Papa Parse is a fast and powerful CSV parser for JavaScript.

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-detect the delimiter
  • Worker threads to keep your web page reactive
  • Header row support
  • Pause, resume, abort
  • Can convert numbers and booleans to their types
  • Graceful and robust error handling
  • Minor jQuery integration to get files from <input type="file"> elements
  • Papa Parse has no dependencies - not even jQuery.

Visit the Papa Parse project page on GitHub.
