loop through json values and perfrom an action on each loop count

I don't think this is a "sample code" scenario as I believe (from what I've understood so far) that this is probably a combination of a User Interface AND a Process Model and may well involve a Record type...so we're headed towards a full Application which I can't just provide a sample of. Are you able to articulate the requirements with more precision? Who needs to do what and why? What's the trigger for the scenario? What is the outcome? And what needs to happen in between?

Ok. So now I don't understand why you're having to deal with JSON? If you're selecting one or more 'Approvers' (and you can implement this using the User Picker object, or a drop-down built form a list of Users) then you can pass this list to the Process as an array of Users. Where does the JSON come into the design?

Hi Stewart, my req is , I have a form where the user can add multiple approver, so once they add the approvers and hit submit(I have used grid layout for this), now in the process, it has to send a task to all the approvers in the grid layout.

Hi Vineeth - still not entirely clear what you want to achieve...but if you want to assign Tasks to Users based upon data, you'll want to make the Assignments in a Process and THEN display the data in a Grid, not the other way around.

Hi Stewart, thanks for the reply, the thing is , am trying to populate the grid(done), now getting the data from the grid in for loop, so that i can assign a task to all user is the Grid column individually

Hi Vineeth - we probably need a little bit more information on exactly what you're trying to achieve. Off the top of my head, you could transform the JSON into a an equivalent CDT - using a!fromJson() - and then use a!forEach() to process the array of items...but without more detail I'm applying some significant guesswork here...
