I need a language check here, new to DuckDB

About "database client?" I would just call it a database, I think client is something that connects to an actual database.

maybe add a link for the xlsx format and its options https://observablehq.com/@observablehq/xlsx?collection=@observablehq/getting-data-in-and-out

@cobus do you think this works here too?

Not sure we need it on links like that... it could deter them from clicking on it. I think it works well if it is on the destination notebook.
