Hey there :)
I will jump straight to the point. I understood your requirements to fill in the yellow highlighted column in "matching" sheet. So, firstly if you want me to write a VBA code then unfortunately IOS doesnt support VBA, VBA is only supported by Windows and Macintosh. Secondly, we can accomplish this easily without using VBA code, but by using built in functions which would work fine in IOS excel.
Let me know which of the above options would you like me to build. I look forward to a positive and prompt response from your side.
Regards
Sourabh
