What is the HTML to JSX?
The HTML to JSX Converter is a free, offline tool that migrates existing HTML into React-ready JSX in one second: class becomes className, for becomes htmlFor, inline styles become style objects, void elements get self-closed, and HTML comments become JSX comments.
Why use HTML to JSX offline?
Migrating a Bootstrap template or designer export to React by hand means hours of tedious renaming and rewriting. Paste the HTML here and get valid JSX instantly — proprietary markup never leaves your browser.
When should you use this tool?
Use it for template migration, designer handoff HTML mockups, bringing legacy email HTML into React, or learning exactly how HTML maps to JSX syntax.
Key Benefits
- Fully sandboxed conversion prevents exposure of proprietary configuration models.
- Fills standard schema attributes automatically.
- Supports dot notation flattening for CSV/Excel exports.
Common Use Cases
- Translating server JSON configurations to YAML for Kubernetes deployment configs.
- Exporting nested JSON API lists to CSV for spreadsheet operations.
- Converting legacy XML schema logs to readable JSON trees.
Developer Notes & Best Practices
class is a reserved word in JavaScript, hence className/htmlFor. Inline scripts and event attributes (onclick) are removed — re-attach behavior with React event props. Full documents convert faithfully but usually need restructuring (head management belongs in react-helmet or Next.js metadata).
- Clean syntax before conversion to ensure elements map correctly.
- Confirm root tag configurations when generating XML files.
- Verify delimiter settings (commas vs semicolons) when converting to CSV.
Common Mistakes
- Forgetting that comments become {/* */} — raw HTML comments are invalid in JSX.
- Expecting <script> tags to survive — they are removed by design.
Limitations
Inline <script> tags and event attributes don't translate to the React model and are removed.
Structured Input/Output Example
<div class="alert"><label for="email">Email</label><input type="email">
<div className="alert"> <label htmlFor="email">Email</label> <input type="email" /> </div>
