FAQ
How is the duplicate worksheet named?
The tool uses the original name plus “Copy” and adds a number when needed to keep the name unique.
Does the duplicated sheet keep formulas?
Parsed formulas are retained when supported, but verify references because Excel's full copy engine is not available.
Will macros be preserved in the downloaded workbook?
No guarantee is made for VBA or macro preservation in a newly written XLSX file.
Can I duplicate more than one sheet at once?
This page duplicates the selected sheet once per run.
Does the tool modify the original Excel file?
No. It generates a separate workbook for download.
