不同工作表上的四列匹配

Question

Is there a way to find if the combination of 4 column cell values has a match with a different sheet's 4 column cell and display true if the match exists using vlookup? If not what would be the best way to deal with this situation?

Answer 1

If you just want to combine the 4 columns and then have true next to them if they match in the other 4 columns you can do:

=A2&B2&C2&D2 in the cells next to each of the 4 columns. In my example I have just had them in the first 4 columns and with a title row in the first row.

Do that for both sets of columns. Drag the formula down to the entire column. Then next to the one you want to find a match next to do =Sheet2!E2=E2

That is assuming that the second set of 4 columns is in sheet2 with the same first 4 columns used. Then it will be true or false if they exist in both.

Answer 2

You don't seem to need to return any value from matching rows, just check for the existence of a four column match. A COUNTIFS function can accomplish this efficiently and without Helper column(s). Any non-zero value can be considered True but if you need to show TRUE on the worksheet, wrap the formula in an AND function.

Example: You want to check columns A, B, C and D from Sheet1 with columns M, N, J and K from Sheet2. In an unused column to the right of the data on Sheet1, use this formula,

=AND(COUNIFS(Sheet2!M:M, A2, Sheet2!N:N, B2, Sheet2!J:J, C2, Sheet2!K:K, D2))

Fill down as necessary. Any four column matches will show TRUE ; non-matching rows will show FALSE .

With some absolute column references, this formula could also be used in a Conditional Formatting rule to highlight matching rows.
