How this service works
Validate JSON (with line and column of errors), pretty-print, minify, sort keys, list all paths, show its shape, or extract a value by path like $.items[0].name or $.items[*].
Output
Returns the result of the requested JSON operation: for 'validate', a list of syntax errors with line and column numbers (or confirmation it's valid); for 'pretty', a human-readable indented string; for 'minify', a compact single-line string; for 'sort_keys', JSON with keys sorted alphabetically at every level; for 'paths', a list of all JSONPath expressions present in the document; for 'shape', a structural skeleton showing types; for 'extract', the value(s) matched by the given JSONPath expression.
Example use cases
Debug malformed API response
“I got this JSON back from an API call and something looks wrong — can you validate it and tell me the exact line and column of any errors? Here it is: '{"users":[{"id":1,"name":"Bob"},{"id":2,"name":}'”
Extract nested values with wildcard path
“From this JSON document, extract all product names using the path $.products[*].name — I want to see every item's name in the list.”
Clean up JSON for readability
“Can you pretty-print this minified JSON so I can read it properly? '{"a":1,"b":{"c":2,"d":[3,4,5]}}'”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/util/json?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to inspect, debug, or transform raw JSON strings — especially when you need precise error locations for invalid JSON, or want to extract values without writing custom parsing code. Prefer this over general-purpose code execution when you want a lightweight, stateless JSON utility without spinning up a runtime environment.
Side effects
- Missing 'data' query parameter returns an error
- Invalid operation name returns an error indicating the allowed operations
- 'extract' operation without a 'path' parameter returns an error
- Extremely large JSON payloads may time out or be rejected
- The path expression is syntactically invalid, returning a path parse error
