# TileJSON

When loading a vector tiled dataset, Studio will load the associated TileJSON if it is available.

Studio checks for the presence of a Tile JSON file and if present, loads it and extracts metadata. For details, see [Mapbox Tile JSON](https://docs.mapbox.com/help/glossary/tilejson/).

TileJSON files contains metadata about data properties (columns), including names, types and ranges, enabling improved analytics and visualization features.
