How to achieve: update the Excel table every week, and the corresponding Indesign table is automatic

How to achieve: update the Excel table every week, and the corresponding Indesign table is automatically renewed?
Assuming that I have printed a copy of the user data about several large websites about some large websites around the world every week. I already have a template. I only need to update the Excel table every week, and the table in my ID will be updated.

I used an example. I have forgotten how I got this file, I just remember that the friend seemed to be very busy at the time. Or the matter is very complicated. He only gave me a document and asked me to study, but I have never found ideas.

Someone can analyze me, how does this file change from Excel to XML, and then import the ID, do it be mapped later?

Can anyone tell me what the structure of this table is like in Excel?
What does the standard XML look like?
Because after I exported XML with Indesign reverse, I couldn't see the structure of the XML.
If you can provide files, that's the best.

Thank you very much.
