What It Does
This tool parses JSON text and re-serializes it with consistent 2-space indentation, making nested objects and arrays easy to read. It also validates the JSON, so any syntax errors (missing commas, unmatched brackets, trailing commas) are caught immediately.
Common Uses
- Debugging API responses that are returned as a single minified line.
- Cleaning up JSON before pasting it into documentation or code review.
- Quickly checking whether a JSON payload is syntactically valid.
