At work, I work with a lot of CSVs. I often hit the limit of Excel and Google Sheets. Plus, using formula is difficult. The ergonomics around it is also not great (e.g. am I suppose to write long formula in a one-line box at the top?)

Eventually, I've decided to create Superintendent that enables me to write SQL on CSVs.

I'm working on optimizing it to be faster and faster. Currently, it can load 1GB CSV on Mac Pro 2020 within 10 seconds because it basically goes to C code.

I'm looking to make it feel more and more like a spreadsheet (e.g. click to sort, copy row, copy column, edit it directly) while giving focus to SQL writing. I'm loving it so far, but there are still a lot of improvements to be made.
