Frequently Asked Questions
Paste your list into the input area (one item per line), then toggle the Sort operation and choose A → Z. The sorted result appears instantly in the output. Click Copy or Download .txt to save your result.
Toggle the Remove Duplicates operation. Choose Exact match to remove lines that are identical, or Case-insensitive to treat "Apple" and "apple" as duplicates. The stats bar shows how many duplicates were removed.
Yes. Toggle as many operations as you want — they apply in a sensible fixed sequence: trim whitespace → remove empty lines → sort → remove duplicates → reverse → filter → find & replace → extract unique → count occurrences → prefix/suffix → number lines → wrap. The output updates live as you toggle each one.
Toggle the Add Prefix / Suffix operation, then type your prefix (before each line) and/or suffix (after each line). For example, prefix "- " converts a plain list into a Markdown bullet list, or suffix "," turns it into a comma-terminated list.
Remove Duplicates keeps one copy of each item (removes the extras). Extract Unique Items is the inverse — it keeps only items that appear exactly once. If an item appears more than once, it is completely removed from the output.
