Multiple Choice data from Microsoft Forms

[McMonty]

Hi,

I have a SharePoint list with data from a Microsoft Forms survey. One of the fields is a multiple choice field where the data looks like this:
["Option 1","Option 2","Option 3"]

I'm not sure if this is an array, but I'm trying to turn the above into the string below:

Option 1; Option 2; Option 3

Any idea how this could be done?

Hey @McMonty 

The following solution works albeit it it way more complex than I'd like!

 1. Create an array of chars which need to be removed from the string: createArray('[',']','"')

 2. Add a variable to store the 'Initial value' I've manually set the value...

 3. Add a new variable to store the changing / new value

4. Add an 'Apply to each loop'

5. Set the 'Output from previous steps' to the array variable created in step #1

6. Add a 'Set Variable action', add the following expression: replace(variables('InitialValue'),item(),'')

 7. Add a 'Set Variable action' to copy the NewValue to the InitialValue variable... you can't self reference in the replace expression 😞

8. Finally... Add a another 'Set Variable' action underneath the 'Apply to each' loop to perform the final replace expression: replace(variables('InitialValue'),',','; ')

 Your Flow config should look like this... a little convoluted but it works!:

Hey @McMonty 

So this was really bugging me yesterday... I thought there must be an easier way! and there is!

I forgot about the 'Join' action... much simpler:

A little bit simpler!

Hi, my only question is where in the previous solution do I add / replace this?

[Jay-Encodian]

Hi @McMonty 

The second post totally replaces the the first post... they are both complete answers that do the same thing in a different way.

The second post is obviously a lot simpler...

All you really need is the 'Join' action passing in your Form data... that's it 🙂

Hi @McMonty,

The output of the Choice type answer for MS Form will be string, so the only way to process the string to you want is some part of @Jay-Encodian's method 1.

You can add the replace function in the right Expression Bar:

You can try this expression, the variables('Choice') is the output of your Choice answer:

replace(replace(replace(replace(variables('Choice'),'[',''),']',''),',',';'),'"','')

Hey@v-litu-msft @McMonty 

To parse the string to an array use the JSON expression:

Expression: json(<formVariable>)

Super simple 🙂

Hi all,

Big thanks to you both!

I created a variable containing the data from the multiple choice field and then used replace to get the string I wanted when creating the SharePoint item.

replace(replace(replace(replace(variables('Choice'),'[',''),']',''),',',';'),'"','')

Hello Everone!

Thank you for solved !

Is it possible to skip lines for each string received from this solution?

How would you format the Body if you wanted the output to be the following?

Option 1

Option 2

Option 3

You can use the following expression in a Compose function: join(outputs('ConvertResponseToJSON'),'<br>')
