Messy CSV to an editable Excel workbook
- Input
- Six synthetic sales rows: padded labels, currency strings, one exact duplicate, a blank value and an invalid revenue value.
- Output
- Five unique records with typed dates and numbers, two review flags, a formula total and the preserved original CSV.
Known revenue reconciles to $2,650.50. Editing one revenue updates the total; missing values stay unavailable. Workbook structure and both sheet previews are checked.
Produced with a spreadsheet authoring library, not a claimed runtime test of every listed XLSX skill. Native Excel was not executed.
