There's a ton of mindnumbing testing and grinding work that honestly no one really wants to do, involving bit-level accuracy in many cases. We (https://sheetjs.com/) are attacking the file compatibility problem (our major open source project is https://github.com/sheetjs/js-xlsx, used in stencila's spreadsheet converters) and it is painfully obvious that OO/LO cuts corners at certain places. For example, the mathematics of Calc is intentionally bugged:
