CSV::Excel

CSV::Excel extends Ruby's csv stdlib to generate CSV file for Microsoft Excel. This converts...

• Time/Date/DateTime object to Excel's date/time format (yyyy/mm/dd, yyyy/mm/dd hh:mm:ss).
• String to ="foo" form for avoiding unexpected type casting (eg. Zero leading phone number, hyphen delimited street address).

Installation

Add this line to your application's Gemfile:

gem 'csv-excel'

And then execute:

$ bundle

Or install it yourself as:

$ gem install csv-excel

Usage

require "csv/excel"

buffer = ""

csv = CSV.new(buffer, for_excel: true)
csv << ["012", "12", "🍣", 123, Date.new(2019, 4, 1), Time.new(2019, 4, 1, 12, 34, 56)]

# Excel reads csv as Shift_JIS by default.
# Please add BOM to indicate UTF-8 encoding.
File.write("out.csv", CSV::Excel::UTF8BOM + buffer)

# Open Finder/Explorer, and double-click `out.csv`!
