help! I am trying to compare 2 separate files of patient data. I have a
unique identifer in Column E on both files (patient name and date). I would
like to compare the appointment list (patient name and date) to the list I
receive back from the billing company (patient name and date) to make sure
all the patients were billed. If the patient's name on the appointment list
did not appear on the billing list, I would know that person was not billed.
I know this is possible, but can't for the life of me figure out how to do
it. I'm into this problem for 2 full days now!! Any help would be very
appreciated. Thank you, Teena

Hello Teena

You could link those file to an Access mdb...where you could create a
query
which would be a lot easier to manage.

If you want to do it completely in Excel:
Go to your first free column and enter this in row1 (or row2 if row1
are titles):
=IF(E1="","",IF(ISERROR(VLOOKUP(E1,Sheet2!E:E,1,FA LSE)),"Not
Billed","Billed"))

where E1 is the first cell of the column you want to compare.
Sheet2 is the sheet your Data to compare is stored
E:E is the column where you want to compare the data.

After that you can make an autofilter and show all "not billed"
