How to remove characters after a specific character?

[Dianari_45]

Tell me, are there any formulas that can implement this?

Hi, welcome to the board.

This is almost certainly do-able.

Give us more details of what exactly you want to do, with maybe 3 or 4 different examples.
In each case, give us what you're starting with, which is the specific character, and what do you want the results to be.
