How to open a .jsx file
Quick, free ways to open JSX on any system.
A .jsx file is a JavaScript React Source File. If double-clicking does nothing, your computer simply does not have an app that reads JSX yet. Here is how to fix that on each operating system, using free software wherever possible.
Open a .jsx file step by step
- Confirm the file really is a .jsx. Drop it into the WhatFileType file identifier, which reads its signature without uploading anything.
- On Windows, open it with VS Code or WebStorm.
- On Mac, use VS Code or WebStorm.
- On Linux, try VS Code or vim.
- Still stuck? Convert the .jsx to js, which opens more widely.

Frequently asked questions
Why can't I open my .jsx file?
Almost always because no installed app understands JSX. Install one of the apps above, or convert the file to a format your existing software already reads.
What is the difference between .js and .jsx?
A .jsx file contains JSX markup for React components. Many projects put JSX in plain .js files too; the .jsx extension just signals that a file has JSX.
Why won't my .jsx file run directly in the browser?
Browsers do not understand JSX. A build tool like Babel or Vite compiles it to plain JavaScript first.
