This looks like an incredibly powerful tool. I love that it runs in a terminal too! vd input.csv, how easy is that!
VisiData is an interactive multitool for tabular data. It combines the clarity of a spreadsheet, the efficiency of the terminal, and the power of Python, into a lightweight utility which can handle millions of rows with ease.
There are a number of times I've used spreadsheets to move around CSV files. This looks like a much better way to do that.
PS: I find the authors About page delightful. I love this line "I live in Seattle but the terminal is my home." He's building an "ecosystem of textpunk powertools". 🤓💛🖥
