Remove duplicate lines from text
Paste text with repeated lines and get a cleaned-up version with each line appearing only once. Useful for de-duplicating email lists, log files, keyword lists, CSV columns, and code.
It scans your text line by line and removes any line that has already appeared, leaving one copy of each. A list of 1,000 entries with 300 repeats comes out as 700 unique lines.
No. Your text is processed on the spot to produce the cleaned result and is not saved or logged.
Common uses include cleaning mailing lists, de-duplicating exported data, tidying keyword research lists, and finding unique entries in log files without opening a spreadsheet.
