Detailed Overview & How It Works
The HTML Viewer helps developers format JSON structures, escape HTML entities, and preview code in sandboxed contexts. The client-side tools execute locally, providing fast formatting and validation.
Sandboxed HTML Rendering
The HTML Viewer renders code inside a sandboxed iframe, separating executed scripts and styles from the main website page to ensure safety.
Raw Code Privacy
Data Security: Development code, API payloads, and config values are kept private. All formatting and rendering happen locally in your browser.
Pro Tips & Best Practices for Developer Tools
- Validate Bracket Matching: Ensure JSON files have matching brackets before formatting to identify parsing errors.
- Escape Special Characters: Convert special characters to HTML entities to prevent rendering and script injection bugs.
- Preview Code in Full Page: Maximize the preview viewport using the expand button to review page layouts easily.
- Use the Escape Key: Press the Escape (Esc) key to quickly close the full-page HTML preview and return to split view.
