Are there any differences between Excel Online (Business) And Excel Online for Business Actions in Power Automate?
The difference between "Excel Online (Business)" and "Excel Online for Business" in Power Automate actions is mostly a matter of naming convention rather than functionality.
Historically, Microsoft used "Excel Online for Business" in Power Automate actions to refer to Excel files stored in OneDrive for Business or SharePoint Online. Over time, the name was updated to "Excel Online (Business)" to align with the naming of other services in Power Automate.
So, practically speaking, there’s no difference between the two, and they both work with the same Excel files hosted in OneDrive for Business or SharePoint Online with slight metadata differences.
I believe Microsoft is working on redesigning this user experience to avoid such confusion.
