Remove objects from jArray inside jObject

[SorenB]

Hi

I have a jObject with nested jArray where I need to remove (or keep) specific indexes within.

See example JSON below.

{
    "key1": "abc",
    "key2": "def"
	"forms": [
		{
			"key1": "abc",
			"key2": "def
		},
		{
			"key1": "abc",
			"key2": "def
		},
		{
			"key1": "abc",
			"key2": "def
		},
	]
	"key3": "xyz"
}

I need to keep only one of the entries inside the “forms” jArray - eg. remove index 0 and 2, so the middle one is kept.
The overall structure should remain, but simply remove specific entries from a jArray.

See image for reference.

I know that you can remove specific keys/values from a jArray by using the Invoke Code activity, but I am unsure of how it should be configured, to achieve the desired format.

as far as we have understood you want to remove entries form the JArray, which are JObjects.

So there are two strategies:

• removing items by index (indexes ordered DESC) and the removal one by one

  • JArray.RemoveAt Method

• OR: replace the JArray by a modified JArray, which kept only the needed items

(indexes ordered DESC)

Hahah perfect
Of course I was missing the Reverse to make sure the indexes wouldn’t change when the iteration removes entries.

Thanks @ppr

I ended up with this code:
