VS Code Jupyter extension

What it solves

This extension brings the functionality of Jupyter Notebooks directly into Visual Studio Code, allowing developers to create, edit, and run interactive notebooks without leaving their primary code editor. It eliminates the need to switch between a standalone Jupyter interface and a full-featured IDE, combining interactive data science workflows with professional software engineering tools.

How it works

The extension leverages VS Code's built-in notebook support to provide a UI for interacting with Jupyter kernels. It does not act as a kernel itself; instead, it connects to an existing Python environment (where the Jupyter package is installed) or other language kernels (like Julia, R, or C#) installed on the user's machine. Users can select their desired kernel via a kernel picker and execute code cells in a sequence.

Who it’s for

Data scientists, ML engineers, and researchers who use Jupyter Notebooks for exploration and experimentation, but prefer the advanced editing features of Visual Studio Code (such as IntelliSense, VIM support, and integrated diff tools).

Highlights

  • Multi-language support: Works with Python, Julia, R, and C# kernels.
  • IDE Integration: Access to VS Code features like hot exit, find & replace, code folding, and outline view within notebook cells.
  • Codediffing: Includes a notebook-friendly diff tool for comparing changes in code, output, and metadata.
  • Flexible Deployment: Supports local installation, browser-based use via vscode.dev, and GitHub Codespaces.
  • Export Options: Ability to export notebooks to HTML or PDF for presentations.
