Parse CSV with Javascript

mholt on Gittip

Papa Parse (formerly the jQuery Parse Plugin) is a robust and powerful CSV (character-separated values) parser with these features:

  • Easy to use
  • Parse CSV files directly (local or over the network)
  • Stream large files (even via HTTP)
  • Reverse parsing (converts JSON to CSV)
  • Auto-detects the delimiter
  • Worker threads to keep your web page responsive
  • Header row support
  • Can convert numbers and booleans to their types
  • Graceful and robust error handling
  • Minor jQuery integration to get files from <input type="file"> elements

All are optional (except for being easy to use).

Demo

Get Started

Papa Parse is under test (especially its core Parser). Download this repository and open tests/tests.html in your browser to run them.

Contributing

To discuss a new feature or ask a question, open an issue. To fix a bug, submit a pull request to be credited with the contributors! Remember, a pull request, with test, is best. (Especially all changes to the Parser component should be validated with tests.) You may also discuss on Twitter with #PapaParse or directly to me, @mholt6.

Origins

Papa Parse is the result of a successful experiment by SmartyStreets which matured into a fully-featured, independent Javascript library.
