How can I turn an array into a single value or a string?

[Catalina2]

So, currently there is no search for 1 user option, but users in plural. Therefore, the outpur is an array of many values, you can limit to 1 but still an array.

I need to look for 3 users, from an excel. One of the fields may be blank. So when I add a Convert to string step, it does so inside 3 boxes of apply to each. The Filter action is also useless since you need to specify the criteria, what if I want to filter only the first matched value? You cannot do that now.
So for a single email I have this nightmare:

Even for the condition when I would like to split if I have a blank value it gives me the "Aplly each" feature in loop.

Is there a way I can delete values from an array and turn it into a single output?

Thank you so much

@Catalina2 ,

You create a string variable and append the values to it in a loop.

Hope that help!

Hi Sudeep! Thanks for your answer! It is quite helpful only that when I apply these string steps they go inside 3 apply to each boxes, related to the 3 "Search for users (V2)" that I have on previous steps.

What fields are you picking? I will try at my end
