Python Data Viewer
Preview Notebooks & NumPy
Only for Mac
$1.99
Mac
Jupyter notebooks and NumPy arrays in Finder. Show the plots the file already contains.
A Mac full of .ipynb and .npy files, and macOS can't preview a single one.
Python Data Viewer fixes that: notebooks render as documents: markdown, code, and the cached outputs already in the file, plots included and arrays open as a data grid.
- Finder thumbnails that show your notebook's actual figures; matrices as heatmaps
- Quick Look for .ipynb, .npy, and .npz... juist press Space!
- Notebooks: markdown, In[n] code cells, results, tracebacks, images
- Export notebooks as runnable .py scripts or Markdown (images included)
- Arrays: sortable grid, heatmap view, chart builder
- CSV export
