If you do not need to save data anywhere and immediately give the XLS
Controller

class XlsController < ApplicationController
 # В index вьюшке выводим фарму
  def index
  end
  # Тут получаем POST запрос с данными формы и формируем XLS
  # routes.rb - post 'xls/get_xls'
  def get_xls
    filename = "form-#{Time.now.strftime("%Y%m%d%H%M%S")}.xls"
    send_data([validate_params].to_xls, :type => "text/xls; charset=utf-8; header=present", :filename => filename)
  end
  private
  # Валидация формы
  def validate_params
    params.require(:form).permit(:value1, :value2)
  end
end

View

<%= form_tag xls_get_path, method: "post" do %>
    <p><%= label_tag('VALUE1') %></p>
    <p><%= text_field_tag('form[value1]') %></p>
    <p><%= label_tag('VALUE2') %></p>
    <p><%= text_field_tag('form[value2]') %></p>
    <p> <%= submit_tag('SEND') %></p>
<% end %>
