Compare Spreadsheets to Master Sheet

[jwashburn]

I have a Master sheet that contains products. There are approx 800 lines in this sheet.

I also have 2 other sheets that are basically subsheets of the Master. The California product list has about 400 products in it, the Nevada one approx 500.

As a business rule any product in one of the sublists MUST exist in the master list. I am trying to find an easy way to compare the sub list to the master list so I can make that one of the sublists did not get a product added to them that hasnt been added to the master list.

Can you think of anything in Excel or maybe a third party product that might help

You could use the VLOOKUP function. If the formula returned '#N/A' it could indicate that the Product was not in another sheet.

All three sheets should be sorted alphabetically by Product.

If the field name 'Product' existed in the three sheets, in the same column, say column A;

Master!
one empty column:
=VLOOKUP(A2,California!A2:A401,1,FALSE)

second empty column:
=VLOOKUP(A2,Nevada!A2:A501,1,FALSE)


California!
one empty column:
=VLOOKUP(A2,Master!A2:A801,1,FALSE)


Nevada!
one empty column:
=VLOOKUP(A2,Master!A2:A801,1,FALSE)


Have a great day,
