Fix Excel for Mac Copy and Paste Problems Caused by Forcepoint
Question details
The user needs to resolve Microsoft Excel for Mac copy and paste failures that occur when Forcepoint DLP or other clipboard/security software conflicts with the macOS clipboard.

- Product
- Microsoft Excel for Mac
- Device & OS
- macOS
- Scenario
- A user is copying and pasting formulas and formatting between cells in Excel for Mac in a managed macOS environment that runs Forcepoint DLP or similar security/clipboard tools.
- Observed behavior
- Excel pastes values without formulas, the copy marquee disappears, Paste Special options are limited, and Format Painter stops working.
Before changing settings, check whether Excel for Mac is on an Office Insider build and identify any Forcepoint DLP, endpoint security, or clipboard utility running on the Mac. If the Mac is managed by an IT department, ask them to confirm policy changes before disabling security tools.
Test and isolate Forcepoint DLP or third-party clipboard interference
Use this first when Excel for Mac pastes values without formulas and you need to confirm whether a security or clipboard utility is blocking normal clipboard behavior.
macOS Office applications use the system clipboard, not an independent Office clipboard. Security tools can intercept, sanitize, or delay clipboard data, which produces exactly these Excel-specific copy and paste symptoms.
Open Finder > Applications > Utilities > Activity Monitor, search for Forcepoint, DLP, Copy'em Paste, CopyClip, CopyPaste Pro, or similar tools, and note what is running.
Contact your IT department and request that Forcepoint DLP be updated or temporarily disabled for a short test, because managed security policies can block Excel from receiving full clipboard contents.
Quit or uninstall any third-party clipboard utility, then restart your Mac and test copying a formula cell in Excel to see whether Paste Special and Format Painter return.
Go to System Settings > Users & Groups, add a new standard user, sign in to that account, open the same workbook in Excel, and repeat the copy and paste action.

Switch from an Office Insider build to a supported production release
Use this when the affected Excel for Mac installation is on the Insider channel and the issue appears after an Office update.
Restart the Mac and launch Excel without additional login items
Use this for quick isolation when copy and paste fails intermittently and you want to rule out temporary clipboard corruption or startup utilities.
Use WPS Office for Mac as a Free Alternative When Excel Clipboard Conflicts Persist
If Microsoft Excel for Mac keeps losing formulas, Paste Special options, and Format Painter because of Forcepoint DLP or clipboard utilities, WPS Office gives you a free, lightweight spreadsheet alternative with full .xlsx compatibility, a familiar interface, and normal macOS clipboard behavior.
- 1. Download WPS Office for Mac: Go to the official WPS website, download the macOS version, open the installer, and drag WPS Office to Applications.
- 2. Open the Excel workbook in WPS Spreadsheets: Launch WPS Office, click Spreadsheets, and open the .xlsx workbook that was experiencing copy and paste problems.
- 3. Copy and paste with formulas and formatting: Select the cells, press Command+C, use Command+V or Paste Special from the Home tab, and confirm formulas and Format Painter behave normally.

Frequently Asked Questions
Why does Excel for Mac paste values but drop formulas when Forcepoint DLP is running?
Forcepoint DLP or a similar security tool can intercept the macOS clipboard before Excel receives the full copied content. The result is often values-only paste, missing Paste Special choices, or a copy marquee that disappears. Updating or temporarily disabling the DLP agent usually confirms the cause.
How do I check whether my Excel for Mac is using an Office Insider build?
Open Excel for Mac, go to Help > Check for Updates or About Excel, and look for the word Insider. In Microsoft AutoUpdate you can clear the Join the Office Insider program option and install a supported production build.
Will testing with a new macOS user account fix the Excel copy and paste problem?
It helps isolate the cause. Go to System Settings > Users & Groups, add a new standard user, sign in, and test Excel. If copy and paste works there, the issue is related to login items, clipboard utilities, or security policies in the original account rather than to Excel alone.
Can WPS Office open my Excel for Mac workbook and keep formulas when copying?
Yes. WPS Office for Mac opens .xlsx workbooks and supports formulas, Paste Special, and Format Painter in a familiar Spreadsheets interface, and it avoids the Forcepoint DLP clipboard conflict because it is a separate Office-compatible application.
