ipynb-quicklook for Mac

What this tool does

ipynb-quicklook is a Quick Look extension for macOS that gives instant previews of Jupyter/IPython notebook files (.ipynb) directly inside Finder. Instead of launching Jupyter or another editor, you can glance at the notebook’s contents — cells, text, and outputs — from the file browser.

Key benefits

• Fast access to notebook content without opening a separate application, speeding up routine checks.
• Improved organization when working with many notebooks, making it simpler to locate the right file.
• Better productivity for iterative review of results and documentation embedded in notebooks.
• Seamless integration with macOS, so the preview behaves like other Quick Look previews.

Who will find it useful

• Data scientists and analysts who regularly inspect multiple notebooks.
• Researchers who need to quickly review experiment notes or results.
• Developers and educators sharing notebooks and wanting a lightweight way to scan files.

How to use it

Install the plugin according to the project’s instructions, restart Finder if required, then select any .ipynb file and press Space (Quick Look shortcut) to see a live preview. No full notebook server or editor is necessary for most read-only checks.

Free alternative and quick reference

• CheatSheet (free): a lightweight plugin that also enables Finder previews for .ipynb files and integrates cleanly with macOS.
• Instant preview capability that mirrors core Quick Look behavior, making it convenient to scan notebooks.
• Useful for users who prefer an open-cost option that still reduces the need to open notebooks in an editor.

Summary

This Quick Look plugin simplifies interaction with Jupyter notebooks on macOS by letting you preview .ipynb files directly in Finder. It’s a practical convenience for anyone who manages many notebooks and wants quicker, less disruptive access to their contents.
