Copilot Agent Flow to save MS Form responses

In Copilot Studio / Power Automate (Agent Flow), the key thing to understand is:

Your form responses are now stored as an object with dynamic keys, and you want to extract only the values and store them in a single string variable.

Current Object (What You Have)

Your object variable looks like this:

{
  "rbc2b5586363b4b7f94560a2e66b42e3b": "Test1 936",
  "r7e7f03ffed0248558339580c97960824": "Test2 936"
}

You want a string like:

Test1 936, Test2 936

(or newline-separated, if you prefer)

Solution 1: Convert Object Values ? Array ? String (Recommended)

Step 1: Get values of the object

Use this expression:

values(variables('vFormResponses'))

This converts the object into an array:

[
  "Test1 936",
  "Test2 936"
]

Step 2: Join values into a single string

Use the join() function.

Comma-separated string:

join(values(variables('vFormResponses')), ', ')

New-line separated string:

join(values(variables('vFormResponses')), '\n')

Step 3: Set String Variable

Add Set variable action:

• Name: vResponsesText

• Type: String

• Value (Expression):

join(values(variables('vFormResponses')), ', ')

? Result:

Test1 936, Test2 936

Solution 2: Append Using “Apply to each” (More Control)

Use this if you want formatting per question.

Steps:

1. Initialize a String variable vResponsesText = empty

2. Add Apply to each

   • Input:

     values(variables('vFormResponses'))
     

3. Inside loop ? Append to string variable

   concat(item(), '\n')
   

? Result:

Test1 936
Test2 936

Solution 3: Key + Value (If Needed Later)

If you ever need question ID + answer, use:

variables('vFormResponses')

inside Apply to each over:

keys(variables('vFormResponses'))

Best Practice Recommendation

For dynamic MS Forms with variable questions:

? Remove responder and submitDate (good call)
? Use values() to extract answers
? Use join() for compact storage
? Store as plain text for logging, email, or DB storage

Final Answer (Short)

To save "Test1 936" and "Test2 936" into a string variable, use:

join(values(variables('vFormResponses')), ', ')
