Comparing two data tables

Hi @Pablo_Sanchez

I did what you said in the [invoke code] activity with different method.
You can check the xaml flle on [invoke code].

My way is

  1. use [DataRowComparer] to found if the tow rows are different
  2. to compare the columns of the datarow above to find which pair of cells is unmatched in loop.

@lainh I’m sorry… I don’t have so much time now… so much work to do :disappointed_relieved:

If I have time I will check the .xaml, I hope you will get help before as I will be able to check it

Bests,
Pablo

Dear @Ananthu
I tried to use your Comparison logic.xaml file.However, when process comes to Assign counter=counter+1 I got message:
Object reference not set to an instance of an object. This error usually occurs using a variable with not set value (not initialized).

I will appreciate if you can explain how to fix it.

Hi @Aggi ,
Just initialize the counter variable with 0. That should resolve your issue.
Kindly let me know if you face any other issues.

Thanks and regards,

Hi @Aggi,
The problem with your test1 excel sheet is that it haven’t got any unique element to map across sheets for comparison.

In the attached workflow, I have used the row index as unique element and did the comparison. Kindly let me know if you face any issues.

Hi @shreyaank,
I have verified your work flow. You have to initialize the variable i to 0. If you still have issues, kindly send me the excel sheet so that I could verify.
