AI Generation Prompt
Free Online Whitespace Remover & Text Formatter
Overview
A high-performance, single-file browser utility designed to clean, normalize, and format text by removing unwanted whitespace. Built for developers, data analysts, and writers who need to sanitize strings quickly without external software.
Core Features
- Trim Leading/Trailing: One-click removal of whitespace from the start and end of the text block.
- Collapse Multi-Spaces: Convert multiple consecutive spaces, tabs, or non-breaking spaces into a single space.
- Normalize Line Breaks: Convert various line ending formats (CRLF, LF) to a uniform standard.
- Total Strip: Remove all whitespace characters, including newlines and tabs, to create a single concatenated string.
- Live Stats: Real-time character, word, and line counting display (Before vs. After).
- One-Click Copy: Dedicated clipboard integration for instant text retrieval.
- Diff Preview: Clear visual distinction between the raw input and cleaned output.
UI/UX Specification
Layout
- Header: Simple, clean application title with a subtitle describing the utility.
- Input Section: A large, resizable textarea for text input.
- Toolbar: A horizontal bar containing buttons with distinct primary/secondary visual hierarchy (e.g., "Trim Text" as Primary, "Reset" as Secondary).
- Output Section: Read-only textarea with a 'Copy to Clipboard' button floating in the top right corner.
Aesthetics & Design
- Color Palette: Pure white background (#FFFFFF), soft slate gray (#F8FAFC) for backgrounds, and a professional primary blue (#2563EB) for interactive elements. Text should use dark slate (#1E293B).
- Typography: Sans-serif, system-ui font stack for maximum legibility (e.g., Inter, system-ui, -apple-system).
- Micro-interactions: Buttons should have subtle scale-down effects on click and a gentle shadow transition on hover. Output text areas should provide feedback (e.g., a momentary "Copied!" tooltip) when clicking the copy button.
Technical Implementation Directives
- Architecture: The entire application must be contained in a single
.htmlfile. CSS and JS must be embedded or linked via CDN. - No Persistent State: This tool runs in a sandboxed environment. Do not use
localStorage,sessionStorage, or cookies. Maintain all data in volatile JavaScript variables. - Responsiveness: Use CSS Grid/Flexbox to ensure the layout stacks vertically on mobile and uses a side-by-side split screen view on desktop.
- No Popups: Do not use
alert(),prompt(), orconfirm(). Implement modal windows or on-screen toast notifications for user alerts. - Performance: Ensure processing of large text blocks happens on the main thread without blocking UI rendering. Use
requestAnimationFrameif necessary for heavy text manipulation.
