Question details
Users are encountering a size-mismatch error when attempting to paste copied formulas or values into multiple cells, preventing normal clipboard operations.
- Product
- Excel for Mac
- Device & OS
- macOS
- Scenario
- Copying formulas or values from one or more cells and attempting to paste them into a larger selection of destination cells across various workbooks.

Save your current workbook progress and close any background applications to ensure a smooth troubleshooting process.
Restart Excel and Update Your Software
Resolve temporary clipboard glitches and known bugs by restarting the application and installing the latest Microsoft 365 and macOS updates.
Intermittent copy-and-paste errors in Excel for Mac are frequently caused by software bugs introduced in recent updates, or by conflicts between older versions of Office and a newer macOS. Updating your system ensures you have the latest bug fixes from Microsoft and Apple.
Save your work, click on "Excel" in the top menu bar, and select "Quit Excel". Reopen the application to clear temporary clipboard memory.
Open Excel, navigate to the top menu bar, click "Help", and select "Check for Updates". Install any available updates for Microsoft 365.
Click the Apple logo in the top-left corner, go to "System Settings" (or System Preferences), click "General", and select "Software Update". Install any pending macOS updates.
Create a completely new, blank workbook and try copying and pasting data to determine if the issue is isolated to your previous file.
Use Alternative Pasting Methods
Bypass the size mismatch restriction by modifying how you select your destination cells or using Paste Special.

Frequently Asked Questions
Why does Excel say pasted data is not the same size?
This error typically occurs when the size or shape of the area you copied does not perfectly match the size or shape of the destination area you highlighted. Selecting a destination range that isn't an exact multiple of the copied range triggers this warning.
Can a macOS update cause Excel copy and paste issues?
Yes. Compatibility issues between new macOS versions and older builds of Microsoft Excel can sometimes cause temporary clipboard bugs, resulting in unexpected paste errors. Keeping both systems updated usually resolves this.
How do I quickly copy a formula to an entire column without errors?
Instead of copying the cell and selecting the whole column to paste, simply select the cell containing the formula and double-click the small square at the bottom-right corner of the cell (the fill handle). This will automatically fill the formula down the column.
