Online Text Deduplication and Sorting Utility

Overview

A comprehensive, browser-based utility designed to clean, format, and optimize plain text. It serves writers, developers, and data analysts by providing an instant way to strip noise from lists, log files, or document drafts without needing server-side processing.

Layout Structure

• Header: Clean, minimalist title.
• Main Interface: A split-screen responsive layout. The left side holds the 'Input Area' (Textarea), and the right side holds the 'Output Area' (Read-only Textarea).
• Control Panel: Positioned between or below the text areas, housing all configuration toggles.
• Footer: Simple links to privacy policy and usage instructions.

Visual Design

• Color Palette: High-contrast neutral tones (slate gray for text, white for background). Action buttons use a distinct, accessible blue (#0066cc) for primary actions and soft red (#cc0000) for clearing.
• Typography: Monospaced fonts for text areas (e.g., 'Courier New', 'Consolas') to ensure readability of list-based data. Sans-serif for UI labels.
• Animations: Subtle fade-in for results, and a brief scale-down effect when clicking buttons to provide haptic-like visual feedback.

Core Features

1. Deduplication Logic:
   • Line-based: Removes exact line duplicates.
   • Word-based: Tokenizes text by delimiters (space, comma, newline) and removes duplicate tokens.
   • Case Sensitivity: Toggle to treat 'Apple' and 'apple' as the same or different.
2. Text Cleaning:
   • Trim Whitespace: Automatically strip leading/trailing whitespace from lines.
   • Remove Empty Lines: Strip blank lines from the final output.
3. Sorting:
   • Alphabetical (A-Z).
   • Reverse Alphabetical (Z-A).
   • Preserve original order (default).
4. Advanced Controls:
   • Custom Delimiters: Allow the user to specify custom characters for splitting text (e.g., ' | ', ';').
   • Regex Mode: Enable advanced users to target specific patterns for removal.
5. Utility Actions:
   • Copy to Clipboard: One-click button with a toast notification ('Copied!').
   • Download as .txt: Save processed data directly as a text file.
   • Live Counter: A status bar showing 'Original count vs. Final count' and the number of duplicates removed.
   • Clear All: Reset both fields instantly.

Interaction Flow

1. User pastes text into the input field.
2. User adjusts settings (e.g., toggle 'Sort Alphabetically', 'Remove Empty Lines').
3. The tool performs the operation in real-time or via a 'Process' button (user preference setting).
4. Output is rendered instantly. The 'Copy' button becomes active.
5. User exports the result or copies it for further use.
