Question

I have an Excel sheet which contains data in column - A and Column - B. But I am sure that Column - B contains some data which are also present in Column - A. In such a case I want to remove data from Column - B,which are present in Column - A also.

I tried one approach which gives me the values which are duplicate,putting them in another column.

A1: 1   B1:     C1: 3
A2: 2   B2:     C2: 5
A3: 3   B3:     C3: 8
A4: 4   B4:     C4: 2
A5: 5   B5:     C5: 0

Used the below worksheet function: in B1 =IF(ISERROR(MATCH(A1,$C$1:$C$5,0)),"",A1) and it produced the output as :

A1: 1   B1:     C1: 3
A2: 2   B2: 2   C2: 5
A3: 3   B3: 3   C3: 8
A4: 4   B4:     C4: 2
A5: 5   B5: 5   C5: 0

Not sure how to get the below output :

A1: 1   B1:  8  C1: 3
A2: 2   B2: 10  C2: 5
A3: 3   B3:     C3: 8
A4: 4   B4:     C4: 2
A5: 5   B5:     C5: 0

Can anyone help me for the same?

Answer 1

Type this in B1 and autofill down: =IF(ISERROR(VLOOKUP(C1,A:A,1,0)),C1,"") – this will return in B all values that are NOT in A. If want opposite – swap C1 and “”.
