Hi,

Since this is a custom object, it would be more efficient to append the values to a temporary array variable and then use the Length action. First, declare a temporary array variable, and then use the Append to List action to add the values to that temporary array.

If I have answered your question, please mark it as the suggested answer. If you like my response, please give it a Like.

Regards,
Srini

Hi

You can refer the below example:

Power Automate Desktop Code (Copy and paste into your power automate desktop designer):

SET SampleJson TO $'''{ \"configurations\": [ { \"name\": \"Config1\", \"value\": \"Value1\" }, { \"name\": \"Config2\", \"value\": \"Value2\" }, { \"name\": \"Config3\", \"value\": \"Value3\" } ] }''' Variables.ConvertJsonToCustomObject Json: SampleJson CustomObject=> CustomObject SET ConfigCount TO CustomObject.configurations.Count
