Character Enumerator

Ruby enumerator that converts integers to character representation(Like in Microsoft Excel - A, B, C, .. Z, AA, AB)

Add this line to your application's Gemfile:

gem 'character_enumerator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install character_enumerator

CharacterEnumerator.integer_to_characters(0) # => "A"
CharacterEnumerator.integer_to_characters(0) # => "A"
CharacterEnumerator.integer_to_characters(1) # => "B"
CharacterEnumerator.integer_to_characters(25) # => "Z"
CharacterEnumerator.integer_to_characters(26) # => "AA"
CharacterEnumerator.integer_to_characters(27) # => "AB"
CharacterEnumerator.integer_to_characters(51) # => "AZ"
CharacterEnumerator.integer_to_characters(52) # => "BA"
CharacterEnumerator.integer_to_characters(200_000) # => "KIVI"

# Will print A, B, C, D, E
CharacterEnumerator.generate(5).each do |char|
  puts char
end
