TumblerSpreadsheet compatibility
Check the supported grid, calculation, and editing scope.
Grid and formatting
- Virtualized rows and columns, ordinary merges, frozen panes, and cell formatting.
- Table value sorting and supported filters are view projections. They are not written back to the workbook.
- Supported conditional rules affect font, fill, and borders. Other rule families remain incomplete.
Formula limits
Ordinary formulas use a bounded calculation engine. Unsupported functions and formula structures fall back to producer caches with diagnostics.
- Shared, array, data-table, dynamic-array, and external-workbook formulas are not editable.
- Structural row and column edits are not available.
- Editing rich/shared strings replaces the value with plain inline text.
Charts and qualification
Supported embedded charts render as native overlays. Chart-data authoring, pivots, non-chart drawings, and broader workbook features remain incomplete.
