.TMX File Extension

File created in the Translation Memory Exchange (TMX) format, an open XML standard used for exchanging translation memory (TM) data created by Computer Aided Translation (CAT) and localization applications; may save words or phrases that have been translated from one language to another; used for transferring the translation memory between different tools and vendors.

NOTE: The TMX format was developed by the Localization Industry Standards Association (LISA), who then released the standard under the Creative Commons license.

A TMX file is a video game level map created by Tiled, a 2D level editor. It contains XML-formatted text that describes a map. TMX files can be exported from Tiled for use in developing 2D video games.

Tiled is a free, open-source level editor used to create maps for 2D video games. It allows game developers to place tiles and layers upon a map and add custom properties to those elements. Developers can then export and include the map in a video game.

Maps created in Tiled are saved as TMX files. These files are XML files that include a number of elements that define a map, including the map's tiles, layers, and custom properties. For example, the <map> element is used to define a map's metadata, the <tileset> element is used to define a tileset included in the map, and the <layer> element is used to define a layer included in the map.

How do I export a TMX file from Tiled?

After you finish editing a Tiled map, you can export the map for use in a 2D video game. Tiled allows developers to export maps in a variety of formats, including .JSON, .LUA, .CSV, and Defold's TILEMAP and COLLECTION formats, among others.

To export a map, open the map in Tiled and then select File → Export from the program's menu.

You can open TMX files in Tiled (cross-platform). To do so, you must open the Tiled project that contains your TMX file. Then, select File → Open File in Project from Tiled's menu bar, and open your TMX file.

If you want to review the XML text a TMX file contains outside Tiled, you can do so by opening the file in any text or source code editor.
