CsvEncodingHelper

A Ruby gem that automatically detects and converts CSV file encodings (UTF-8, UTF-16LE/BE, Shift_JIS, EUC-JP, ISO-2022-JP) into UTF-8.

Add this line to your application's Gemfile:

gem "csv_encoding_helper"

And then execute:

bundle install

Or install it yourself:

gem install csv_encoding_helper

require "csv_encoding_helper"

file = File.binread("sjis.csv")
uft8_text = CsvEncodingHelper::Decoder.decode(file)
CSV.parse(utf8_text, headers: true)
