Visidata[0] is a killer data swiss army knife. It's even inspired off Visicalc

It's weird but visidata is my favorite spreadsheet.

"But... visidata is not a spreadsheet"

I know, that's what makes it so weird.

On contemplation, I think I grew dissatisfied with the normal spreadsheet data model, I wanted something bettered structured than the "it's a big bag of cells" that spreadsheets present, I wanted row security. The best I found was the relational database. I currently use a local postgres db for most things I would have used a spreadsheet for. The interfaces sort of suck in comparison but at least I have sane data structures.
