Posted on by NR-05111501-0

I have a MS Form that I’m using in PowerAutomate and I was wondering what I can do with the below to display the additional options without the brackets around it?
concat('TMII Configuration',
' TMII Test Capability: ',outputs('Get_response_details')?['body/rfaec6e0bffdd40d5b2bfefabde0529fd'],
' TMII Isolation Valve Required: ',outputs('Get_response_details')?['body/rc9875756ebb2463fb1194cc4bc614d4b'],
' TMII Part Evacuation Regulator Required: ',outputs('Get_response_details')?['body/raf6c8fc87bbf42c3af36e0e1d2ece592'],
' TMII # of Sources Required: ',outputs('Get_response_details')?['body/rdc0027a7148e41ea9f511e6700d4c294'],
' TMII Tooling Valves: ',outputs('Get_response_details')?['body/r8a8d0c80ffc7477dafe5145405ea7407'],
' TMII Power Cord: ',outputs('Get_response_details')?['body/r331b9f32554a4a25bf6f1a5f9230ec92'],
' TMII Additional Options: ',outputs('Get_response_details')?['body/r3642652628c144a0a27d0cc90dbcf369'],
' TMII Leak Rate & Test Pressure: ',outputs('Get_response_details')?['body/r9c6204709af745a0baaeb8901720aef0'],
' TMII Additional Notes: ',outputs('Get_response_details')?['body/rdac33cf0570047059a0087aed9753f54'])

There are 2 options available to the user but when the email producing the additional options appear as such:
TMII Additional Options: ["Hard Vacuum Gauge","Purging Clamshell"]

How do I get rid of the [“”] and only show the selected item(s)? Is there an adjustment to the code that I can add just for this situation?

Use join() to convert the array into readable text

Like below :

' TMII Additional Options: ',
join(outputs('Get_response_details')?['body/r3642652628c144a0a27d0cc90dbcf369'], ', ') )

Hi @NR-05111501-0,

The brackets are showing because MS Forms returns multi-select answers as a raw JSON array totally normal but annoying to look at.

For that one field, swap this:

outputs('Get_response_details')?['body/r3642652628c144a0a27d0cc90dbcf369']
With this:
join(json(outputs('Get_response_details')?['body/r3642652628c144a0a27d0cc90dbcf369']), ', ')

That will change ["Hard Vacuum Gauge","Purging Clamshell"] to Hard Vacuum Gauge, Purging Clamshell.
One thing to be aware of — if a user only picks one option, Forms sometimes returns it as plain text instead of an array, which would break the json() part.

To be safe, use this instead:

if(startsWith(outputs('Get_response_details')?['body/r3642652628c144a0a27d0cc90dbcf369'], '['), join(json(outputs('Get_response_details')?['body/r3642652628c144a0a27d0cc90dbcf369']), ', '), outputs('Get_response_details')?['body/r3642652628c144a0a27d0cc90dbcf369'])

It checks whether the value is an array first and handles both cases. Everything else in your concat stays exactly the same.

Valantis-

THANK YOU SO MUCH! that worked and looks great.

Can I also use that for this same issue for a different multiple choice question

Concat is:

concat('Instrument Accessories ', outputs('Get_response_details')?['body/ra350077b3e8047bb83dce15b845b9fb8'])

produces as:

Instrument Accessories
["External Exhaust","Enhanced Fill","Diverter Valve","Remote Start/Stop Buttons","Air Filter Kit","BSPT Adapters","CTS Connects","External Leak - Staubli Tee","I/O Cable"]

Hello @NR-05111501-0,

Yes, you can use the same structure for any other question that has a multiple-choice (multi-select) answer.

For example, using

join(outputs('Get_response_details')?['body/<your-field-id>'], ', ')

Your field ID will look something like r3642652628c144a0a27d0cc90dbcf369.

To get it, copy the question from the Get response details action in Power Automate, paste it into Notepad and extract the ID. Then replace <your-field-id> in the expression. This will turn the array into a clean, comma-separated list without brackets or quotes.

Final example like this after adding the field id:

join(outputs('Get_response_details')?['body/r3642652628c144a0a27d0cc90dbcf369'], ', ')
