Could you build this?
Partial A basic CSV reader UI can be vibe-coded, but a high-performance native spreadsheet supporting XLSX and responsive rendering requires custom desktop systems engineering.
What it would actually take: A real version requires a native Swift/AppKit codebase with a custom virtualized rendering layer (Core Graphics or Metal) and a memory-efficient XLSX parser. The hard parts are building a responsive grid that can handle millions of cells without UI hitching and implementing an AST-based formula engine with dependency graph recalculation. This requires strong knowledge of desktop GUI performance and data structures.
