DEVELOPER BENCH
Compile a supplied Draft 7 JSON Schema and validate a supplied JSON value locally with Ajv. Each validation error includes its instance path, keyword, and a human-readable message.
WHAT THIS DOES
Runs entirely in your browser.
/tools/json-schema-validatorjson-schema-validatorv6.0.0LOCAL · LOCAL RUNIMPLEMENTED — This workbench is functional in the current release.Presets for this workbench
No preset yet. A preset stores the values in this form — never the result — and only for workbenches that run entirely in your browser.
Collections
Saved on this device only. Turn on sync to carry them to another device.
BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of json and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
Ajv compiles the pasted local JSON Schema in the browser with all errors enabled. The parsed JSON value is then validated against that local schema.
Boundary: This supports local JSON Schema documents compiled by Ajv’s Draft 7 implementation. Remote `$ref` retrieval, custom formats, application-specific rules, and schema-host security are not supported. Neither input is uploaded.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ

No. This published tool runs locally in your browser. UtilityForge does not send the values entered in this workbench to a server.
No. This workbench runs in the page: JSON Schema (Draft 7), JSON value are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: JSON Schema (Draft 7) (100,000 characters) and JSON value (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
