Notebook files are JSON files that are saved with the .ipynb extension. They contain both the actual static text written in the file along with outputs and information regarding each session. Notebook files may be exported as static files in the format of LaTeX, PDF, HTML, and more.

Jupyter Notebook File Format

Jupyter Notebooks are hosted on a web server. By default, they are locally hosted. However, external servers may be set up as well. To open an .ipynb file in your browser from the command line, enter the following command:
```console
jupyter notebook <filename>
```
If an extension is not included in the filename, .ipynb is assumed.
