📖 How to Use
Paste text to normalize, select the normalization options you want to apply, and click 'Normalize'. The tool processes the text step by step according to selected options, showing changes made.
⚡ How It Works
Uses regex and Unicode character mapping for text normalization. Smart quotes are replaced through character mapping; extra whitespace is cleaned via regex; zero-width characters are detected and removed by Unicode range; line breaks are unified (CRLF→LF, CR→LF).
💼 Use Cases
Clean formatting when copying from web pages; unify text formats from different sources; prepare text data for programming; clean content from PDF/Word; standardize user-input text data.
❓ FAQ
❓ Do I need to upload data?
No. All normalization is done entirely in your browser. Your text is never uploaded to any server.
❓ What normalization features are available?
Smart quotes conversion (''""→'" ), dash unification (various dashes→standard hyphen), extra whitespace cleanup, line break normalization (CRLF→LF), zero-width character removal, punctuation unification.
❓ What are zero-width characters?
Zero-width characters are invisible Unicode characters (e.g., U+200B zero-width space, U+200D zero-width joiner) often introduced when copying from web pages. They can cause text processing issues and are automatically removed.
❓ Why convert smart quotes?
Text copied from web pages, PDFs, or Word often contains curly/smart quotes ('' ""), which can cause problems in programming or certain systems. The tool converts them to straight quotes (' ").
❓ Is this tool free?
Yes, completely free. No registration or payment required.
❓ Can I copy the result?
Yes. Normalized text supports one-click copy to clipboard or download as .txt file.
