Python (.py) zu Jupyter Notebook (.ipynb) online

Need a real .ipynb from a .py file? This py to ipynb converter rebuilds a valid Jupyter notebook so you can open the script in JupyterLab, VS Code, Colab, or Kaggle with proper cells—not a renamed text file. Upload once, keep cell detection on, download. That is convert py to ipynb / convert python to ipynb without installing Jupytext first, and without pasting functions into empty cells by hand after a teammate edited everything in a plain editor.

People search .py to .ipynb, py to ipynb, python to ipynb, or py to ipynb converter when they want notebook structure back. The tool recognizes # %% / VS Code percent markers, # %% [markdown], classic IPython # In[N]: lines (often from jupyter nbconvert --to script), and Spyder cells. No markers? It still splits on top-level def, class, and if __name__ boundaries so you are not stuck with one giant cell. Optional docstring lift and import hoisting keep the opening of the notebook tidy for teaching and reviews.

Comparing py vs ipynb or .py vs .ipynb? Scripts are flat source you run with a normal interpreter; notebooks keep cells, optional outputs, and kernel metadata for interactive work. Round-trip freely: convert ipynb to py on our IPYNB to PY page (keep # %% if you want boundaries), edit the script anywhere, then convert py to ipynb here. That pairing covers both converter directions without guessing which URL to open or renaming extensions and hoping Jupyter forgives you.

What is nbconvert in this story? Jupyter nbconvert usually goes notebook to script. This page is the reverse online path—python to ipynb—when you already have a .py and need cells again. Secure server conversion — processed briefly, not stored afterward. The converter does not execute code; run cells later in a trusted kernel. Not for PDF-to-notebook and not for printing a script as PDF (use Python to PDF). If the script came from Spyder or VS Code with percent cells, leave auto-detect on so markdown and code sections land in separate notebook cells instead of one block.

FAQ

Häufige Fragen

Upload your .py to this py to ipynb converter, keep cell detection on (or adjust options), and download the .ipynb. The output is real nbformat JSON, not a renamed script.

Open this page, drop the Python file, and download the notebook. No account is required for the standard conversion path; the file is processed briefly and not stored afterward.

Same flow as convert python to ipynb / python to ipynb: the converter parses markers or smart-splits the script, then writes ordered notebook cells you can run in Jupyter or Colab.

.py is flat Python source. .ipynb stores cells, metadata, and optional outputs for interactive work. Use this page when you need notebook format; use IPYNB to PY when you need a script again.

jupyter nbconvert often exports notebooks to scripts (# In[N]: style). This tool is the reverse: take that .py (or any percent-format script) and rebuild an .ipynb without a local Jupyter install.

Yes. Export with IPYNB to PY (optional # %% markers), edit the script anywhere, then convert py to ipynb here. Cell boundaries and markdown blocks are preserved when markers are present.

No. It only builds notebook cells from the text. Execute later inside Jupyter, VS Code, Colab, or another trusted kernel.

No. A real notebook needs nbformat structure (cells, metadata). This py to ipynb converter creates that structure; a rename will not open correctly in Jupyter.

It is focused on script → notebook (py to ipynb / .py to .ipynb). For notebook → script use IPYNB to PY. PDF to IPYNB is not supported.

No. Conversion uses secure server processing: the file is handled briefly and not stored afterward.

VS Code / Jupytext # %% cells, # %% [markdown], IPython # In[N]: script exports, and common Spyder separators. Without markers, top-level def/class/__main__ splits still apply.

Yes when that option is enabled. The leading docstring lifts into markdown so the notebook opens with a readable intro instead of a quoted string in code.
