About This Tool

The Code Viewer Tool renders and highlights code snippets across multiple languages for documentation, reviews, education, and knowledge bases. It targets developers, technical writers, educators, and QA engineers who embed code blocks into pages or docs and require consistent rendering across languages.

Inputs are the raw code text and an optional language hint; the tool tokenizes, applies language rules, and outputs an HTML fragment with preserved formatting and safe escaping.

Users benefit from fast rendering, consistent syntax colors, and easy embedding in pages, guides, or knowledge bases without installing local tooling.

Unique differentiators include broad language coverage, safe HTML output, and the ability to auto-detect language with deterministic results.

Frequently Asked Questions

Find Quick Answers

What languages are supported?

The tool supports JavaScript, Python, Java, C/C++, HTML, CSS, JSON, YAML, and others via language grammars; auto-detect attempts to identify the language when not provided.

Can I embed the output HTML in static pages?

Yes. The tool emits a self-contained HTML fragment with sanitized code, suitable for embedding directly into static or dynamic pages without further processing.

Does the tool execute code or run it?

No. The tool only renders and highlights code for display; it does not execute or evaluate code snippets.

How is safety handled?

Input is escaped to prevent HTML/script injection; the output is a static representation that cannot run code.
