FAQs
Does this keep the first version of a repeated line?
Yes. The first occurrence is kept and later duplicates are removed from the output.
What does Ignore case differences do?
It treats lines like Apple and apple as duplicates instead of separate values.
Should I trim lines before checking?
Usually yes. That helps prevent extra spaces from making similar lines look different.
Can I use this for keyword lists or repeated pasted data?
Yes. It works well for simple line-based cleanup across notes, labels, keywords, and exports.
