About this tool
This JSON to SQL generator turns a JSON array of objects into a ready-to-run INSERT statement. The union of all keys becomes the column list, and each object becomes a row in a multi-row VALUES clause.
You can set the table name and choose a dialect — MySQL uses backtick-quoted identifiers while PostgreSQL and ANSI SQL use double quotes. Strings are safely escaped, numbers and booleans are emitted as literals, and missing values become NULL.
Useful for seeding databases from API samples, building migration fixtures, or quickly loading JSON exports into a SQL table.
The SQL is generated in your browser, so your data is never uploaded and the tool works offline once loaded.
JSON Toolbox processes all data locally in the browser. Nothing is uploaded to a server.
