Using Active Admin?

You are going to love this:

Just the facts [gender neutral honorific]

Put this in your Gemfile

gem 'activeadmin-axlsx'

That's it. You are done.

And because I love you so much, there are a few toys you should know about too:

Localize your column headers!

config.xlsx_builder.i18n_scope [:active_record, :models, :posts]

Pass in blocks for calculated fields!

config.xlsx_builder.column('author_name') do |resource|
  resource.author.name 
end

Customize your header row style!

config.xlsx_builder.header_style = { :bg_color => 'FF0000', :fg_color => 'FF' }

I get wanting JSON or XML data downloads but can we please stop using CSV for reporting?
