Is there a way to use Google Apps Script to connect two cells together? For instance, if one cell in a sheet is modified, can it automatically update a corresponding cell in another sheet?
For example, let's say in sheet1 there is a "money spent" value in cell A1, and in sheet2 there is the same "money spent" value in cell B4. I would like to change the value in sheet2.B4 or sheet1.A1, and have both cells stay updated at all times.
I am struggling to figure out how to set up a trigger that could achieve this functionality.
