Hi Pamela,
Thank you for posting your query in our community.
Per your description, my understanding is that you want to insert Excel chart into PowerPoint file and share PPT to others, at the same time, the Excel chart in PPT should be up-to-date.
You can try the following steps:
- Upload the two documents to your OneDrive.
- Sync OneDrive to your local computer via OneDrive client.
- Open these two documents from the local sync folder.
- Copy the chart from Excel file, and paste it as link like below image in PPT.
- In this way, when you open the documents on the desktop client, the linked data is also refreshed automatically. And the data will be synced to cloud(you may need to open the PPT on your side to make sure the chart in it is updated). So the users who opened the shared PPT will also see the latest chart.
Best regards,
Jazlyn
