Are my JSON files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.

Is converting JSON to SQL free?

Yes, without a limit on how many files you convert and with no watermark on the result. Files up to 100 MB are covered by the free plan.

Does converting JSON to SQL lose quality?

JSON and SQL describe content in fundamentally different ways, so the conversion is a reconstruction rather than a copy. The result is faithful, but not byte-for-byte equivalent. Nested objects are flattened into columns. Deeply nested data loses its shape.

Do I need to install anything to open SQL files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the SQL afterwards needs whatever software normally handles SQL Insert Statements on your device.

What JSON and SQL are for

The data format of the web. Nested structures, read by every programming language.
