Private browser-first tabular workflow

v10.78 connects viewing, editing, validation, cleanup, conversion, joining, reshaping and spreadsheet import/export around the established CSV/Excel tools. Text and supported workbook files are handled in browser memory; large files remain limited by device memory and browser rendering cost.

CSV and spreadsheet boundaries

CSV has no universal schema or type system. Delimiter detection and type summaries are practical heuristics, while repairs create a new copy instead of silently altering the source. Excel conversion focuses on cell values and simple worksheets rather than promising perfect preservation of formulas, macros, charts, external links, formatting or every workbook feature.
