How to convert PowerPoint PPTX to PDF in Ruby

The title speaks for itself, so let’s dive straight in. First, add the Convert API Client to your Gemfile.

gem 'cloudmersive-convert-api-client', '~> 1.3.3'

Then call convert_document_autodetect_to_pdf, as follows:

# load the gem
require 'cloudmersive-convert-api-client'
# setup authorization
CloudmersiveConvertApiClient.configure do |config|
  # Configure API key authorization: Apikey
  config.api_key['Apikey'] = 'YOUR API KEY'
  # Uncomment the following line to set a prefix for the API key, e.g. 'Bearer' (defaults to nil)
  #config.api_key_prefix['Apikey'] = 'Bearer'
end
api_instance = CloudmersiveConvertApiClient::ConvertDocumentApi.new
input_file = File.new("/path/to/file") # File | Input file to perform the operation on.
begin
  #Convert Document to PDF
  result = api_instance.convert_document_autodetect_to_pdf(input_file)
  p result
rescue CloudmersiveConvertApiClient::ApiError => e
  puts "Exception when calling ConvertDocumentApi->convert_document_autodetect_to_pdf: #{e}"
end

And you’re done! Simple right? Note that this function is not limited to PowerPoint files, covering virtually any format you desire.
