How to use JSX Editor

Open and edit JSX files online. Search text and download your .jsx source without installing an editor or uploading files.

1. Import a local .jsx file or paste your JSX source.
2. Edit the text and use Find to locate the section you need.
3. Copy the result or download the updated source file.

export default function Hello() {
  return <h1>Hello, LocalKit!</h1>;
}

export default function Hello() {
  return <h1>Hello, LocalKit!</h1>;

The downloaded source retains your edits. Syntax coloring does not execute, compile or validate the program.
