HTML → JSX Converter

Convert HTML markup into the attribute names and style format used in React JSX.

Category: Converters

When to use?

Use it to convert HTML from a designer or external source into JSX syntax before pasting into a React component. It auto-handles class → className, for → htmlFor, and more.

How to use

  • Enter HTML code.
  • See the JSX-converted result.
  • Copy the JSX for your React component.

Input Explanation

Enter pure HTML markup to paste into React, Next.js, etc.

Calculation Basis

It parses the HTML and globally replaces attribute names to camelCase per JSX rules: class → className, for → htmlFor, inline style="color:red" → style={{color:"red"}}.

Usage Examples

  • Apply HTML samples to React - Convert HTML attributes like class, for, and style into JSX syntax.
  • Tidy design mockup code - Clean a copied HTML fragment before adding it to a React component.
  • Migrate legacy markup - Convert old HTML to JSX when moving it into a React project.

Examples

  • <div class="container" for="input"> → <div className="container" htmlFor="input">
  • HTML with onclick → JSX with the camelCase onClick attribute

Cautions

  • Malformed source data can cause parsing errors or broken output.
  • A mismatched encoding standard or complex nested data may break or drop the structure.

Guides

HTML vs. JSX attributes

JSX needs React-style attribute names: class becomes className, for becomes htmlFor, and so on.

Verify after auto-conversion

Check complex event attributes, inline styles, and SVG attributes manually even after auto-conversion.

FAQ

How is the class attribute converted?

It becomes className, used in React JSX.

Does it handle inline style?

Yes, it converts the style string into JSX object notation.

Are comments converted?

HTML comments must be changed to the brace comment form JSX uses.

What about self-closing tags?

JSX requires all tags closed, so tags like br and img convert to self-closing form.
