Papa Parse (via) I’ve been trying out this JavaScript library for parsing CSV and TSV data today and I’m very impressed. It’s extremely fast, has all of the advanced features I want (streaming support, optional web workers, automatically detecting delimiters and column types), has zero dependencies and weighs just 19KB minified—6.8KB gzipped.
The project is 11 years old now. It was created by Matt Holt, who later went on to create the Caddy web server. Today it’s maintained by Sergi Almacellas Abellana.
