Consider, for example, selecting a column in an Excel spreadsheet then executing the \\\"Remove Duplicates\\\" Algorithm on it. The intent is to remove rows in that column containing duplicate content. If no duplicate values are present, the information in the column remains unchanged but an Act of Data Transformation was nonetheless performed."@en ;
