Nummern
Canvas spreadsheets with a reproducible Python event log.
Nummern is a macOS spreadsheet app designed around a freeform canvas with multiple independent tables per sheet. Every user action is logged to Python so the document can be recreated by rerunning the generated script.
Nummern is currently in active development. No App Store listing is planned at this time.
Planned capabilities
Freeform spreadsheet canvas
- Multiple independent tables on each sheet.
- Table move/resize on a visual canvas, similar to Numbers-style workflows.
- Adjustable label bands on top, left, bottom, and right.
Script-first reproducibility
- User-visible actions append deterministic Python statements.
- Run the script to rebuild sheets, tables, edits, formulas, and outputs.
- Inspect and edit script directly in an in-app code panel.
Formulas and summaries
- Spreadsheet-style formulas with cell/range references.
- Python formula mode for advanced expressions.
- Summary tables and chart workflows are planned in milestone phases.
Data flows
- CSV import/export and NumPy script export in MVP scope.
- Type-aware columns for number, text, date, time, currency, and percentage.
- Undo/redo and command transactions mapped to script updates.
Development status
Nummern is not a public release yet. Product scope, features, and behavior can still change as implementation milestones progress.
