Converting Jupyter Notebooks to Marimo

IMPORTANT: When asked to translate a notebook, ALWAYS run

uvx marimo convert <notebook.ipynb> -o <notebook.py>

FIRST before reading any files. This saves precious tokens - reading large notebooks can consume 30k+ tokens, while the converted .py file is much smaller and easier to work with.

Steps

Convert using the CLI

Run the marimo convert command via

uvx

so no install is needed:

bash

uvx marimo convert <notebook.ipynb> -o <notebook.py>

This generates a marimo-compatible

.py

file from the Jupyter notebook.

Run
marimo check
on the output

bash

uvx marimo check <notebook.py>

Fix any issues that are reported before continuing.

Review and clean up the converted notebook

Read the generated

.py

file and apply the following improvements:

Ensure the script metadata block lists all required packages. The converter may miss some.
Drop leftover Jupyter artifacts like
```
display()
```
calls, or
```
%magic
```
commands that don't apply in marimo.
Make sure the final expression of each cell is the value to render. Indented or conditional expressions won't display.
If the original notebook requires environment variables via an input, consider adding the
```
EnvConfig
```
widget from wigglystuff. Details can be found here.
If the original notebook uses ipywidgets, replace them with corresponding ui from marimo. A slider, for example, would be replaced with
```
mo.ui.slider()
```
.

Run
marimo check
again after your edits to confirm nothing was broken.
