Bulk vouchers verify

[Snailkhan]

Hi
Is there a script or something using which I can verify all the generated vouchers and see their status if they are used, available, or invalid.
I have some vouchers in the list that spit out invalid magic typo error.

To avoid any inconvenience caused by handling invalid voucher I need to remove them from the list from which it's being handled out to guests.

Regards
