Partial The ribbon UI, tabs, and XLSX import/export can be vibe-coded with existing libraries, but a faithful calculation engine with 500+ Excel-compatible functions, dynamic arrays, and LAMBDA plus PivotTables is a very large, precision-sensitive undertaking.
What it would actually take: A real version would combine a grid renderer, a formula parser, and a dependency-graph recalculation engine, possibly in Rust compiled to WebAssembly, with XLSX read/write via an existing library. The hard parts are Excel-compatible semantics, recalculation performance, and PivotTable fidelity, which require spreadsheet-engine expertise and months of focused work.
