My question is:
I've a lot of files, like 30+, that I need to maintain periodically.
My idea was to create a master file, where I will modify formulas only 1 time, and then the formulas will be copied automatically to those files.
How is this possible? I thought about some kind of importrange combination but it doesn't make the formula run, it just imports the "numbers".
Update:
Ok I'll try to make it clear. I've many files that all look the same, as this: https://docs.google.com/spreadsheets/d/1arbr1H5Pt-eye5MBv-RrzMy1hrREY4ZE9SNy6rHYFJE/edit#gid=0 (Master) and this https://docs.google.com/spreadsheets/d/1Hwq826njON8qzCu7siHDNjKLGVXRblFxhwdcN1G_gdo/edit#gid=0 (Slave) In Cell A1, Slave is importing the result of A1 in Master. But what I want to achieve is to import the formula, not the result. So Slave will do exactly what Master do, with is own Data on its column D. , as u could see now it isn't.
If Master A1 Sum D1:D, Slave A1 should do the same with its D1:D but when I decide to write another formula in MasterA1, it should as well change with its own reference in all the slaves
