This looks awesome. I'm the target audience. I do quite a bit of development around SQL Server and there's an endless stream of CSV and XLSX files coming and going that need spot checks and quick looks. I use ModernCSV quite a bit and would have purchased that if it built these SQL features in. I've used DuckDB directly a few times to join and query CSV and XLSX files, I'll pay my own $$ for something that quickly streamlines this.

I can import into SQL Server but there's too much ceremony needed (column types, etc) for quick looks at data I'm going to answer a question about and then discard. After a quick look at TextQuery I'm running into the same issues (although TextQuery is just a couple of clicks instead of 5+). I was also seeing an error yesterday from associating XLSX files with TextQuery but that seems to have gone away today.
