CellSharp is maintained in the author's free time. The roadmap expresses general direction rather than deadlines or guaranteed features.
CellSharp 1.0 establishes the typed read, write, schema, validation, template, worksheet-layout, and multi-sheet APIs as the stable core. The 1.x line prioritizes compatibility, bug fixes, documentation, interoperability, and improvements justified by real-world usage.
Stable does not mean feature-complete for every Excel capability. New features may be added compatibly when their API and maintenance cost fit the library's focused scope.
- Remove friction found through real usage and improve diagnostics and examples.
- Broaden Excel and LibreOffice interoperability when concrete compatibility issues emerge.
- Improve realistic-workbook performance and resource usage where measurements justify it.
- Add small, backwards-compatible features with clear practical value.
- Charts.
- Shapes, sparklines, richer drawings, and pivot-oriented features.
