A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
Dear Catherine,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
Per the description shared, I would like to summarize your requirement i.e., you want to import the existing multiple data cubes into the Excel workbook.
If my understanding of your requirement is correct, AFAIK, we can import the data source one by one and I tried to search for a workaround to import the multiple data sources but unluckily I couldn't find any resource or KB to meet your requirement.
In this situation, I suggest you add your valuable idea to the Excel · Feedback Community (microsoft.com) which is the best place to improve Microsoft Products.
In addition, I will keep this thread open so Excel MVPs and experts can share their valuable ideas regarding your requirement.
Thanks for your cooperation.
Sincerely,
Mia | Microsoft Community Moderator
