The "Delete Columns Selectively" command allows the user to delete columns on the basis of a condition defined by the user.
1. Add a "Multiple file manipulation" step.
2. Add a "Delete Columns Selectively" instruction.
3. Define the workbook, worksheet and cell range to be considered by the instruction.
4. Define the condition for deletion. For example, the above instance deletes columns within the chosen cell range if and only if the first row contains nothing for that column.
