# Export a model to JSON

The trained CatBoost model can be saved as a JSON file. This file can be accessed later to apply the model. Refer to the [CatBoost JSON model tutorial](https://github.com/catboost/tutorials/blob/master/model_analysis/model_export_as_json_tutorial.ipynb) for format details.
