What it does
TXT Processor is a free browser suite for text and CSV-list operations, including matches, differences, sorting, repeated lines and delimiter-based line breaks.
Choose Find CSV Difference or Find CSV Matches when the question is which entries two lists share or omit. For a single pasted block, sorting, duplicate removal and empty-line cleanup prepare the list for reuse; first-X-character trimming and frequency summaries answer other focused questions. Each processor follows a paste, run and copy workflow. TXT Processor is free without signup, and the publisher says its text utilities run locally in the browser.
