Efficient lazy parsers for CSV (comma-separated values).

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow to host generated Haddocks.

The CSV format is defined by RFC 4180. These efficient lazy parsers (String and ByteString variants) can report all CSV formatting errors, whilst also returning all the valid data, so the user can choose whether to continue, to show warnings, or to halt on error. Valid fields retain information about their original location in the input, so a secondary parser from textual fields to typed values can give intelligent error messages.
