Counting the number of values within a Form multiple answers box

(0) ShareShare
ReportReport
Posted on by

Hi,


I have a MS Form that has a multiple answers box like the one below:

What I'd like to do is could the number of answers that is submitted and output the result as a numeric value I can use later within the flow.  I can see that within Flow the values are separated out and I thought I could use length to calculate but that doesn't appear to be working.

Any thoughts gratefully received.

 

Cheers

Rob

    Hello,

    You can alternatively put an expression:

    if(not(empty(yourFormObj),length(json(yourFormObj)),0)

    @manuelstgomes I think I've got a solution, it's not pretty but it works.

     

    - I split the string using the comma as a delimiter

    - I then use this output and initialise a variable to create an array

    - Finally I use a length expression to count the number of items in the array

    The resulting output from this I can then fire into a SharePoint column

    If anyone has a more elegant solution it be great to see it.

     

    Cheers

    Hi @Rob_CTL 

     

    Try the parse JSON action..

     

    But the issue is that everything is a string in Forms. It sucks I know but we need to deal with that 🙂

    Hi @manuelstgomes 

     

    Thanks for the link.

     

    I can see that the output is formatted in both JSON and a string

    I am thinking there must be a way I can manipulate this data into something that I can count, or maybe I am wishing to much 🙂

     

    Cheers

    Hi @Rob_CTL 

     

    Getting information from Forms is tricky because everything comes in string format. I provide more details in how to take care of these issues in this article I wrote.

    Can you please check if and let me know if you have any questions?
