JSON Map Format

Tiled can export maps as JSON files. To do so, simply select “File > Export As” and select the JSON file type. You can export json from the command line with the --export-map option.

The fields found in the JSON format differ slightly from those in the TMX Map Format, but the meanings should remain the same.

The following fields can be found in a Tiled JSON file:

Changelog

Tiled 1.10

Renamed the class property on Tile (Definition) and Object back to type, to keep compatibility with Tiled 1.8 and earlier. The property remains class in other places since it could not be renamed to type everywhere.

Tiled 1.9

Renamed the type property on Tile (Definition) and Object to class.
Added class property to Map, Tileset, Layer, Wang Set and Wang Color.
Added x, y, width and height properties to Tile (Definition), which store the sub-rectangle of a tile’s image used to represent this tile. By default the entire image is used.
Added tilerendersize and fillmode properties to Tileset, which affect the way tiles are rendered.

Tiled 1.8

Added support for user-defined custom property types. A reference to the type is saved as the new propertytype property of Property.
The Property element can now have an arbitrary JSON object as its value, in case the property value is a class. In this case the type property is set to the new value class.
Added parallaxoriginx and parallaxoriginy properties to Map.
Added repeatx and repeaty properties to Layer (applies only to image layers at the moment).

Tiled 1.7

The Tile (Definition) objects in a tileset are no longer always saved with increasing IDs. They are now saved in the display order, which can be changed in Tiled.

Tiled 1.6

The version property is now written as a string (“1.6”) instead of a number (1.5).

Tiled 1.5

Unified cornercolors and edgecolors properties of Wang Set as the new colors property and added a type field.
Wang Color can now store properties.
Added transformations property to Tileset (see Transformations).
Removed dflip, hflip and vflip properties from Wang Tile (no longer supported).
Added parallaxx and parallaxy properties to the Layer object.

Tiled 1.4

Added objectalignment to the Tileset object.
Added tintcolor to the Layer object.
Added object as possible type of Property.

Tiled 1.3

Added an editorsettings property to top-level Map and Tileset objects, which is used to store editor specific settings that are generally not relevant when loading a map or tileset.
Added support for Zstandard compression for tile layer data ("compression": "zstd" on tile layer objects).
Added the compressionlevel property to the Map object, which stores the compression level to use for compressed tile layer data.

Tiled 1.2

Added nextlayerid to the Map object.
Added id to the Layer object.
The tiles in a Tileset are now stored as an array instead of an object. Previously the tile IDs were stored as string keys of the “tiles” object, now they are stored as id property of each Tile object.
Custom tile properties are now stored within each Tile instead of being included as tileproperties in the Tileset object.
Custom properties are now stored in an array instead of an object where the property names were the keys. Each property is now an object that stores the name, type and value of the property. The separate propertytypes and tilepropertytypes properties have been removed.

Tiled 1.1

Added a chunked data format, currently used for infinite maps.
Templates were added. Templates can be stored as JSON files with an Object Template object.
Tilesets can now contain Terrain Sets. They are saved in the new Wang Set object (since Tiled 1.1.5).
