Column Swapper and Reorderer

Enter the column positions in your desired order, separated by commas. If you want columns 3, 1, 2 (move third column to first), enter "3,1,2". Column numbers start at 1 for the first column.

Yes, simply don't include unwanted column numbers. If you have 5 columns but only want columns 1, 3, and 5, enter "1,3,5". The output will only contain those columns in that order.

To swap columns 2 and 3 in a 4-column file, enter "1,3,2,4". This keeps columns 1 and 4 in place while swapping 2 and 3. List all columns with the two you want swapped in exchanged positions.

Yes, header rows are reordered along with the data. You can also choose to reference columns by header name instead of position number, making complex reordering more intuitive.

Yes, include a column number multiple times to duplicate it. "1,2,1,3" outputs column 1, then 2, then 1 again, then 3. This is useful when you need the same data in multiple positions.
