HTML to JSX is a free online converter on AltFTool that converts HTML into JSX: class becomes className, inline styles become objects, attributes are camelCased and void tags are self-closed — no signup and nothing to install.
The conversion runs entirely in your browser: the HTML you paste is converted on your own device and is never uploaded to AltFTool. HTML to JSX is powered by the node-html-parser library, and the JSX result can be copied or downloaded as html-to-jsx.jsx.
The input is HTML markup, either a fragment or a full document.
| Input format | HTML |
|---|---|
| Output format | JSX |
| Output file | html-to-jsx.jsx (text/plain) |
| Runs | In your browser — the input is not uploaded. |
| Library | node-html-parser |
| Category | HTML converters on AltFTool |
Open HTML to JSX on AltFTool — the converter loads straight away, with no account.
Paste your HTML into the left-hand input pane, or press Sample to load a working example.
The conversion runs automatically about 300ms after you stop typing — there is no Convert button, and nothing is uploaded while it works.
If this converter exposes options, open Settings to change them — the output re-runs as you adjust.
Copy the JSX output with the Copy button, or download it as html-to-jsx.jsx.
No. HTML to JSX runs entirely in your browser using the node-html-parser library, so the HTML you paste is converted on your own device and never reaches AltFTool's server.
The node-html-parser library, running in your browser. The JSX you see is that library's output rather than an approximation written here.
There is no server-side limit, because nothing is uploaded — HTML to JSX converts in your browser, so the practical ceiling is your own device's memory.
The result is JSX. Copy it from the output pane in one click, or download it as html-to-jsx.jsx — AltFTool names the file after the converter and serves it as text/plain.
