Remove repeated items from a line-separated list
Paste one item per line, optionally ignore case and surrounding spaces when detecting repeats, and generate the deduplicated list. The first matching occurrence is preserved.
Example and important limitation
For example, clean a list of repeated keywords before importing it into a spreadsheet. Check the case-insensitive option if Apple and apple should count as the same item.
