CsvParser

CsvParser is a CSV parser that focuses on identifying errors.

Add this line to your application's Gemfile:

gem 'csv_parser'

And then execute:

$ bundle

Or install it yourself as:

$ gem install csv_parser

CsvParser's goal is to give you descriptive error messages.

• missing closing quote (CsvParser::MissingQuoteError)
• quote in the wrong place (CsvParser::StrayQuoteError)
• rows with not enough fields (CsvParser::MissingFieldsError)
• rows with too many fields (CsvParser::ExtraFieldsError)

You can pass in an options hash to the CsvParser.parse method that contains one or more of the following options:

• :field_sep - specify field separator (default is ",")
• :record_sep - specify record separator (default is "\n")
• :quote_char - specify quote character (default is "\"")
• :allow_empty_record - specify whether empty records are allowed (default is true)
• :skip_empty_record - specify whether empty records are skipped (default is true)
• :allow_uneven_records - specify whether records with different field lengths are allowed (default is true)

require 'csv_parser'

data = <<EOF
foo,"bar
baz,quz
EOF
begin
  result = CsvParser.parse(data)
rescue CsvParser::Error => e
  # e is a CsvParser::MissingQuoteError
end
