If Excel copy and paste isn't working properly, it can be frustrating—especially when you're in the middle of important work. This issue can happen for several reasons, ranging from simple user errors to deeper software problems. Here’s a breakdown of the most common causes and how to fix them.

1. Formatting or Data Type Mismatches
Sometimes, copy and paste seems broken because the data isn’t appearing as expected—this is often due to formatting issues.
- Example: You copy numbers from a website or another program, and when pasted into Excel, they show up as text (left-aligned) and can't be used in calculations.
-
Solution:
- Use Paste Special → choose Values or Text.
- After pasting, click the small clipboard icon and select "Match Destination Formatting" or "Paste as Number".
- Alternatively, use
=VALUE()
to convert text to numbers.
2. Clipboard or Excel Glitches
Excel and Windows clipboard can occasionally freeze or malfunction.

- Symptoms: Copying highlights cells, but nothing gets pasted. Or the paste option is grayed out.
-
Fixes:
- Restart Excel.
- Press Ctrl Alt Shift F3 (this restarts the clipboard in some Excel versions).
- Try copying a small range of cells (like one cell) to test if the clipboard is working.
- Restart your computer—this often clears temporary glitches.
3. Protected Sheet or Cells
If the worksheet is protected, you won’t be able to paste into locked cells.
- Check: Look at the Review tab → if "Unprotect Sheet" is visible, the sheet is locked.
-
Fix:
- Ask the file owner for the password.
- Or, if it’s your file, go to Review → Unprotect Sheet before pasting.
4. Merged Cells or Size Mismatch
Excel won’t let you paste data if the copied range doesn’t match the destination—especially with merged cells.

- Error message: “The information cannot be pasted because the Copy area and the paste area aren’t the same size and shape.”
-
Solutions:
- Unmerge the destination cells temporarily.
- Copy only the exact number of cells that match the target range.
- Use Paste Special → Skip Blanks or Transpose if needed.
5. Add-ins or Excel in Safe Mode
Sometimes third-party add-ins interfere with normal Excel functions.
-
Test: Open Excel in Safe Mode (hold Ctrl while opening Excel).
- If copy/paste works in Safe Mode, an add-in is likely the culprit.
-
Fix:
- Disable add-ins one by one (File → Options → Add-ins → Manage COM Add-ins).
- Update or remove problematic ones.
6. Corrupted Excel Settings or Installation
In rare cases, Excel’s settings or installation may be corrupted.
-
Try:
- Repair Office: Go to Control Panel → Programs → Microsoft Office → Change → Repair.
- Reset Excel settings by renaming the Excel config folder (usually in
%appdata%\Microsoft\Excel
).
7. Using the Right Shortcut or Method
Make sure you’re not accidentally using the wrong paste option.
- Use Ctrl C to copy, Ctrl V to paste.
- Try Ctrl Alt V for Paste Special to control formatting, values, or formulas.
- Right-click → choose the correct paste icon (e.g., “123” for values, “∑” for formulas).
Basically, most copy-paste issues in Excel aren’t due to a broken feature—they’re caused by mismatched formats, protection, or software hiccups. Try the fixes above in order, and it’ll likely work again. Most of the time, it’s not complicated—just easy to overlook the little details.
