Awesome CSV

A carefully curated list of CSV-related tools and resources

CSV remains the most futuristic data format from the distant past.

XML has risen and fallen. JSON is just a flash in the pan. YAML is a poisoned chalice. CSV will outlast them all.

When the final cockroach breathes her last breath, her dying act will be to scratch her date of death in a CSV file for posterity.

Footnotes

* I'm the author of NimbleText. Of course I put it first on the list. If I didn't personally rate it I wouldn't have spent so much time making and improving it.

** I wrote agnes but don't really endorse it for others to use (thus haven't migrated the source code to GitHub). It's slow and non-streaming. I'd go with papa-parse. On the plus side, agnes has a more comprehensive test suite and simpler api than most.

*** Mine too.
