Remove Duplicates

Removes duplicates from a list.

Input

Field Definition Type Required

List

A list of objects that contains the duplicates you want to remove.

 List of Objects TRUE

Path

While List is a list of objects, Path is the name of the key that determines whether something is a duplicate or not.

For example, you may want just one customer record per unique email address.

 Text TRUE

Output

Field Definition Type

List No Duplicates

A list of objects with the duplicate items removed.

 List of Objects

To filter out duplicates using more complex criteria than a single value or key, use the Unique Custom function. This function calls a helper flow to determine the value for each item and determines if it's unique or not.

Examples

If the List is 9,80,1,9,20,1 then the returned List No Duplicates is 9, 80, 1, 20. The function returns only one instance of each number. The card doesn't consider the Path value in this example, as there's only one item in each object.

As another example, consider the following elements in a list of defined objects:

Copy 
[
  {
    "name": "Nicole",
    "value": 10
  },
  {
    "name": "Sarah",
    "value": 20
  },
  {
    "name": "Emily",
    "value": 10
  }
]

If the input for the Path is value, then the returned List No Duplicates has only one object with the value of 10:

Copy 
[
  {
    "name": "Nicole",
    "value": 10
  },
  {
    "name": "Sarah",
    "value": 20
  }
]

If the input for the Path is name, then the returned List No Duplicates is unchanged:

Copy 
[
  {
    "name": "Nicole",
    "value": 10
  },
  {
    "name": "Sarah",
    "value": 20
  },
  {
    "name": "Emily",
    "value": 10
  }
]
