How do I properly extract/convert JSON data into objects? - azure-logic-apps

Question

I have structure below coming via webhook and I'm having trouble understanding if there is built in action in Logic App to get nicely formatted object array of rows which is inside table, where each item will have name and associated value with it.
"SearchResults": {
"tables": [
{
"name": "PrimaryResult",
"columns": [
{
"name": "TimeGenerated",
"type": "datetime"
},
{
"name": "ResourceGroup",
"type": "string"
},
{
"name": "ActivityStatusValue",
"type": "string"
},
{
"name": "d_resource",
"type": "dynamic"
},
{
"name": "c_title",
"type": "dynamic"
},
{
"name": "c_details",
"type": "dynamic"
}
],
"rows": [
[
"2020-06-18T16:30:07.89Z",
"USEASTPROD",
"Updated",
"aueglbwvhypap07",
"Remote disk disconnected",
"We're sorry, your virtual machine is unavailable because of connectivity loss to the remote disk. An unexpected problem is preventing us from automatically recovering your virtual machine."
],
[
"2020-06-18T16:30:07.89Z",
"USEASTPROD",
"Updated1",
"agggggypap07",
"Remote disk disconnected",
"We're sorry, your virtual machine is unavailable because of connectivity loss to the remote disk. An unexpected problem is preventing us from automatically recovering your virtual machine."
]
]
}
]
}
I'd like it to be an array where columns are entity name and each value from rows is it's value like below
"rows": [
[
"timeGenerated" :"2020-06-18T16:30:07.89Z",
"ResourceGroup": "USEASTPROD",
"ActivityStatusValue":"Updated",
"d_resource" : "aueglbwvhypap07",
"c_title" : "Remote disk disconnected",
"c_details": "We're sorry, your virtual machine is unavailable because of connectivity loss to the remote disk. An unexpected problem is preventing us from automatically recovering your virtual machine."
],
[
"timeGenerated" :"2020-06-18T16:30:07.89Z",
"ResourceGroup": "USEASTPROD",
"ActivityStatusValue":"Updated1",
"d_resource" : "agggggypap07",
"c_title" : "Remote disk disconnected",
"c_details": "We're sorry, your virtual machine is unavailable because of connectivity loss to the remote disk. An unexpected problem is preventing us from automatically recovering your virtual machine."
]
]

For this requirement, we can just use liquid with integration account in logic app to implement it. Please refer to the steps below:
1. We need to create an integration account on azure portal first and link it to your logic app. You can refer to this tutorial.
2. In my logic app, I initialize a variable and store your data(add a {} around the data) to simulate your situation.
3. Then use "Parse JSON" action to parse the string above.
4. Create a liquid map in local (I named it as testRow.liquid) with the code below:
{% assign rows = content.SearchResults.tables[0].rows %}
{
"rows": [
{% for item in rows %}
{
"timeGenerated": "{{item[0]}}",
"ResourceGroup": "{{item[1]}}",
"ActivityStatusValue": "{{item[2]}}",
"d_resource": "{{item[3]}}",
"c_title": "{{item[4]}}",
"c_details": "{{item[5]}}"
},
{% endfor %}
]
}
Upload the liquid map(testRow.liquid) to your integration account, for this step you can refer to this tutorial.
5. Then use "Transform JSON to JSON" action", choose the Body from "Parse JSON" action above and use the map which you upload.
6. After running the logic app, we can get the result as below:
The whole result json is:
{
"rows": [
{
"timeGenerated": "6/18/2020 4:30:07 PM",
"ResourceGroup": "USEASTPROD",
"ActivityStatusValue": "Updated",
"d_resource": "aueglbwvhypap07",
"c_title": "Remote disk disconnected",
"c_details": "We're sorry, your virtual machine is unavailable because of connectivity loss to the remote disk. An unexpected problem is preventing us from automatically recovering your virtual machine."
},
{
"timeGenerated": "6/18/2020 4:30:07 PM",
"ResourceGroup": "USEASTPROD",
"ActivityStatusValue": "Updated1",
"d_resource": "agggggypap07",
"c_title": "Remote disk disconnected",
"c_details": "We're sorry, your virtual machine is unavailable because of connectivity loss to the remote disk. An unexpected problem is preventing us from automatically recovering your virtual machine."
}
]
}
By the way:
The format of the sample you provided is invalid in json, we must use {} instead of [] in each of the item.
In liquid map, it will convert your datetime to another format automatically.
Hope it helps~
