Whitespace Visualizer

Summary

Paste any text and instantly see all invisible whitespace characters rendered as distinct symbols.

How it works

1. Paste or type your text into the input area on the left.
2. Choose which character types to highlight: spaces, tabs, newlines, and other control characters.
3. The visualizer replaces each invisible character with a distinct symbol.
4. Color-coded highlights make each character type easy to identify at a glance.
5. Copy the plain text or the annotated output using the buttons provided.
6. Use the summary panel to count how many of each whitespace type appear in your text.

Use cases

• Debug unexpected whitespace issues in code or configuration files.
• Detect trailing spaces or mixed tabs and spaces in source code.
• Inspect copy-pasted text for hidden characters from external sources.

• Find non-breaking spaces or zero-width characters causing layout bugs.
• Check API responses or log output for unexpected control characters.
• Teach students the difference between whitespace character types.
• Audit document formatting before submission or publication.
