How are strings and quotes escaped?

Single quotes inside string values are doubled, which is the standard SQL escaping, so the generated statements are safe to run as written.

What if some objects are missing keys?

The generator builds the column list from the union of all keys, and any object missing a key gets NULL for that column so every row stays aligned.

Is my JSON uploaded anywhere?

No. The conversion runs entirely in your browser with JavaScript, so your data never leaves your device.

JSON to SQL INSERT Generator

Convert JSON to SQL INSERT statements

Paste a JSON array of objects and get one SQL INSERT statement per row, ready to paste into psql, the MySQL client or SQL Server. Choose your dialect to get the right identifier quoting, and missing keys are filled with NULL so sparse data still lines up to the right columns. Booleans become TRUE / FALSE and numbers stay unquoted.

Everything runs locally in your browser — nothing is uploaded, which makes it safe for confidential data and exports.
