Concatenate values into a string extracted from a json array via a for loop

[michal.gozdzikiewicz]

Hey, new UiPath learner here.
I am trying to save some values into a string that I extracted from a complex json object and paired using a for loop. No matter what I try, how many variable scopes I change, the output outside of the loop is always the last iteration, I can’t seem to append the results into one string.

The log activity printing finalOutput outputs exactly what I need with each iteration. All I want is to have all these outputs stored in one string variable. Scope of these variables has been changed accordingly.

Hi @michal.gozdzikiewicz,

At the time of every iteration (loop) the data stored in the variable are over-write with the new value. Hence the resulting, last loop value are stored in the variable.

To hold multiple values, you should use Non-Primitive data types such as List, Hash-Set, Dictionary or Data Table.

I suggest you to store the data in DataTable data type so that it is easy accessible to you.

Solution:

1. Use Build Data Table activity with 2 columns and create Data Table variable [before the loop]
   

   

2. Inside the loop use Add Data Row to save all the result inside the loop.
   

   
   
   Code

{labelsTest, valuesTest}

Your process logic look like

This will help you to hold all the data after execution of the loop.

Thanks
