Need help writing a formula/code snippet

Hi all

I am creating a flow and its currently getting the first user record based on a list of users/records.

Here is the compose snippet which currently gets the first user id from the list:

first(outputs('List_rows')?['body']?['value'])?['systemuserid']

What I would like to do now is change this snippet so that it gets the records in the list at random and not be the first record all the time.

I have tried using the rand function many different ways but cant get it right.

Does anyone know how to write it correctly? I would really appreciate it!

Thanks in advance all!

Hi @Usernametwice23,

You could combine a rand function with the length of the array and use a skip and a first to get a random item.

Try something like below:

first(skip(outputs('List_rows')?['body']?['value'], rand(0,length(outputs('List_rows')?['body']?['value']))))?['systemuserid']

Re: Need help writing a formula/code snippet

@Usernametwice23 I have a flow that gets 1 random country each day from a SharePoint list for our intranet. The compose action has the following expression:

body('Get_items')?['value'][rand(1,length(body('Get_items')?['value']))]

Hi @RobElliott,

Great to see that also works, that looks a lot simpler compared to what I suggested 😁

Only suggestion I would have would be to start the range with the 0. Otherwise the first country record will always be ignored from the random pick 😉
