Count Duplicates in Array

Posted on by Community Power Pla... Microsoft Employee

This should be simple but I just can't get around it.

I have an array that lists a bunch of users' departments. Only the department names, so it looks like:

Human Resources

Finance

Operations

Human Resources

etc.

Naturally there are duplicates, since some users in this list are from the same department.

I want to count the duplicates.

Basically I want a final list like:

12 users from: Human Resources

1 user from: Operations

2 Users from: Logistics

Thanks @krootz, I replicated your flow, but it seems to be timing out on the Each Dept action, with only 20 items in the array to loop through.

@Anonymous try this flow, very simple. Produces this output, but can easily be adjusted to be formed however you like:
[ { "Department": "HR", "Count": 12 }, { "Department": "Ops", "Count": 1 }, { "Department": "Logistics", "Count": 2 } ]
Fewer steps so less complicated https://ibb.co/54KZH4R (Easier to view on link):
Code for the append to results for you to copy and paste is:
{ "Department": @{item()}, "Count":@{length(body('Filter_array'))} }

See how you get on.

Please...

When you are incrementing the variable under Apply to each, what is the value that you are using?
The if(...)?

Hey

Thanks for your inputs. I tried using your solution here. It is counting but out it repeated. I have a list currently which has 24 entries - 14 of 1 type and 10 of others. I used the above flow to count these from a list - the output is coming as array of 24 items - 14 times for 1 type and 10 times for other - and does show the count. So it looks something like this

Type 1 10
Type 1 10
Type 2 14
Type 1 10
Type 1 10
Type 1 10
Type 1 10
Type 2 14
Type 2 14
Type 2 14

and so on.
How to do i correct to show like below
Type 1 : 14
Type 2 : 10
And maybe in future i will have a type 3 and so on

xpath() can count more efficiently within only one Select 😉
