We have a Forms input:


Using Flow to move the Forms data to Sharepoint Multi Choice field in List


Same issue but hoping there are better ways of doing it now:

Hi @robcarrs 


The issue is that you're passing to SharePoint a "string" that comes from the Form that contains a JSON with an array. Quite tricky, I know, but let's break it down into an example:


The "Create Item" expects something like this:


    "Value": "Option 1"
    "Value": "Option 3"


and you're providing

"Value":"[\"Option 1\",\"Option 3\"]"

You need to convert it to an array of values so that SharePoint can match the items and know what to do with them.


You need to:

  1.  Remove the special characters [," and ]
  2. Create an array
  3. Build a new array with the structure {"Value":"Option 1"}


Here's the full flow:

To remove the characters, use a compose with the following formula:




Then create an array with the elements:



To create the array create an empty array variable. Then do a for each and append to the array with the following formula:


Finally, insert the value in the "Create Item."


You'll get something like this:

I've added a template so that you can import so that you don't need to create everything manually.
