact place a syntax error occurs.
