Frequently Asked Questions

Which SQL statements are accepted?

Tool currently accepts INSERT statements with explicit columns and VALUES rows. Other SQL commands are not parsed.

Does converter support multiple rows in one INSERT query?

Yes. Multi-row INSERT syntax is supported, and each row becomes one JSON record object.

How are SQL NULL and boolean values handled?

NULL converts to JSON null, and boolean-like values convert to JSON booleans. Numeric values are emitted as numbers.

What happens when column count and value count do not match?

Tool shows parsing error and clears output so you can correct SQL before conversion.

Is conversion performed on server?

No. SQL is processed in browser for quick response and better privacy while transforming data.
