Ruby2xlsx¶ ↑

Export your data to Excel. Provide two ways for export data: template or renderer.

Add gem to your Gemfile:

gem "ruby2xlsx"

You can use two types: template and renderer.

def index
  @articles = Article.order('id DESC')

  respond_to do |format|
    format.html # index.html.erb
    format.xlsx { render xlsx: @articles }
  end
end

With options:

format.xlsx { render xlsx: @articles,
  :columns => [:id, :title, :updated_at],
  :filename => ["articles_", Time.now.to_s, ".xlsx"].join,
  :worksheet_name => "My articles" }

In controller (app/controllers/articles_controller.rb):

class ArticlesController < ApplicationController
  respond_to :xlsx, :only => [:index]

  def index
    @articles = Article.order('id DESC')
    @xlsx_filename = "some_file_name"

    respond_with(@articles)
  end
end

In view (app/views/articles/index.xlsx.xrb):

add_worksheet "Data"

bold = add_format(:bold => 1)
headings = [ 'Title', 'Views', 'Comments' ]

write('A1', headings, bold)

@articles.each_with_index do |article, index|
  row = index + 1
  write(row, 0, article.title)
  write(row, 1, article.views_count)
  write(row, 2, article.comments_count)
end

chart4 = add_chart(:name => 'Results Chart', :type => 'Chart::Area')

# Configure the series.
chart4.add_series(
    :categories => '=Sheet1!$A$2:$A$7',
    :values => '=Sheet1!$B$2:$B$7',
    :name => 'Test data series 1'
)

# Add another series.
chart4.add_series(
    :categories => '=Sheet1!$A$2:$A$7',
    :values => '=Sheet1!$C$2:$C$7',
    :name => 'Test data series 2'
)

# Add some labels.
chart4.set_title( :name => 'Results of sample analysis' )
chart4.set_x_axis( :name => 'Sample number' )
chart4.set_y_axis( :name => 'Sample length' )
