Lets say you have an object like so:

{

"Name": "John Doe",

"Age": 30,

"Email": "johndoe@example.com",

"Address": {

"Street": "123 Main St",

"City": "New York",

"ZIP": "10001"

},

"PhoneNumbers": ["123-456-7890", "987-654-3210"],

"IsActive": true

}

In PAD it might look like this in Input Variable:

Then you use the Key name to refer to tha value you want. So the text under the Name column (in my picture they would be: Name, Age, Email, Address, PhoneNumbers, IsActive)

So in my example if you want the Age then use %ObjectVariable['Age']%
If you want to access first Phone number then %ObjectVariable['PhoneNumbers'][0]%

I am not sure what you are asking. Show example screenshot of the data you want to iterate and what value you want to get out of it.

Are you asking that if you had multiple different items in that like this:

{

"Name": "John Doe",

"Age": 30,

"Email": "johndoe@example.com",

"Address": {

"Street": "123 Main St",

"City": "New York",

"ZIP": "10001"

},

"PhoneNumbers": ["123-456-7890", "987-654-3210"],

"IsActive": true

},

{

"Name": "Jane Smith",

"Age": 27,

"Email": "janesmith@example.com",

"Address": {

"Street": "456 Elm St",

"City": "Los Angeles",

"ZIP": "90001"

},

"PhoneNumbers": ["555-123-4567"],

"IsActive": false

},

{

"Name": "Mike Johnson",

"Age": 35,

"Email": "mikejohnson@example.com",

"Address": {

"Street": "789 Oak St",

"City": "Chicago",

"ZIP": "60601"

},

"PhoneNumbers": ["333-789-6543", "222-555-7777"],

"IsActive": true

}

So if I create a custom object from that:

It looks like this:

and if I press "more" it will give the custom object like so:

Then you just put that JSONAsCustomObject inside a for each loop so it loops through them one by one:

I cant figure out a simple way to do that since I don't think they are meant to be looped like that. When ever I use custom objects I will know the names of the keys. Why not just create a list or data table where you add the values to? Those would be easy to loop.

You could create a list that you insert the keys into and then loop that keys list. Then inside the loop you can reference the custom objects key to get the value like so:

If the keys are just 0, 1 , 2 etc you could use LoopIndex but change them to text:
