CSV to JSON FAQ

Is this CSV to JSON converter free?

Yes, with no account and no limits beyond your device’s memory.

Is my CSV uploaded?

No. It is converted in your browser tab and never leaves your device.

Are leading zeros kept?

Yes. Values such as 007 or 1.10 stay text, so ZIP codes and IDs aren’t changed. Only values that print back identically become numbers.

What about repeated column names?

They get a number (name_2) so no column is lost, and you are told.
