Things to know before you use it

Always review cleaned data before replacing an original workbook, especially when duplicate rows may be legitimate records.

Cleaning is a structural operation

Removing blank rows, duplicate records and stray whitespace can make spreadsheet data easier to filter or import. Those operations should not be confused with validating whether the underlying business values are correct.

A duplicate row may be a mistake or may represent two legitimate events with identical values. Review the cleaned result when duplicates can carry business meaning.

Before you rely on the result

  • Understand what counts as a duplicate.
  • Review leading/trailing spaces in identifiers.
  • Keep an original copy before bulk cleanup.
