Answer 1

I think your problem might be that your show_proov function is returning an array of arrays. [["file1"], ["file2"], ["file3"]] This is because String.scan returns an array. Try adding .first, like so: xlsxfiles = files.find_all {|file| file.include?('.xlsx') }.map do |file| file.scan(/^\w+/).first end Then the result will be: ["file1", "file2", "file3"]
