Extract JSON string data from variable populated from PowerApps Collection

[Chad_Mitchell]

I have been doing a lot of research and continue to struggle with how to work with data I received from PowerApps.  I had to use JSON to pass a collection with an embedded table to MS Flow.  The data looks like the below screen shot when I receive it in the variable in Flow.  I really just need to get the email address from that string array.  I have tried many iterations of substring, split and other expressions with no luck.  Any idea how I can extract only the email address to be used later in the flow.  There are about 65 items in this list.  The real problem I am having is the "email": being passed with the data due to the embedded table of data in PowerApps.

{
"email": "email address here"
},
{
"email": "email address here"
},

Hi @Chad_Mitchell,

The instance you provided is an array, so you could input it into an Apply to each action to loop through all items, then use the expression:

item()?['email']

to get each email address:

I tried what you suggested.  My problem is the variable I am getting from PowerApps seems to be a string even though it is in the array.  Here is what I got when trying your suggestion.  I tried it using the Variable first and then a compose into the apply to each.  Wonder if I need to convert it to an array first.

@v-litu-msft 

that did it.  I used parse JSON after the variable and then the apply to each you suggested.  I now have all the email addresses.  Just need to get them back in a string so I can send the email.  Thank you.

Hi @Chad_Mitchell,

You could initialize a string variable, then loop through all emails and append them + ";" into the string variable, then you could get a string that only contains emails:
