Tiled TMX/TSX and JSON map/tileset loader


cl-tiled is a Common Lisp library for importing TMX/TSX and JSON tilemaps and tilesets generated by Tiled. It aims to fill the same role as other engine-agnostic Tiled importers. Meaning it is not a renderer nor does it provide integration with renderers on its own. Instead it aims to provide an easy, logical way to read map data so it may be imported/rendered in whatever way you wish.


alpha quality. API changes to come. Mostly additions to missing features.

Note that as a current goal, this library aims to be feature complete, not fast nor space efficient.


  • Full TMX/TSX and JSON reading support
  • Support for embedded and external tilesets
  • Support for embededd and external images
  • API support for all layer, tile, object, and terrain types
  • Full support for property objects with distinct data-types (string, number, bool, color, pathname)
  • Orthogonal map support


  • Defining API for isometric, staggred, and hexagonal maps
  • Make the library more efficient
  • Modifying map and writing TMX/TSX and JSON files (if enough demand for this)

Please post any requests/bugs on the issues page.
