- Choose columns and explicit processing rules. Review the proposed result and warnings.
- Download the chosen result dataset, JSON artifact or report; save a draft to continue later.
What are the limits of JSON Schema Validator?
JSON Schema draft-07; supplied schema stays local. Local # references only, no remote references. No coercion, defaults or removal of fields. Format checks use Ajv draft-07 defaults. Schemas and data are bounded and processing can be cancelled. Unrecognized schema keywords are rejected. Inputs stay in browser memory. No workbook is created. Table limits: 5 MB total text, 25,000 rows, 64 columns and 200,000 cells; expensive operations have stricter limits. Processing can be cancelled.
