Similar is visidata. It's also a vim-like, but is geared specifically at tabular/relational data, so not a spreadsheet app in the strict sense. However, it can access SQL databases, and has a very flexible / intuitive approach to trasformations.
I've been using sc a few times. It's great to have an improved version!

Wow, does this mean I can use those "computing modules" that customers invariably give me in the form of XLSX sheets (with input and output cells) without having to use one of those huge Java libraries? This is awesome!
And the original SC version was written by James Gosling, the guy who went on and invented Java. I happened to attended a talk by him recently. To my surprise, the guy mentioned very little about Java, which I thought to be his greatest achievement. For most of the talk, James just discussed his work in space-communication technology and the development of an autonomous marine-time vehicle in his recent employment. He went on and talked about the IOT devices and felt annoyed that people think that they could shove NodeJS or Python code to a embedded device.
It's amazing that I feel like he's still pretty much interested in doing the daily developing/debugging: his eyes were lit up when he talked about debugging the autonomous vehicle underwater in Hawaii.
yay, gave me flashback to wordstar. I remember seeing a coming soon poster for total recall the day I tried to learn it on some weird cp/m box I got for free.
