IPYNB to Python Converter

How to convert IPYNB to Python

1. Drop your IPYNB file on the box above, or paste its content into the text box.
2. Check the settings below the box; the defaults suit most files.
3. Press Convert. You see a preview or a summary of the result.
4. Download the .py file, or copy the text.

What is kept when you convert IPYNB to Python

• Code cells are written in order, each marked with a # %% line that VS Code, PyCharm and Spyder recognise as a runnable cell.
• Markdown cells become comments (or are left out, if you choose).
• IPython magics (%matplotlib, %%time) and shell lines (!pip install) are commented out, because they are not valid Python outside Jupyter. Outputs are not included.

Example

For a notebook with a Markdown cell and a code cell that starts with %matplotlib inline, the script is:

Output

# Exported from a Jupyter notebook by EasyCalculatorSmart.
# Markdown cells are comments; IPython magics (%) and shell commands (!) are commented out.

# %% [markdown]
# # Growth
# Rate $g = b/a - 1$.

# %% In[1]
# %matplotlib inline
print(150 / 120 - 1)

About IPYNB and Python files

An .ipynb file is a Jupyter notebook: a JSON document holding Markdown cells, code cells and the outputs (text, tables, charts) saved the last time the cells were run. It opens in Jupyter, JupyterLab, VS Code, Google Colab.

A .py file is a Python script: plain code that runs from top to bottom, without the cells and saved outputs a notebook has. It opens in any Python interpreter, VS Code, PyCharm, Spyder.

Good to know

• Outputs are only as fresh as the last run. Run all cells and save the notebook in Jupyter before converting if you need current results.
• Run the script once from a terminal before relying on it: notebooks often depend on cells being run in a different order.

Privacy and limits

The file is read and converted by this page in your browser; there is no upload and no account. Notebook code is never executed — only the saved cells and outputs are converted. Files up to 25 MB are accepted; a file of the wrong type or a damaged file is rejected with the reason.
