Question details
The user is encountering a 'Copy and paste overlap' error while attempting to use the What-If Analysis tool in Excel and needs a solution to complete their task.
- Product
- Excel
- Device & OS
- not provided
- Scenario
- Setting up or running a What-If Analysis (such as a Data Table or Scenario Manager) to evaluate different data models.
- Observed behavior
- Excel displays a 'Copy and paste overlap' error message, halting the calculation and preventing the results from being generated.
Create a backup copy of your workbook to safely test structural changes without risking data loss, especially when you need to unmerge cells or move tables.
Verify Cell Ranges and Remove Merged Cells
The most common cause of this error is having overlapping input and output ranges, or the presence of merged cells within the calculation area.
What-If Analysis requires a strictly defined, standard grid to function properly. When destination ranges overlap with source cells or contain merged formatting, Excel cannot paste the calculated results correctly.
Review the cell ranges selected for your What-If Analysis (like the row or column input cells for a Data Table). Ensure that these input cells sit completely outside the range designated for the output results.
Highlight the entire area involved in your analysis. Right-click the selection and click 'Format Cells', then navigate to the 'Alignment' tab.
Uncheck the 'Merge cells' box if it is checked or partially filled, then click 'OK'. Adjust your column widths manually if you need more space for text.
Resolve Excel Table and Protection Conflicts
Existing formatted Excel tables or protected worksheets can block the What-If Analysis tool from outputting data into the designated cells.
Test for Workbook Corruption
If ranges and formatting are correct but the error persists, the specific workbook or an object inside it might be corrupted or conflicting.

Frequently Asked Questions
Why does What-If Analysis show an overlap error when I use a Data Table?
This typically happens when the row input cell or column input cell you specified is located inside the actual data table range itself. Your input cells must be placed completely outside the table's output area.
Can merged cells cause errors in Excel scenarios?
Yes, merged cells disrupt the standard grid layout that Excel relies on to calculate and paste scenario results. You must unmerge any cells in both the input and result ranges before running What-If Analysis.
How do I know if my worksheet is protected and causing this error?
Go to the 'Review' tab on the Excel ribbon. If the button in the Protect group says 'Unprotect Sheet', the worksheet is currently protected. This prevents Excel from overwriting cells with the results of your analysis.
