For me it work - just tried it.
When the form is empty, it displays ###'s. But when user starts to enter the numbers/text in the form, it is formatted automatically.
Hey @mazo0o0n,
We (NoCode Monkey) just released an Autosave Masked Input that might help you.
You don’t need the submit button because it will submit as soon as click off of the input.
It also can display the 007 like you were wanting. See the demo below.
