Quick answer
CSV is a text data format, so it does not preserve a full formatted workbook. Keep an Excel workbook master and export CSV only for the intended data exchange.
Understand the issue
Decide which sheet and fields the receiving system requires. Review identifiers, dates and delimiters in the exported file. Renaming a CSV to an Excel extension cannot recreate formatting or sheets that were not stored in it.
Step-by-step checks
- Save the complete workbook in an appropriate Excel format.
- Export the required active sheet to CSV.
- Reopen the export separately and compare the values with the source.

What the results mean
If the formatted master was overwritten, inspect backups or version history rather than expecting the CSV to contain lost workbook features.
| Stage | Action |
|---|---|
| Start | Save the complete workbook in an appropriate Excel format. |
