FastExcelRails

A Rails template handler for the fast_excel gem.

Add this line to your application's Gemfile:

gem "fast_excel_rails"

And then execute:

$ bundle install

The default template file for your controller action can be rendered using format.xlsx:

class ThingsController < ApplicationController
  def index
    @things = (1..1000).to_a
    respond_to do |format|
      format.xlsx
    end
  end
end

Other options, like filenames or custom template paths, can be set using an explicit render call:

class ThingsController < ApplicationController
  def index
    respond_to do |format|
      format.xlsx { render :xlsx => "my filname.xlsx", :template => "custom_template"
    end
  end
end

Templates use the .xlsx.fast_excel extension and are normal Ruby files that have access to a workbook variable that is a FastExcel::Workbook instance.

For example, app/views/things/index.xlsx.fast_excel:

worksheet = workbook.add_worksheet

worksheet.append_row(["Message", "Price", "Date"], workbook.bold_format)

@things.each do |i|
  worksheet << ["Hello", (rand * i).round(2), Time.now])
end

See fast_excel for further information on usage syntax.
