Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Reneeca Fruge,
Welcome to the Microsoft Community.
I understand that you want to know if adding a shared Excel sheet to OneNote will update it in OneNote after updating Excel.
Based on what you've described, I looked up the support article on this and it seems to be a no-no. You can refer to the details below: Add an Excel spreadsheet to a page - Microsoft Support
I understand that this may cause you inconvenience, as we are not OneNote developers can't be directly involved in the feature design. However, in order to bring this issue to the attention of the development team as soon as possible, we encourage our users to provide feedback through our feedback channel as well. Please click on the link: Ideas · Community (microsoft.com)(English platform) to post, where a dedicated developer will follow and comment on your feedback. After sending your feedback, you can share the feedback link in this forum and I will also contribute by voting for you.
If you have any other questions, please feel free to contact us in the community.
Thank you for your understanding and support.
Best regards
