JSON to SQL INSERT
Turn a JSON array into CREATE TABLE and INSERT statements for PostgreSQL, MySQL or SQL Server. Free and private: runs in your browser.
Paste an array of objects to get SQL with properly quoted identifiers and escaped values.
Runs entirely in your browser. Nothing you paste is uploaded or stored.
Use cases
- Move data between APIs, config files and databases.
- Bootstrap models from a sample API response.
- Save time on repetitive hand-written boilerplate.
Frequently asked questions
Is the output safe from SQL injection?
Values are escaped for a one-off load script. In application code, always use parameterised queries instead of building SQL strings.
Is the JSON to SQL INSERT free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Should I use the generated output as-is?
Treat it as a strong starting point. Types are inferred from your sample, so review nullability, naming and edge cases before committing it.
