What is a TSX file?
A .TSX file is most often a React TypeScript File developed by Microsoft. Developers use these files to write React user interface components with TypeScript. The .TSX extension allows developers to embed HTML-like syntax directly inside the TypeScript code.
In rare cases, a .TSX file can be a Tiled Tileset file used by the Tiled Map Editor. Game developers use this XML-based format to store map tile designs.
How to open TSX files?
You can open a React TypeScript File using any plain text editor or integrated development environment (IDE). Popular choices include Visual Studio Code, WebStorm, and Notepad++. To open a Tiled Tileset, you need the Tiled Map Editor software.
Because .TSX has multiple possible meanings, we recommend using viewer.online/tsx to identify the actual format of your file. Our tool can analyze .TSX files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Software and tools
If you need to compile a .TSX file into executable JavaScript, you must use the TypeScript Compiler (tsc) or build tools like Vite or Webpack. For game tilesets, Tiled Map Editor is the standard tool.
Best practices and troubleshooting
If you encounter syntax errors when opening a .TSX file, make sure your editor supports TypeScript and JSX syntax. If you need to convert your file to standard JavaScript or plain text, we recommend using convert.guru. You can convert .TSX files to .JS, .JSX, or .TXT target formats easily.
Summary
viewer.online/tsx is useful for identifying, inspecting, and understanding .TSX files without installing software or dealing with compatibility problems. Whether your file contains React components or game map data, our online viewer provides a fast and safe way to inspect its contents.
