Hello Chintan,
Welcome to chandoo.org forum and we glad to have you here.
I do not understand you your requirement clearly.
It does not matter which side the area column is when you run the sumif formula.
Say your data is as follows from Col A to Col C:
[pre]
Code:
10 A 10
20 C 20
30 F 30
22 A 22
45 A 45
[/pre]
Sumif formula when area is before the amount:
=SUMIF(B1:B5,"A",C1:C5) enter...will give you 77
Sumif formula when area is after the amount(which is your concern I believe):
=SUMIF(B1:B5,"A",A1:A5) enter...will give you 77
So, both the cases you will get the same answer no matter which side your criteria range / sum range is located.
Are you trying to do any lookup to left side? If yes, then INDEX-MATCH or VLOOKUP-CHOOSE functions can be used.
Request you to plz post back in case of any further help is required.
Regards,
Kaushik
