Rename unclear headers before any import or app creation.
Separate repeated lists into clean rows instead of merged cells.
Check formula ranges and totals after removing columns.
Hide internal columns before creating public views or forms.

| Date | mixed text | Date column | Review |
Header
Clear headers make imports, formulas and field mapping safer.
Replace shorthand like Mob No or Amt with names users understand.
Amount
Amounts often contain text such as paid, due or adjusted.
Split amount, status and remarks before calculating totals.
Date
Mixed date text breaks filters and monthly summaries.
Normalize date columns before sharing or importing.
Fix My Excel can clean, upgrade and review workbook structure before users download or save a cleaner file. It is most useful when the file has recognizable columns but weak naming, mixed values, broken formulas, duplicate rows or unsafe sharing habits.
Ambiguous business rules, missing values and duplicate customer identities still need user review. A tool can propose a cleaner structure, but only the business owner knows whether two party names are actually the same customer or whether a blank value is intentional.
Clean the workbook first, then create forms, apps, shared views or document output from the cleaner version. If the workbook starts messy, every downstream view and export carries the same confusion into more places.
Every published free format uses clear column names because imports and review steps depend on predictable headers.
WorkbookWise separates cleanup from final approval so the tool does not guess ambiguous business meaning.
The same cleanup principles apply before Use My Data, Forms, Apps, Share Data and Rows to Documents.
