Conversion Example

Before Conversion (.ipynb code cell)

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 10, 100)
y = np.sin(x)
plt.plot(x, y)

After Conversion (.py) - All Options Enabled

#!/usr/bin/env python3
# coding: utf-8
# Converted from: example.ipynb
# Generated at  : 2025/01/15 10:30:00

# In[1]:
# %matplotlib inline
import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 10, 100)
y = np.sin(x)
plt.plot(x, y)

Frequently Asked Questions

Q. What conversion is performed?

Code cells from Jupyter Notebook are output as-is, while markdown cells are output as comments in the Python script.

Q. What happens to markdown cells?

Markdown cells are output as comments in the .py file.

Q. Is it secure?

All processing is done in your browser, and files are never sent to external servers. You can use it with confidence.

Troubleshooting

Cannot load file

Verify that the file is in .ipynb format
Check that the file is not corrupted (open it in a text editor to confirm it's valid JSON)
