I am calling the SP API to get the version history of an item in my list as follows:

 _api/web/lists/getbytitle('@{triggerBody()?['SPListName']}')/items(@{triggerBody()?['SPListID']})/versions?$top=20

I am getting the values and parse them with a JSON parser as explained here,

I can get all the values of the columns of my list without any issue, however I have a multi-choice column which returns the below string as the result of the Parse JSON action

 {"__metadata":{"type":"Collection(Edm.String)"},"results":["Choice 2"]}

if I select two choices in my multi-choice column, I get the below result:

{"__metadata":{"type":"Collection(Edm.String)"},"results":["Choice 1","Choice 3"]}

How can I only get the value in the "results" section as a string such as "Choice 1","Choice 3" rather than the whole metadata string

Updating for [Send a HTTP..] request. Here [results] is an array, and [MyChoice] is also an array.

body('Parse_JSON')?['d']?['results'][1]['MyChoice'][0]['Value']

Here's how I can find individual choice value when retrieving list items using [Get items] -> [Parse JSON] -> [Apply to each]

Here for each item, [MyChoice] is the Property (column name of the multi-value), and [0] is the index of the first value. You can check the length of [MyChoice] and dynamically find each value.

items('Apply_to_each')['MyChoice'][0]['Value']

Updating the answer showing how to dynamically capture values from a multi-value column

Please see the screenshots and explanation below.

Please note that it's very important to analyze the output from [Send an HTTP..] by using a [Compose] action before feeding into [Parse JSON]

  • Thank you, How can I check the length of MyChoice dynamically?, can you show me a code or screenshot to iterate through MyChoice and get each value and append it to an array based on the output of Parse JSON? – Mohsen Sichani Oct 22 '20 at 18:42
  • I am doing it by if(greater(indexof(string(items('Apply_to_each_History_Parse_JSON')?['BudgetSource']),'['),1),replace(replace(replace(string(items('Apply_to_each_History_Parse_JSON')?['BudgetSource']),'{"__metadata":{"type":"Collection(Edm.String)"},"results":[',''),']}',''),'"',''),''), but any better solution? – Mohsen Sichani Oct 22 '20 at 20:01
  • I'm almost done posting the update.. give me a few minutes – Matiur Rahman Oct 22 '20 at 20:21
  • Sure thanks a lot, no rush – Mohsen Sichani Oct 22 '20 at 20:43
  • Update completed. Note that there are two loops, one at the item level and within that the loop for choices of each item. Since you know the length of the [MyChoices][results], you can use [Do Until] loop as well. It depends how you want to use it. But let me know if you have any further questions – Matiur Rahman Oct 22 '20 at 20:57
