How to Convert DOCX to PDF Using Aspose.Words?

Follow the instructions given below to perform the MS Word files DOCX to PDF conversion using Ruby SDK for ruby on rails application.

  1. The first step is to create ruby variables holding ClientID and ClientSecret copied from the aspose cloud dashboard.
  2. At second, create AsposeWordsCloud configuration and pass ClientID, ClientSecret values.
  3. Third step is to create an instance of WordsAPI
  4. Next, upload source DOCX file to cloud storage using UploadFileRequest() method
  5. Now, create an object of ConvertDocumentRequest() which takes input DOCX name, resultant format as arguments
  6. Finally, initiate DOCX to PDF conversion process with the convert_document() method.
# Load the gem, please go to https://github.com/aspose-words-cloud/aspose-words-cloud-ruby
require 'aspose_words_cloud'
# How to convert Word to PDF programmatically.
# Get AppKey and AppSID credentials from https://dashboard.aspose.cloud/applications
@app_client_id = "######-####-####-####-#########"
@app_client_secret = "##########################"
# Associate Configuration properties with WordsApi
AsposeWordsCloud.configure do |config|
  config.client_data['ClientId'] = @app_client_id
  config.client_data['ClientSecret'] = @app_client_secret
end
# Create an instance of WordsApi
@words_api = WordsAPI.new
# Input DOCX file
@fileName = "mysample.docx"
# Final file format
@format = "pdf"
# Upload the original document to your selected cloud storage
@words_api.upload_file UploadFileRequest.new(File.new(@fileName, 'rb'), @fileName, nil)
# Define document conversion parameters initialize(document, format, out_path, file_name_field_value, storage, fonts_location)
@request = ConvertDocumentRequest.new(File.new(@fileName, 'rb'), @format, nil, nil, nil, nil)
# Initiate DOCX to PDF conversion process
@result = @words_api.convert_document(@request)
puts @result.to_s.inspect
# Print result response in console
puts("Document successfully converted to pdf")
# End document converting example

As a result mysample.pdf will be saved at the root of project folder.

How to Use cURL for DOC to PDF Conversion?

Now let’s examine how to convert a word document to pdf using cURL. cURL command line tool is used to access REST APIs to and from a server. Since Aspose.Words Cloud APIs are developed as per REST principles, so we can use these Cloud APIs to do the conversion operations. To perform conversion, we will generate JSON Web Token (JWT) based on ClientID and ClientSecret retrieved from Aspose.Cloud dashboard. Please execute the command in the terminal to generate the JWT token like below.

curl -v "https://api.aspose.cloud/connect/token" \
-X POST \
-d "grant_type=client_credentials&client_id=######-####-####-####-######&client_secret=#########################" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Next, add the JWT token in below command to convert the DOC file to PDF format and the input DOCX file should be available on cloud storage. Then outPath parameter shows the location for the resultant PDF document and the format is the format of the resultant pdf file. GetDocumentWithFormat API is for document conversion and doc-to-pdf.doc file is rendered to PDF format successfully. You can check saved file with doc-to-pdf.pdf name in cloud storage.

curl -X GET "https://api.aspose.cloud/v4.0/words/test_multi_pages.docx?format=pdf&outPath=doc-to-pdf.pdf" \
-H  "accept: application/octet-stream" \
-H  "Authorization: <PASTE HERE JWT Token>"

Conclusion

In the above article, we have explained the steps for how to convert DOCX file to PDF file using Aspose.Words Cloud SDK for Ruby. Aspose Cloud SDKs are open-source software and the complete code of Aspose.Words cloud SDK for Ruby is available on GitHub.
