Does this send my JSX anywhere?

No. Conversion runs entirely in your browser using a hand-written JSX tokenizer, not a Babel/JSX parser.

Is this a real JSX parser?

No. It's a hand-written tokenizer/regex-based parser for simple, well-formed JSX markup, not a full JSX/Babel AST parser. It's built with no DOM globals at module scope so it runs anywhere.

What happens to expressions like {someVariable}?

Expression containers that aren't a style object or a quoted string literal (e.g. {someVariable} or {condition && }) pass through as literal text, since this tool doesn't evaluate JSX; it isn't a real JSX runtime.

How is style={{ ... }} handled?

A style object like style={{ color: "red", fontSize: "12px" }} is converted back to an inline style string: style="color: red; font-size: 12px".

JSX to HTML Converter - Convert JSX to HTML Online

Overview

Introduction

Sometimes you need the plain HTML a JSX snippet renders to, whether for an email template, a static export, or documentation, without spinning up a React build.

This tool converts simple JSX markup back into plain HTML entirely in your browser.

What Is JSX to HTML Converter?

The inverse of the HTML to JSX Converter: a hand-written tokenizer that rewrites className to class, htmlFor to for, camelCase attributes back to kebab-case, and style objects back to inline style strings.

It shares its attribute-name table with the HTML to JSX Converter, so the two tools stay consistent with each other.

How JSX to HTML Converter Works

JSX block comments are converted to HTML comments first, then each tag's attributes are rewritten individually: a style={{ ... }} object is parsed into CSS declarations, quoted string attributes are unwrapped, and other attribute names are converted through the shared reverse name table or a generic camelCase-to-kebab-case fallback.

Expression container attributes and children that aren't a style object or a quoted string (e.g. a variable or a conditional) are passed through as literal text rather than evaluated, since there's no JSX runtime involved.

When To Use JSX to HTML Converter

Use it to get the plain HTML a JSX component renders without setting up a build, for pasting into an email template or a static page.

It's also useful for documentation that needs to show the resulting markup rather than the JSX source.

Often used alongside HTML to JSX Converter, HTML Formatter and HTML Minifier.

Features

Advantages

Runs entirely client-side.
Converts style objects back to a single inline style string, not just a per-property list.
Shares its attribute mapping table with the HTML to JSX Converter, so a round trip through both tools stays predictable.

Limitations

This is not a real JSX/Babel parser; it's a hand-written tokenizer for simple, well-formed JSX and doesn't build an AST or evaluate anything.
Expression containers holding a variable, function call, or conditional (anything other than a style object or quoted string) pass through as literal text rather than being evaluated to their rendered value.

Examples

className, a style object, and a self-closing tag

Input

<div className="card" style={{ color: "red", fontSize: "12px" }}>
  <img src="a.png" />
</div>

Output

<div class="card" style="color: red; font-size: 12px">
  <img src="a.png" />
</div>

className becomes class, the style object collapses to an inline style string, and the self-closing <img /> is left as-is (valid in HTML5 too).

Best Practices & Notes

Best Practices

Keep input to markup-level JSX (tags, attributes, style objects, text); this tool doesn't evaluate component logic.
Replace any {variable} or {expression} left in the output with its actual rendered value by hand before shipping the HTML.
Run the HTML Formatter afterward for consistent indentation if you're pasting the result into a larger file.

Developer Notes

Built on a regex-based tag/attribute tokenizer with no DOM API usage, using the reverse of the HTML to JSX Converter's shared attribute-name table plus a generic camelCase-to-kebab-case fallback.

JSX to HTML Converter Use Cases

Getting the plain HTML behind a small JSX snippet for an email template
Documenting the markup a component renders without a build step
Converting a design system component's JSX example into static HTML for a style guide

Common Mistakes

Expecting {someVariable} or conditional expressions to evaluate to their rendered value; this tool passes them through as literal text instead.
Assuming data-* or aria-* props get renamed; they're already valid HTML attribute names and are left untouched.

Tips

For markup with dynamic data, replace expression containers with their real values before converting, so the HTML output is complete.
If a style object doesn't convert cleanly, check for a trailing comma or nested object; this tool expects a flat, single-level style object.
