# Create and edit Jupyter notebooks

> **Warning:**
> The following is only valid when the Python and Jupyter plugins are [installed and enabled](managing-plugins.html)!

Procedure: Set up your project

1. In IntelliJ IDEA, create a new [Python project](creating-empty-python-project.html)  .

2. [Install](https://www.jetbrains.com.cn/en-us/help/pycharm/installing-uninstalling-and-upgrading-packages.html)  the jupyter package for the selected interpreter.

3. When all the project analysis processes are finished, you are ready to start working with the notebook files.

## Create and open Jupyter notebooks

To open an existing `.ipynb` file, follow the  same steps as for the files of the other types. If needed, you can create a notebook file.

Procedure: Create a notebook file

1. Do one of the following:

* Right-click the target directory in the Project tool window and select New from the context menu.

* Press `Alt+Insert` (Windows), `⌘ N` (macOS), `⌃ N` (IntelliJ IDEA Classic (macOS)), `⌘ N` (macOS System Shortcuts), `Alt+Insert` (XWin), `Alt+Insert` (GNOME), `Alt+Insert` (KDE), `Alt+Insert` (Emacs), `Alt+Insert` (Sublime Text), `⌘ N` (Sublime Text (macOS)), `Alt+Insert` (NetBeans), `Alt+Insert` (Visual Studio), `⌘ ⌃ N` (Visual Studio (macOS)), `Alt+Insert` (Eclipse), `⌘ N` (Eclipse (macOS))

2. Select Jupyter Notebook .

3. In the dialog that opens, type a filename.

A notebook file has the `*.ipynb` extension and is marked with the corresponding icon ![Jupyter](https://resources.jetbrains.com.cn/help/img/idea/2026.2/python-jupyter.icons.org.jetbrains.plugins.notebooks.jupyter.expui.jupyterNotebook.svg).

Procedure: Convert a Python file to a Jupyter notebook

1. Right-click the file in the `Project` tool window.

2. Select `Convert to Jupyter Notebook` from the context menu.

Procedure: Convert a Jupyter notebook to a Python file

1. Right-click the file in the `Project` tool window.

2. Select `Convert to Python File` from the context menu.

Procedure: Export Jupyter notebooks

You can export Jupyter notebooks to various formats:

1. Right-click the Jupyter notebook file in the Project tool window.

2. Select `Export Notebook As` and then select the format from the list.

## Edit Jupyter notebooks

You can apply various editing actions to one cell or to the entire notebook. Press the `Ctrl+A` (Windows), `⌘ A` (macOS), `⌘ A` (IntelliJ IDEA Classic (macOS)), `⌘ A` (macOS System Shortcuts), `Ctrl+A` (XWin), `Ctrl+A` (GNOME), `Ctrl+A` (KDE), `Ctrl+X, H` (Emacs), `Ctrl+A` (Sublime Text), `⌘ A` (Sublime Text (macOS)), `Ctrl+A` (NetBeans), `Ctrl+A` (Visual Studio), `⌘ A` (Visual Studio (macOS)), `Ctrl+A` (Eclipse), `⌘ A` (Eclipse (macOS)) once to select a cell at the caret and press `Ctrl+A` (Windows), `⌘ A` (macOS), `⌘ A` (IntelliJ IDEA Classic (macOS)), `⌘ A` (macOS System Shortcuts), `Ctrl+A` (XWin), `Ctrl+A` (GNOME), `Ctrl+A` (KDE), `Ctrl+X, H` (Emacs), `Ctrl+A` (Sublime Text), `⌘ A` (Sublime Text (macOS)), `Ctrl+A` (NetBeans), `Ctrl+A` (Visual Studio), `⌘ A` (Visual Studio (macOS)), `Ctrl+A` (Eclipse), `⌘ A` (Eclipse (macOS)) twice to select all cells in the notebook.

> **Note:**
> IntelliJ IDEA updates the source code and the preview of the notebook if it has been changed externally.

The editor for Jupyter notebooks has two modes: the edit mode and the command mode. Depending on the mode, you can either edit code in notebook cells or use keyboard shortcuts to perform specific actions with cells.

Procedure: Edit mode

Packages:

![Package completion](https://resources.jetbrains.com.cn/help/img/idea/2026.2/py_ds_complete_package.png)

DataFrame columns:

> **Note:**
> The auto-completion of DataFrame columns names is available in runtime. IntelliJ IDEA will suggest the names for columns only if the cell where the DataFrame is created has already run in the current kernel session.

* Intention actions and quick fixes. You can [add the missing
imports](creating-and-optimizing-imports.html) by using the intention actions.

![Quick-fix for the missing import](https://resources.jetbrains.com.cn/help/img/idea/2026.2/py_ds_quick_fix_import.png)

Note that you can add an import statement to the current cell or to the first cell of the notebook.
