Delete Duplicates Domains

What is the Delete Duplicates Domains Tool?

The Delete Duplicates Domains tool is a utility that helps you clean up lists of domain names by removing duplicate entries. It processes a list of domains and returns only the unique ones, eliminating any repetitions.

How Does It Work?

The tool uses JavaScript's Set object, which automatically stores unique values, to process your domain list. When you submit a list of domains, the tool:

1. Splits the input by line breaks to create an array of domains
2. Trims whitespace from each domain
3. Converts all domains to lowercase for case-insensitive comparison
4. Uses a Set to filter out duplicates
5. Converts the Set back to an array and joins with line breaks

The result is a clean list containing only unique domain names.
