- Mac users who read or maintain Jupyter notebooks
- Worth noticing
- The page says saves use standard nbformat 4 and preserve untouched cells byte-for-byte.
Field notes
The page describes search across both notebook sources and printed outputs, with case, whole-word, and regular-expression options; replace applies to cell sources. It says edits are undoable and that untouched cells in a saved standard nbformat 4 file remain byte-stable. Export options include self-contained HTML, paginated PDF, Markdown with accompanying images, and scripts containing code cells.
