FAQ
Questions JSON Schema Validator and Flattener owners ask.
- 01
How does the validation process work?
The validate_json_against_schema capability performs a strict, rule-based check. It verifies that all required properties are present and that every value matches the defined types and regex patterns without any heuristic guessing.
- 02
What is dot notation flattening?
Using flatten_json_structure, the server collapses nested JSON layers into a single-level map. For example, an object with { "user": { "id": 1 } } becomes { "user.id": 1 }.
- 03
Can I extract specific constraints from a schema?
Yes, the summarize_schema_constraints capability scans your schema to provide a concise list of mandatory keys and any regex patterns used for string validation.
