opencsv is a simple csv (comma-separated values) parser library for Java

What is opencsv ?

opencsv is a simple csv (comma-separated values) parser library for Java. It was developed in response to a lack of csv parsers with commercial-friendly licenses.

Where can I get it?

Source and binaries are available from Sourceforge. You can check out the javadocs online.

What features does opencsv support?

opencsv supports all the basic csv-type things you're likely to want to do:

  • Arbitrary numbers of values per line
  • Ignoring commas in quoted elements
  • Handling quoted entries with embedded carriage returns (ie entries that span multiple lines)
  • Configurable separator and quote characters (or use sensible defaults)
  • Read all the entries at once, or use an Iterator style model
  • Creating csv files from String[] (ie. automatic escaping of embedded quote chars)
