HTML Formatter — Pretty Print HTML Workspace
generic-text workspace — use xml-formatter patterns and html-encoder-decoder for HTML workflows
How to Use This Tool
- Paste HTML source into generic-text textarea.
- Click Transform — passthrough for html-formatter slug today.
- Manually indent or use IDE HTML format command.
- Use html-encoder-decoder when inserting HTML into attributes.
- Use xml-formatter when document is XHTML-like strict markup.
- Copy workspace output for tickets after manual formatting.
About This Tool
Email templates, legacy JSP fragments, and scraped markup often arrive as one-line HTML that is painful to review in tickets. VSPIC html-formatter maps to generic-text client kind in missing-tools-handlers.generated.ts — textarea and Transform with slug-aware transformText.
The slug html-formatter does not match beautify or format rules in transformText today — Transform returns input unchanged. Browser-native HTML pretty printing needs a dedicated parser pipeline not wired to this slug yet. Use xml-formatter proxy patterns for strict markup trees when content is XML-like, html-encoder-decoder for entity encoding before embedding, and editor format document commands for full HTML5 beautify.
Common use cases
- •Inspect HTTP headers and user-agent strings
- •Analyze email headers for phishing investigation
- •Generate strong passwords for staging environments
Why use VSPIC for ?
- Honest generic-text passthrough documentation.
- Local paste workspace for HTML review drafts.
- Points to html-encoder-decoder for encoding workflows.
- Client-side — unreleased templates stay on device.
- Copy button for attachment workflows.
- Free staging before CMS commit.
HTML formatting expectations
Production HTML formatters parse with HTML5-aware rules, respect void elements, and indent nested tags consistently. Template engines often ship their own beautify plugins.
Our slug documents generic-text passthrough until dedicated HTML parser formatting ships.
generic-text passthrough for html-formatter
html-formatter lacks transformText substring matches. Output equals input on Transform.
Use html-encoder-decoder for embedding
Formatting does not escape < for JavaScript or attribute contexts. html-encoder-decoder encodes entities when inserting markup into templates safely.
Use xml-formatter for strict markup
XHTML and XML-like templates with strict tag rules can use xml-formatter proxy widget when DOMParser XML mode accepts the document.
IDE and CLI alternatives
Prettier, js-beautify, and VS Code Format Document handle HTML5 recovery semantics. Use those for repository commits; this page for quick paste staging.
Email HTML caveats
Email clients ignore many CSS rules — formatting source does not fix rendering. Inline styles remain manual.
Security when handling untrusted HTML
Pasted HTML may contain script tags. Do not innerHTML untrusted paste into live pages. Sanitize in application pipelines.
Relationship to markdown-preview
markdown-preview renders Markdown to HTML — different source language. Use markdown-preview for MD authoring, not HTML source indent.
Future dedicated HTML beautify handler
Registry may add client HTML formatter kind with DOM-based indent. Content will update when handler ships.
