Question details
Data entered in one cell is automatically appearing in the exact same cell across multiple other worksheets within the workbook.

- Product
- Excel
- Device & OS
- not provided
- Scenario
- Editing a workbook containing multiple worksheets, such as monthly reports, occasionally when stored on SharePoint.
- Observed behavior
- When typing data into one sheet, the same entries and edits are instantly applied to the corresponding cells on all other selected sheets.
Look at the sheet tabs at the bottom of your Excel window; if multiple tabs are bright white and the word '[Group]' appears in the top title bar, your worksheets are currently grouped together.
Ungroup Sheets via the Right-Click Menu
The most reliable way to stop data from duplicating is to manually ungroup the worksheets using the tab context menu.
When multiple worksheets are selected (grouped), Excel mirrors every keystroke, edit, and format change across all active sheets. Ungrouping them returns the application to its normal single-sheet editing mode.
Look at the bottom left corner of your Excel window where the worksheet names are displayed.
Right-click on any of the currently selected (highlighted) worksheet tabs.
Click 'Ungroup Sheets' from the pop-up menu. The word '[Group]' will disappear from the top title bar, indicating the sheets are separated.

Ungroup by Clicking an Unselected Tab
A quick shortcut to ungroup sheets if you have at least one sheet that is not part of the current group.

Frequently Asked Questions
Why did my worksheets get grouped in the first place?
Worksheets usually get grouped if you accidentally hold down the 'Ctrl' key while clicking different sheet tabs, or if you hold down the 'Shift' key, which selects a continuous range of sheets.
Can I use sheet grouping to my advantage?
Yes. Grouping sheets is a powerful feature when you want to set up identical structures, such as monthly report templates. By grouping them, you can type headings or apply formatting once, and it will update all grouped sheets simultaneously.
Does grouping worksheets also duplicate formatting and deleted data?
Yes. Any action performed while sheets are grouped—including deleting rows, changing cell colors, or adjusting column widths—will be applied to the exact same location on all grouped worksheets.
