Track changes from Excel to Power Bi

Hello,

here I have this problem.

I have an excel sheet with values that can change over the time.

When I refresh the excel sheet, the old values are overwritten and so I get them lost.

I was looking for a way to have a table with the old values stored.

What I would not do is to make this process manual, in other words I would like to keep track of changes automatically.

Not sure is power bi is the right tool to do this.

Thanks in advance for your answer.
