Need to compare two excel and extract the mismatch data

I have excel Conatant_Sheet1 in that I have two coloumns like signal name and the conatant value.

I have excel 2 name Constant_sheet2 in that again the same data but count is mismatched.

Suppose if in sheet1 we have 10 conatants then there will be 8 conatnts in sheet2 I need to comapre these names along with the values and extarct the names of the signals which are having the differences.

I have attached two sample excel sheets here. Expected results will be like the mismatched data

as Conatant You is added in the sheet2 and value of conatant Barak_obama is chnaged so this is again one mismatch

I want this two misamtched signal names along with their values in the output( whereever in new excel or in matlab variable ..any possible ways)

Mismatched data :

Barak_Obama 4

You 5

Thanks in Advance .... !!!!

Can you show something? Did you try strcmp function?

[Alex Mcaulley]

setxor could be another option. As @darova says show us your code and your specific issues to obtain better answers

I didnt prepared any code. But I serached that it can be done with the help of spreadsheet comapre. So can we trigger spreadsheet compare software through matlab,just like we can trigger excel though matlab
