When a row is added in this case from a (Zapier into a Google sheet, the formula in a cell not used by the incoming data is deleted.

How can I retain/protect the original formula in column AE being =IF( $Y:$Y ,,$C:$C) or automatically update it from the previous row, when the zap inserts a new row?

You need to drop your IF formula ( =IF( $Y:$Y ,,$C:$C) ) and use ARRAYFORMULA variant:

={"arrayformula here"; ARRAYFORMULA(IF($Y2:$Y, , $C2:$C))}

  • That is awesome... it works perfectly, much appreciated...
