TSX to HTML Converter

How to convert TSX to HTML

1. Paste your TSX code into the input field — a full component file, a return block, or a JSX snippet with TypeScript types.
2. Click "Convert" — TypeScript declarations are stripped, JSX attributes are renamed, and clean HTML appears in the output panel.
3. Switch to "HTML → TSX" using the toggle above if you need the reverse direction.
4. Click "Copy" to copy the HTML to clipboard, or "Download .html" to save it locally.
5. Use the output in a static HTML page, email template, or any non-React context.

How the TSX to HTML converter works

The converter processes TSX in two stages. First it strips TypeScript-specific syntax: import statements, interface declarations, type alias declarations, and as-type assertions inside JSX expressions. If the input is a full component function, it extracts only the JSX return body using a balanced-parentheses parser. Then it applies the reverse JSX → HTML transformations: className → class, htmlFor → for, camelCase events → lowercase, style objects → CSS strings, and void elements normalized for HTML. The entire conversion runs in your browser — no data is sent to any server.

// Input TSX:
import React from 'react'

interface CardProps {
  title: string
  disabled?: boolean
}

const Card: React.FC<CardProps> = ({ title }: CardProps) => {
  return (
    <div className="card" tabIndex={0}>
      <h2>{title as string}</h2>
      <input type="text" readOnly disabled={false} />
    </div>
  )
}

// Output HTML:
<div class="card" tabindex="0">
  <h2>{title}</h2>
  <input type="text" readonly>
</div>

TypeScript syntax that gets stripped

The converter removes TypeScript-specific constructs that have no HTML equivalent. The stripping is conservative — it targets known patterns and avoids touching the JSX markup itself.

JSX attributes converted back to HTML

After TypeScript stripping, the converter applies the full JSX → HTML reverse transformation. Every JSX attribute is mapped back to its HTML equivalent.

Return body extraction for full components

When the input contains a full React component function, the converter automatically extracts the content of the return statement. It supports two common patterns:

// Pattern 1: arrow function with block body and return
const MyComponent: React.FC = () => {
  return (
    <div className="card">...</div>  // ← extracted
  )
}

// Pattern 2: concise arrow body
const MyComponent = () => (
  <div className="card">...</div>    // ← extracted
)

// Pattern 3: JSX markup only (no component wrapper)
<div className="card">...</div>      // ← used as-is, no extraction needed

The extraction uses a balanced-parentheses parser that correctly handles deeply nested JSX with embedded JavaScript expressions. It does not use regex for parenthesis matching, which means it handles complex real-world components without mismatching open and close parens.

Limitations: what TSX to HTML cannot convert

TSX is a superset of HTML. The TypeScript layer can be stripped mechanically, but the JSX layer still contains JavaScript expressions that have no static HTML equivalent:

• JavaScript expressions — {variable}, {condition ? a : b}, {items.map(...)} are left as-is in the output. Replace them with the actual rendered values.
• Component references — <Button />, <UserCard user={user} />, and other component tags are not HTML elements. The converter cannot know what HTML they render.
• Conditional rendering — {isVisible && <Panel />} expressions are left in the output. Resolve the condition by hand.
• React-specific props — key, ref, and dangerouslySetInnerHTML are left as attributes. Remove them manually after conversion.
• Deep TypeScript generics — if stripping fails for unusually nested types, paste only the JSX return body as input.
