What is the easiest way to clean repeated lines?

[toolflora]

If you are working with a long list containing the same information multiple times, you can remove duplicate lines instead of checking every entry manually. Most duplicate-removal tools compare each line and eliminate repeated entries while keeping the unique ones. This is useful for cleaning keyword lists, contact information, product records, or copied text. Depending on the tool, you may also be able to preserve the original order or ignore extra spaces. Always review the cleaned result afterward, especially when working with important business or customer data.
