Merging Columns in Excel

Question

I have an excel sheet with two columns A and B. I need to merge these columns and have the result be separated by commas. For example:

Column A | Column B
1 2

Would become

Column C

1,2

If possible I would like this to be done with VBA or an excel formula executed by VBA.

Answer 1

This will take an initial range (defined as rng) cycle through all the rows in this range outputting the contents of column A and B in that row to column C in the same row.

set rng = Range(cells(1,1), cells(activesheet.UsedRange.Rows,1))
for each cell in rng
    cell.offset(0,2) = cell & "," & cell.offset(0,1)
next cell

Answer 2

这是一个excel公式

=CONCATENATE(A1,",", B1)

Answer 3

= A1＆“，”＆B1也可以
