JSON to SQL Converter
Turn a JSON array into SQL INSERT statements ready to seed your database. Choose your dialect, batch rows, and include table creation — all entirely in your browser.
JSON input
Generated SQL
🔒 Runs in your browser — nothing is uploaded to a server.
What this tool does
- Generates clean INSERT statements — maps JSON object keys to SQL columns automatically.
- Supports major dialects — PostgreSQL, MySQL, SQLite, and ANSI SQL identifier quoting.
- Batching options — group rows into multi-row INSERT batches for high-speed imports.
- Optional schema creation — infer SQL column types (INT, DECIMAL, VARCHAR, TEXT, BOOLEAN) and include a
CREATE TABLEstatement. - 100% private — conversion runs locally in your browser.
How values are formatted
- Strings and nested objects are properly escaped and single-quoted.
- Numbers and booleans (
true/false) are written as clean SQL literals. - Missing or null properties become
NULL.
