About this tool

Infer a starter table definition from a JSON example object. Processing happens locally in your browser, so your input is not sent to a server or included in analytics.

Frequently asked questions

Are inferred types guaranteed to be correct?

No. Types are inferred from sample values and need review against your data and database.

Which SQL dialect is generated?

The generator uses portable type names and basic quoted identifiers; adjust dialect-specific features as needed.

Does it infer constraints?

No. Add keys, nullability, indexes, and constraints based on your requirements.
