comparing 2 columns
Posted on 2014-09-10
I have got a set of data returned from a query – exported to excel. I have 2 rows of data I need to “compare”, they are called invoice_num and invoice_ID. If a unique invoice_num appears in 20 consecutive rows – there should also be a unique invoice_ID which should also appear in the same 20 rows.
As it stands invoice_num is in column A and invoice_ID is in column B. I presume an additioanl column i.e. Z that has some sort of summary would be fine. An exception would be if you have unique invoice_num but different invoice_ID on different rows, and vice versa.
