Hi there,
I just reviewed your application and it made me confident that I can put your concerns to rest. The solution would be to
develop this SharePoint site and then create a List and upload your Excel data into it because SharePoint uses SQL database so you can't directly connect Excel as a db. Also if you can elaborate that you have SharePoint Online or On-premises and what version of it.
My name is Syed Najamuddin and a Technical Consultant having worked with companies such as Abdul Latif Jameel Motors Ltd., and Al-nahdi Medical Company, Juffali Saudi Arabia.
I have over 26 years of experience in working with SharePoint, Power Apps, Power Automate,Power BI, SQL Server, Excel, and Web Designing with WordPress, HTM, CSS and Adobe Suite.
So please feel free to reach out and don't hesitate to log a call with me. I can also understand Arabic.
Regards,
Syed najamuddin
