xsv

xsv is a command line program for indexing, slicing, analyzing, splitting and joining CSV files. Commands should be simple, fast and composable:

1. Simple tasks should be easy.
2. Performance trade offs should be exposed in the CLI interface.
3. Composition should not come at the expense of performance.

I recently needed to scrape a website and output different values on a page into a CSV for easier consumption by other people at work. The biggest hassle is of course taking multiline strings and putting them into a csv file. On every iteration of my script, I started by opening up Numbers (😵) and examining the result but that became very onerous. With xsv's nicely formatted command line output I could rerun my extraction script and then verify the csv output without leaving the command line. 10/10 would use this to csv again.
