Logic app loop through all elements on the array and add it to the body/description

Question

Actually I don't know if this will work. But I have long array with a lot of elements, I need to display all element in order on the body/description of Jira ticket without writing it manually (example: outputs('Compose')?[0] outputs('Compose')?[1] outputs('Compose')?[2] ). Is there anyway to do it using loop? or any other method?

Note: I don't want it to be as paragraph I need it the same as the array listed.

Example array:

[ 'first element', 'second element', 'third element', ]

printed/displayed format:

first element

second element

third element

---

I tried using loop but don't understand it.

please consider that I'm new to the Logic App or any other technologies with the same idea

Answer 1

There are ways which we can perform data operations such as:

• Line by line
• Spaces

Option 1: Line by line

Firstly, I have initialized a variable as below:

Then used Join (Data Operations) as below:

(here I just clicked Enter in Join with )

Output:

Code view:

{
    "definition": {
        "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
        "actions": {
            "Initialize_variable": {
                "inputs": {
                    "variables": [
                        {
                            "name": "emo",
                            "type": "array",
                            "value": [
                                "rithwik",
                                "bojja",
                                "chotu"
                            ]
                        }
                    ]
                },
                "runAfter": {},
                "type": "InitializeVariable"
            },
            "Join": {
                "inputs": {
                    "from": "@variables('emo')",
                    "joinWith": "\n"
                },
                "runAfter": {
                    "Initialize_variable": [
                        "Succeeded"
                    ]
                },
                "type": "Join"
            }
        },
        "contentVersion": "1.0.0.0",
        "outputs": {},
        "parameters": {},
        "triggers": {
            "manual": {
                "inputs": {
                    "schema": {}
                },
                "kind": "Http",
                "type": "Request"
            }
        }
    },
    "parameters": {}
}

So now you can use the output of Join(body('Join')

Option 2: Spaces

If you keep space in Join you will get ouput as below:

Output:

    "definition": {
        "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",

            "Initialize_variable": {
                "inputs": {
                    "variables": [
                        {

                            "value": [

                        }
                    ]
                },

                    "from": "@variables('emo')",
