 In process variable I'm getting it as ""test@test.com","testing@tets.com"" but I want in format of {"test@test.com","testing@tets.com"}. Can someone please help

Replace the code of a!save() in line 150 as below and see if it suits what you are expecting. 
 a!save(ri!FormattedEmails,
 concat("{",joinarray(
 a!forEach(
 items: local!individualEmails,
 expression: char(34) & fv!item & char(34)
 ),
 ","
 ),"}"))

Stefan Helzle · Answer

Do you want this in JSON format? If yes, use toJson() to transform the list in your local!individualEmails in line 150.

Shubham Aware · Answer

Replace your saveInto with: 
 a!save(
ri!FormattedEmails,
local!formattedEmails
) 
 You already built local!formattedEmails correctly at the top.

In an expression you will see an extra " " at beginning and end but when passed into process model to a text type variable the value will be { "test@test.com","test2@test.com"} without the quotes. So save the changes and then check at runtime you will not see any extra quotes.
