Format valid JSON for inspection
Paste the response and check braces, arrays and types. A pretty-printer cannot invent missing syntax or repair arbitrary invalid data.

Trace a data problem from input to output.
Use these browser utilities to inspect structured data without running a remote API request. Formatting, transformation and schema validation solve different problems—none guarantees that an external service will accept your payload.
Convert CSV rows to JSON objects
Use a proper header row and inspect quoted fields. Values may remain strings even when they look numeric.
Open free tool →Compare two JSON responses
Find property changes by path, without confusing indentation or object-key order with a meaningful data change.
Open free tool →Generate a starter schema from examples
Infer an initial JSON Schema from a representative object, then manually refine optional properties and data constraints.
Open free tool →Validate against an explicit schema
Check a candidate JSON document against required keys and types; remember that the schema may omit real application rules.
Open free tool →Try a JSONPath expression
Find a nested value with a supported JSONPath path; review matched nodes rather than assuming all path dialects are identical.
Open free tool →Example: why the same response can look different
The objects {"name":"Mira","active":true} and {"active":true,"name":"Mira"} represent the same object properties in a different order. Structural comparison should distinguish that from a genuine change such as replacing true with false.
Format, convert and validate are not interchangeable
Formatting adds readability to valid data; converting changes its representation; validation checks declared constraints. A syntactically valid JSON document can still be incorrect for your API or database.
Privacy reminder
Remove API keys, live JWTs, credentials and confidential customer data from examples, even when a tool describes local browser processing. Review the site's Privacy Policy and your organisation's requirements.
