Exporting¶

Export marimo notebooks to other file formats at the command line using

marimo export

Export to static HTML¶

Export the current view your notebook to static HTML via the notebook menu:

You can also export to HTML at the command-line:

marimo export html notebook.py -o notebook.html

or watch the notebook for changes and automatically export to HTML:

marimo export html notebook.py -o notebook.html --watch

Export to a Python script¶

Export to a flat Python script in topological order, so the cells adhere to their dependency graph.

marimo export script notebook.py -o notebook.script.py

Top-level await not supported

Exporting to a flat Python script does not support top-level await. If you have top-level await in your notebook, you can still execute the notebook as a script with python notebook.py.

Export to markdown¶

Export to markdown notebook in top to bottom order, so the cells are in the order as they appear in the notebook.

marimo export md notebook.py -o notebook.md

This can be useful to plug into other tools that read markdown, such as Quarto or MyST.

You can also convert the markdown back to a marimo notebook:

marimo convert notebook.md > notebook.py

Export to Jupyter notebook¶

Export to Jupyter notebook in topological order, so the cells adhere to their dependency graph.

marimo export ipynb notebook.py -o notebook.ipynb

🏝️ Embed marimo outputs in HTML using Islands¶

Preview

Islands are an early feature. While the API likely won’t change, there are some improvements we’d like to make before we consider them stable. Please let us know on GitHub if you run into any issues or have any feedback!

marimo islands are a way to embed marimo outputs and/or python code in your HTML that will become interactive when the page is loaded. This is useful for creating interactive blog posts, tutorials, and educational materials, all powered by marimo’s reactive runtime.

Check out an example island-powered document.

Islands in action¶

Advanced topic!

Islands are an advanced concept that is meant to be a building block for creating integrations with existing tools such as static site generators or documentation tools.

In order to use marimo islands, you need to import the necessary JS/CSS headers in your HTML file, and use our custom HTML tags to define the islands.

    </marimo-cell-output>
    <marimo-cell-code hidden>mo.md('Hello islands 🏝️!')</marimo-cell-code>
  </marimo-island>

Generating islands¶

While you can generate the HTML code for islands yourself, it it recommend to use our MarimoIslandGenerator class to generate the HTML code for you.

class marimo.MarimoIslandGenerator(app_id: str = 'main')¶

Generates Marimo islands for embedding in other pages.

This is a great way to use another SSG framework that converts Python code to HTML using marimo-islands.

Generally you will want to:

Find all the code snippets and add them to the generator.
Build the app.
Replace all code snippets with the rendered HTML.
Include the header in the

tag.

Example¶

from marimo import MarimoIslandGenerator

generator = MarimoIslandGenerator()
block1 = generator.add_code("import marimo as mo")
block2 = generator.add_code("mo.md('Hello, islands!')")

# Build the app
app = await generator.build()

# Render the app
output = f"""
<html>
    <head>
        {generator.render_head()}
    </head>
    <body>
        {block1.render(display_output=False)}
        {block2.render()}
    </body>
</html>
"""

Public methods

`from_file`(filename[, display_code])	Create a MarimoIslandGenerator and populate MarimoIslandStubs using code cells from a marimo *.py file.
`add_code`(code[, display_code, ...])	Add a code cell to the app.
`build`()	Build the app.
`render_head`(*[, version_override, ...])	Render the header for the app.

static from_file(filename: str, display_code: bool = False) → MarimoIslandGenerator¶
