Compare lines between excel files wiht Power BI

Hello, 

I  found solution. Not the best one but it works for me. 

Will works on it later to improve the solution. 

- I put all files in a folder and I choose it as source

- I create a date table. the relationship is inactive, because I have some issue --> Continue to work on it

- Create several values (is added values, is deleted value, Is in current file, is in previous, is modified, is using relationship) here is a sample of measure

Then I make measure who count row 

added, deleted, current .. like this

Use measure as filters and I have my solution

Thank you for your help.
