Finding and counting duplicate lines
This tool groups every line and shows a count — handy for auditing log files, word lists, or CSV data where repeated entries indicate duplicates. Lines are sorted highest-to-lowest frequency so the most common entries surface immediately. To remove duplicates instead of counting them, use Remove Duplicate Lines. For word-level frequency analysis, try the Word Frequency Counter.
