it is better than messing around with vlookup (what isn't), but only a tiny subset of sql is supported (with dedicated syntax). Also it claims to support actual human readable column names but as far as I know it doesn't work and you have to use column labels. Also no joins.
Still, if it were to be extended to a full query language with good ergonomic it would be amazing.
1. It's writing a query in a single row cell which is hard from a UX perspective
2. SheetSQL offers you a way to cross join sheets as if those where tables, even between worksheets, which is something that is not supported natively
3. Full DuckDB SQL support, so you can use advanced functions like PIVOT or window functions
