What Code Syntax Highlighter does
Highlight source code using a selected or detected language and export a readable presentation for review or documentation.
Worked example
Input
const total = prices.reduce((a, b) => a + b, 0);
Result
JavaScript tokens highlighted by role
How it works
A syntax grammar classifies tokens such as keywords, strings, numbers and comments, then assigns visual styles. It does not compile or execute the code.
Developer workflows
- Create readable documentation snippets
- Inspect unfamiliar code structure
- Prepare code examples for presentations or notes
Security and compatibility checks
- Language detection can be wrong for short or ambiguous snippets.
- Highlighting does not validate correctness or safety.
- Check color contrast in the final theme and export.
Frequently asked questions
Does highlighting run the pasted code?
No. It only analyzes text for display.
Why was the language detected incorrectly?
Small snippets often share syntax; choose the language manually for reliable highlighting.
