Convert PowerPoint to HTML in Java

In this section, we are going to learn the details on how to load PowerPoint presentation stored in cloud storage and convert it to HTML format.

  • First, we need to create an instance of SlidesApi where we pass the client credentials as arguments.
  • Secondly, create an object of File class and read the content of input PowerPoint file.
  • Now, transform the PowerPoint content to Byte[] array using readAllBytes(…) method.
  • The next step is to upload the PowerPoint to cloud storage using the uploadFile(…) method.
  • Create an instance of HtmlExportOptions where we can specify the presentation’s font information.
  • As we only need to convert the slides at indexes 1 & 3, so we need to create a List object, specifying the index of desired slides.
  • Finally, call the method savePresentation(…) of SlidesApi to convert the PowerPoint to HTML and save the output in the cloud storage.

PPT to HTML using cURL Commands

Another easy approach to convert PowerPoint to HTML is by accessing the Aspose.Slides Cloud API using cURL commands. This approach offers several benefits, including increased accessibility, improved compatibility, and enhanced sharing options. Therefore, the use of cURL commands enables you to automate the conversion process, making it ideal for large-scale or repetitive conversions. Furthermore, you can easily incorporate the commands into your workflows or scripts to achieve efficient and streamlined conversions.

When using this approach, the first step is to generate a JWT access token by executing the following command:

curl -v "https://api.aspose.cloud/connect/token" \
-X POST \
-d "grant_type=client_credentials&client_id=bbf94a2c-6d7e-4020-b4d2-b9809741374e&client_secret=1c9379bb7d701c26cc87e741a29987bb" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Now, we need to execute the following command to load a PowerPoint presentation from cloud storage and convert it to HTML format. With this approach, we are going to save the resultant HTML on the local drive.

curl -v -X POST "https://api.aspose.cloud/v3.0/slides/Resultant.ppt/Html" \
-H  "accept: multipart/form-data" \
-H  "authorization: Bearer <JWT Token>" \
-H  "Content-Type: application/json" \
-d "{  \"DefaultRegularFont\": \"string\",  \"FontFallbackRules\": [    {      \"RangeStartIndex\": 0,      \"RangeEndIndex\": 0,      \"FallbackFontList\": [        \"string\"      ]    }  ],  \"Format\": \"string\"}"

Conclusion

In conclusion, whether you opt for the convenience of cURL commands or the comprehensive features of the Aspose.Slides Cloud SDK for Java, converting PowerPoint to HTML has never been easier. With cURL commands, you have the flexibility to customize the conversion process, fine-tuning settings and parameters to meet your specific requirements. On the other hand, the Aspose.Slides Cloud SDK for Java provides a comprehensive set of tools and features specifically designed for PowerPoint to HTML conversion.
