Could you build this?
Partial Designing a DSL or text schema is straightforward, but creating a fully functional bi-directional converter that preserves complex Excel formulas, formatting, sheets, and cell types requires deep knowledge of the OpenXML/BIFF specifications.
What it would actually take: A complete implementation requires building parsers and serializers in a language like Python or Rust that interface with libraries like openpyxl or calamine/rust_xlsxwriter, or parsing raw OpenXML zip containers directly. The hard part is accurately round-tripping complex spreadsheet features such as formula ASTs, cell data formatting strings, shared strings, and multi-sheet references without data loss. It requires thorough knowledge of spreadsheet specification standards and edge-case regression test suites.
