About Remove Empty Columns
Remove Empty Columns deletes fields/columns whose values are empty in ALL rows — useful for dropping columns that were never populated after a data import.
The tool checks each column across the whole dataset; if no row has a value for that column, it is removed from every row.
Processed in the browser. For empty rows, see Remove Empty Rows.
