Sort lists, remove repeated lines, clean pasted data, and prepare keywords, filenames, IDs, or simple text lists for reuse.
Line sorting is useful for keyword lists, allowlists, dependency names, logs, product IDs, usernames, and any plain text where one item appears on each line.
Removing duplicate lines can quickly clean copied spreadsheet columns, merged lists, or generated output. Trimming whitespace helps avoid invisible differences that make two lines look the same but compare differently.
Sorting by length is handy for spotting outliers, unusually long values, or very short entries that may need review.
Ignore case affects sorting and duplicate detection while preserving the retained line's original capitalization. Trim lines before deduplication when leading or trailing spaces should not create separate values. Choose Keep order to clean a list without rearranging it, then copy or download the plain-text result.
