Can External Users Access an Excel File Linked to PowerPoint?
Question details
The user wants to know if external recipients can access or edit the original Excel workbook when a chart is linked into a shared PowerPoint presentation.

- Product
- PowerPoint / Excel
- Device & OS
- not provided
- Scenario
- Sharing a PowerPoint presentation containing an Excel chart linked from a local workbook with external users.
- Observed behavior
- The PowerPoint presentation displays the Excel chart, but it is unclear if the source workbook's data is exposed or accessible to external recipients.
Determine whether your Excel chart was 'linked' or 'embedded' into the PowerPoint presentation, as this completely changes how the background data is stored and shared.
Verify and Manage Excel Links in PowerPoint
Check if your Excel chart is linked or embedded to ensure sensitive data is not accidentally shared with external users.
When you link an Excel object, PowerPoint only stores a rendered image of the chart. The actual data remains in your local Excel file. External users cannot access or edit the source workbook unless they also have access to your local drive or shared network.
However, if the chart was embedded rather than linked, a full copy of the workbook is saved inside the PowerPoint file, allowing anyone who receives the presentation to view and edit the underlying data.
Open your PowerPoint presentation and navigate to the slide containing the Excel chart.
Right-click the chart. If you see options like 'Linked Worksheet Object', the file is linked and external users cannot access the source.
To manage all links in the presentation, go to the 'File' tab, click 'Info', look for 'Related Documents' in the bottom right corner, and click 'Edit Links to Files'.
Review the list of linked files. If you want to permanently disconnect the chart from the Excel file to prevent any update prompts, select the link and click 'Break Link'.

Securely Share Presentations with WPS Presentation
WPS Presentation makes it easy to manage linked and embedded Excel charts, ensuring your sensitive data remains private when sharing files with external clients or colleagues.

Frequently Asked Questions
What happens if an external user double-clicks a linked Excel chart in PowerPoint?
If the chart is linked to a local file on your computer, the external user will receive an error message stating that the linked file cannot be found or accessed, keeping your data secure.
How can I share the PowerPoint without losing the chart's appearance but preventing data access?
You can copy the Excel chart and use the 'Paste Special' feature in PowerPoint to paste it as a 'Picture' (JPEG or PNG). This ensures the chart looks identical but contains no underlying data or links.
Can users access the Excel file if it is stored on a shared cloud drive?
Yes, if the source Excel file is stored on a shared network drive, OneDrive, or Google Drive, and the external user has been granted viewing or editing permissions to that specific path, they will be able to open the linked workbook.
