I have a requirement to add multiple properties to an array object based on one of the key value of the same array object.

My Input array is below

{
 "body": [
	{
 "Base64Parts": ["Rick"],
 "NoofParts": 1
 },
 {
 "Base64Parts": ["John","Mark","Roy"],
 "NoofParts": 3
 },
	 {
 "Base64Parts": ["Adam","Steve"],
 "NoofParts": 2
 }
 ]
}

Now based on the maximum value of the "NoofParts" key in the object, I would like to add the same number of properties to each object in the array. Here is my output object.

{
 "body": [
	{
 "Base64Parts": ["Rick"],
 "NoofParts": 1,
	 "Part1": "Rick",
	 "Part2": "",
	 "Part3": "",
 },
 {
 "Base64Parts": ["John","Mark","Roy"],
 "NoofParts": 3,
	 "Part1": "John",
	 "Part2": "Mark",
	 "Part3": "Roy",
 },
	 {
 "Base64Parts": ["Adam","Steve"],
 "NoofParts": 2,
	 "Part1": "Adam",
	 "Part2": "Steve",
	 "Part3": "",
 }
 ]
}

Please advise. I am looking out for ways without using nested apply to each.

Thanks and Regards,

Ramesh Mukka

I was able to get it done with the help of parent-child flows if not Nested Apply to each. It is reasonably fast for as far as 1000 rows I ran. Here are flow snapshots if that can help someone.

Parent Flow

Child Flow
