results = []
rows = 9
columns = 8

File.open ("data.txt") do |f|
  lines = f.readlines

  (0...columns).each do |column|
    string = ""

    (0...rows).each do |row|
      next if lines[row][column] == " "
      string << lines[row][column]
    end

    results.push string
  end

end

p results



--output:--
["NAMEONE", "NAMETWO", "NAMETHREE", "NAMEFOUR", "NAMEFIVE", "NAMESIX", 
"NAMESEVEN", "NAMEEIGTH"]
