Remove text from multiple anki cards at once

Anki Help

Hi, I’ve bought anki cards for specific subject from a person online.

Unfortunately, at the bottom of each card there is a text saying "This card is made/adapted by … " and it’s very annoying.

Is there anyway I can remove from all cards? Cause it’s more than 400 cards to take manually.

You can look for this part in the card template and remove it, which affects all cards. If it is written in every single note, you can remove it with the search and replace function.
