Frequently asked questions
How are column types inferred?
Types are derived from the JSON values: numbers, strings, booleans, and dates map to suitable column types, and nested structures suggest related tables.
Does it produce ready-to-run SQL?
It generates a schema you can use as a foundation; review and adjust types, keys, and constraints to fit your specific database engine before running it.
Can it handle nested JSON?
Nested objects and arrays are interpreted into related structures so the schema reflects the shape of your data.
