Duplicate Line Remover & Text Sorter

Fast, In-Browser Duplicate Line Deduplication & Sorting

Clean up noisy log dumps, email subscriber lists, CSV exports, or database identifiers directly on your machine. This tool executes 100% in your browser memory without uploading any proprietary text or credentials to a remote server.

Key Capabilities

• Flexible Output Modes: Extract unique lines, isolate repeat offenders, count occurrences per line with [Nx] counters, or drop any entries that have duplicates.
• Natural & Length Sorting: Organize items with natural alphanumeric awareness (so item2 comes before item10) or sort by string character length.
• Whitespace & Case Normalization: Automatically strip trailing/leading spaces, empty lines, or ignore uppercase/lowercase variations.
