Delete Duplicate List Values Step

The Delete Duplicate List Values step gets rid of all duplicate entries in a list variable. This helps you make a clean list of unique values.

How to Use Delete Duplicate List Values

Add this step to your process to clean up a list by removing any repeated values.

Step 1: Add the Step

1. Drag and drop the Delete Duplicate List Values step into your process.
2. (Optional) In the Step Name field, type a custom name for the step.

Step 2: Set Up Input Parameters

1. For Source list variable, pick an existing list variable that has the values you want to clean.
2. If your source list variable is a ListOfString data type, you will see the Ignore case toggle:
   • Set to T (True) to ignore whether letters are capitalized when checking for duplicates (for example, "Apple" and "apple" count as the same). This is the default setting.
   • Set to F (False) to treat "Apple" and "apple" as different values.

Step 3: Set Up Output Parameters

1. For Destination list variable, pick an existing list variable or make a new one. This variable will hold the list with all duplicate values removed.
2. For Element count destination variable, pick an existing integer variable or make a new one. This variable will hold the total number of unique items in the destination list.
3. For Deleted count, pick an existing integer variable or make a new one. This variable will hold the total number of duplicate items that were removed.
