Hidden profile format

Hidden stores profiles in named groups inside one JSON file. Each profile nests its addresses and card details.

What gets a Hidden import rejected
01The expiry year is four digits.
02Profiles must sit inside a group; a bare list of profiles won't import.

JSON file

One JSON file holds every profile. It isn't meant to be edited by hand.

UK details

Phones are eleven digits starting 07 and postcodes keep their space. Both get checked before conversion.

Card data stays put

The converter works in memory and stores nothing. Your file comes straight back to your browser.
