I have a rather large spreadsheet that takes a very long time to calculate once the new data is added. One of the many things I need to do is look to see if a unique value in range 1 is also in range 2. If it is, return some data (vlookup), if it's not, then I want a "0", not #NA. My question is, which of these two methods will result in a faster calculation (if at all):
Option 1: Do it in one step
=IF(ISNA(VLOOKUP($A3,LY,3,FALSE)),0,VLOOKUP($A3,LY,3,FALSE))
Or option 2: Do it in two steps:
Column N formula:
=VLOOKUP($A3,LY,3,FALSE)
Column N+1 formula:
=IF(ISNA(Column N value),0,=column N value)
I have many columns of data using formulas in option 1, so if I have coded this badly that could be my problem...
Thank you for your insights!
