Could you build this?

No A high-performance spreadsheet engine requires complex formula parsers, topological sorting for cyclic/acyclic dependency graphs, sparse matrix storage, and low-level Rust/WASM memory optimization.

What it would actually take: The engine needs a custom formula lexer/parser, an incremental calculation DAG (directed acyclic graph) evaluator, and virtualized memory structures to handle millions of cells at 60 FPS in WASM. Building this requires deep systems programming, algorithmic graph theory, and compilers expertise.
