How to use this tool
- Paste the data and its schema.
- Run to list validation failures with their data paths.
- All schema references must be included locally.
Things to know
- Draft-07 is supported. Remote references and dynamic code expressions are not fetched or executed.
- Schema validation rejects unsafe integers to avoid validating rounded values.
- Each text input accepts up to 5 MiB. Output is limited to 25 MiB and combined text settings to 1 MiB.
- Structured documents accept up to 128 nesting levels and 250,000 values; query and schema modes have additional limits.
- Schemas accept 10,000 values and 64 nesting levels. Validation stops at the first failed branch and may include its parent errors. Large or complex schemas can reach the worker deadline.
