Excel - Combine multiple columns into one column

Question

I have multiple lists that are in separate columns in excel. What I need to do is combine these columns of data into one big column. I do not care if there are duplicate ent

Answer 1

You can combine the columns without using macros. Type the following function in the formula bar:

=IF(ROW()<=COUNTA(A:A),INDEX(A:A,ROW()),IF(ROW()<=COUNTA(A:B),INDEX(B:B,ROW()-COUNTA(A:A)),IF(ROW()>COUNTA(A:C),"",INDEX(C:C,ROW()-COUNTA(A:B)))))

The statement uses 3 IF functions, because it needs to combine 3 columns:

• For column A, the function compares the row number of a cell with the total number of cells in A column that are not empty. If the result is true, the function returns the value of the cell from column A that is at row(). If the result is false, the function moves on to the next IF statement.
• For column B, the function compares the row number of a cell with the total number of cells in A:B range that are not empty. If the result is true, the function returns the value of the first cell that is not empty in column B. If false, the function moves on to the next IF statement.
• For column C, the function compares the row number of a cell with the total number of cells in A:C range that are not empty. If the result is true, the function returns a blank cell and doesn't do any more calculation. If false, the function returns the value of the first cell that is not empty in column C.
