Parse CSV with Javascript

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

• Parses delimited text strings without any fuss
• Attach to <input type="file"> elements to load and parse files from disk
• Automatically detects delimiter (or specify a delimiter yourself)
• Supports streaming large inputs
• Utilize the header row, if present
• Gracefully handles malformed data
• Optional dynamic typing so that numeric data is parsed as numbers
• Descriptive and contextual errors

Origins

Papa Parse is the result of an experiment by SmartyStreets which matured into a fully-featured, independent jQuery plugin. Wanting to enhance the demo on their homepage, SmartyStreets looked into ways to simulate their list service. This involved processing at least part of a potentially large delimited text file. And what else? They wanted to do it without requiring a file upload (for simplicity and to alleviate privacy concerns). No suitable solutions were found, so they built their own. After finding it successful, the code was brought out into this jQuery plugin, now known as Papa Parse.
