Looping through parsed JSON to get key and value

[moxiego]

I  have a GET command that returns a JSON response.The next step is Parse JSON. From there, I want to loop through the "key" and "value". The Parsed JSON turns the fields into datapills, which I can pull the value, but I can't get the "key" (label). Is this possible?

Create a Ruby action and use the following code. Create an input called "obj" and use the object data pill. It will output an array of objects with key/value keys that are easier to loop through in a traditional Workato loop.

Ruby code:

obj = input["obj"]
array = [] 

input["obj"].keys.each { | k | 
  array.push({"key": k, "value": obj[k]})
}
  
{output: array}
  

Example input object:

{"one": 1, "two": 2, "three": 3}

Output:

{
	"output": {
		"output": [
			{
				"key": "one",
				"value": 1
			},
			{
				"key": "two",
				"value": 2
			},
			{
				"key": "three",
				"value": 3
			}
		]
	}
}

Thank you! I was able to turn it into python code that worked for me.

def main(input):
data = input.get("jsondata", [])
output_list = []

for item in data:
custom_fields = item.get("custom_fields", {})
for key, value in custom_fields.items():
output_list.append({"key": key, "value": value})

return {'output_q' : output_list}

This is such a useful and common requirement that I really hope Workato can build it into a standard function.  I had to ask for help to do this with Ruby years ago. Surely many customers come across this requirement/shortfall in functionality all the time.

It's a tough choice between this or fixing the "triple click list" bug!
