How do I create a Master Sheet with formulas that updates other sheets made by copying it, whenever changes are made to the Master Sheet, with the same changes. So if I update a formula, the formula gets updated in every sheet. Very much like how a slide master works.
A scenario: A school enters data through a google form. This is then brought into separate sheets for every class. Say I have 15 classes total. These are then updated by the class teachers with things like say attendance. Now if I change one small thing in one of those class sheets, I have to edit all 15 sheets.
Sometimes Macros work but not always and a new one must be made each time, and then run for each sheet. This is not efficient if you have 63 sheets to update like me.
It feels like one of those things that should already be there! Must be good reasons not to be.
Is there a way to do this either through formulas or through code. I haven't done scripts so would appreciate any help. Thanks in advance.
