When I use the formula ?

To check if there are new values for the previous month.


How to use the formula ?

The formula in this topic is with "," so depending of the operating system of your PC, the formula should have ";" instead of ",".


How are the formula ?









I will add 3 formulas, one in the cell C4, one in D4 and one in D5:

  • C4 -> =LOOKUP(2,1/(A:A<>""),A:A)
  • D4 -> =COUNTIF(A:A, G3)
  • D5 -> =IF(COUNTIF(A:A, C2)=D2,"no","yes")
formula excel

After that, I can add my new data. Before to save and close the file, I will copy the cell C4 and D4 and paste them as values in the cell C2.
