Compare two excel sheet and calculate how many rows are matching

[Anonymous]

Hi

I have 2 excel sources and data is as below. I want to check for each combination of App and Columns in Excel 1 matches with the combination in Excel 2 and come up with a table which show how many combinations are aligned.  

In this e.g. App A1 has 3 columns and they match with the 3 columns in Excel 2. But for App A2, C4 has a match but C5 doesnt have one. So App A1 is aligned 100%, 3 out of 3 are matching and A2 should be 50% as 1 out 2 match.

Please suggest how this can be accomplished? Thanks.

Excel 1			Excel 2
App	Columns			App	Columns
A1	C1			A1	C1
A1	C2			A1	C2
A1	C3			A1	C3
A2	C4			A2	C4
A2	C5			A2	C6

App	% of Columns Aligned?
A1	100
A2	50

Hi @amitchandak - the solution worked fine, now got slightly different requirement. There can be Apps with '_Test', but this wont be available in excel 2. In this case we have to compare A1_Test with A1 and show as 100%. 

I tried to add a new column, trimmed '_Test' part and tried to check with entries in Excel 2. But it is not working as expected, it is considering A1_Test and A1 as A1. Need to display A1 and A1_Test as seperate entries in output. Any suggestions will be highly appreciated.

Thanks.

Excel 1			Excel 2
App	Columns			App	Columns
A1	C1			A1	C1
A1	C2			A1	C2
A1	C3			A1	C3
A2	C4			A2	C4
A2	C5			A2	C6
A1_Test	C1
A1_Test	C2
A1_Test	C3

Expected Output

App	% of Columns Aligned?
A1	100
A2	50
A1_Test	100

@Anonymous , Try a measure like, But for this need to have a common  table with column app, joined to both tables

a measure like

countrows(Table1, [app], [column]) - countrows( except(summarize(Table1,[app], [column]), summarize(Table2,[app], [column]) ))
