JSON to SQL INSERT Converter
Convert a JSON object or array of objects into a multi-row SQL INSERT statement for PostgreSQL, MySQL, or SQLite.
✓ SQL generated locally — review it before running against a database
How to convert JSON to SQL INSERT
- Paste one JSON object or an array of row objects.
- Enter the destination table name.
- Select PostgreSQL, MySQL, or SQLite.
- Review the columns and values, then copy or download the SQL.
Review SQL before execution
The generator escapes string literals and quotes identifiers for the selected dialect, but it cannot inspect your database schema. Confirm column types, constraints, nested JSON handling, and permissions before running the statement.
Frequently asked questions
What JSON shapes can be converted to SQL?
Use one JSON object for a single row or an array of objects for multiple rows. The union of object keys becomes the column list, and missing values become SQL NULL.
Which SQL dialects are supported?
The generator supports PostgreSQL, MySQL, and SQLite identifier quoting and boolean literals. The output is a standard multi-row INSERT statement.
How are nested objects and arrays handled?
Nested values are serialized as JSON strings. Choose an appropriate JSON, JSONB, or text column in your database and review the generated values before execution.
Is it safe to execute generated SQL automatically?
Always review generated SQL and run it in a transaction or test environment first. This browser tool escapes string literals, but it does not know your schema, constraints, or permissions.
Is my data uploaded?
No. JSON parsing and SQL generation run locally in your browser.
