+# write\_xlsx\_rails
+
+Gem for generate Excel files from Rails views with [write\_xlsx](https://github.com/cxn03651/write_xlsx).
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'write_xlsx_rails'
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install write_xlsx_rails
+
+## Usage
+
+write\_xlsx\_rails provides a renderer and a template handler. It adds the :xlsx format and parses .xlsx.wxlsx templates.
+
+###Controller
+
+You can either use the typical format:
+
+```ruby
+respond_to do |format|
+  format.xlsx
+end
+```
+
+or call render directly:
+
+```ruby
+render xlsx: "foobar", filename: "annual-report", disposition: 'inline'
+```
+
+If you merely want to specify a file name, you can do it one of two ways:
+
+```ruby
+format.xlsx {
+	response.headers['Content-Disposition'] = 'attachment; filename="my_new_filename.xlsx"'
+}
+```
+
+or
+
+```ruby
+format.xlsx {
+  render xlsx: "action_or_template", disposition: "attachment", filename: "my_new_filename.xlsx"
+}
+```
+
+> NOTE: Someday it would be nice to merely say something like:
+	render :filename, 'blah.xlsx"
+
+###Template
+
+Use the .xlsx.wxlsx extension in the template, use `workbook` variable, which is set with WriteXLSX.new:
+
+```ruby
+# Add a worksheet
+worksheet = workbook.add_worksheet
+
+# Add and define a format
+format = workbook.add_format # Add a format
+format.set_bold
+format.set_color('red')
+format.set_align('center')
+
+# Write a formatted and unformatted string, row and column notation.
+col = row = 0
+worksheet.write(row, col, "Hi Excel!", format)
+worksheet.write(1,   col, "Hi Excel!")
+
+# Write a number and a formula using A1 notation
+worksheet.write('A3', 1.2345)
+worksheet.write('A4', '=SIN(PI()/4)')
+```
+
+If you use [acts\_as\_xlsx](https://github.com/randym/acts_as_xlsx), configure the active record normally, but specify the package in the template:
+
+```ruby
+User.to_xlsx package: xlsx_package, (other options)
+```
+
+####Partials
+
+Partials work as expected:
+
+```ruby
+render partial: 'header', locals: { worksheet: worksheet }
+```
+
