Given below is the explanation of above stated code snippet.

SlidesApi slidesApi = new SlidesApi(clientID, clientSecret);

Create an instance of SlidesApi class where we pass the client credentials as arguments.

var responseStream = slidesApi.DownloadPresentation("Summer invitations.pptx", ExportFormat.Html);

Call REST API to convert PowerPoint slides to HTML format and return the output as Stream object.

using var pdfStream = File.Create("converted.html");
responseStream.CopyTo(pdfStream);

By default, all the slides of PowerPoint presentation are converted but in case you need to convert only specific slides, please provide the details via List object. Please take a look over the following code line, which only converts 2nd and 3rd slide of the presentation.

var responseStream = slidesApi.DownloadPresentation("Summer invitations.pptx", ExportFormat.Html, null, null, null, null, null, new List<int> {2,3});

The PowerPoint presentation used in the above example can be easily downloaded from Summer invitations.

If you prefer a command-line approach, you can leverage the flexibility of cURL commands to convert PPTX to HTML effortlessly. By making use of the Aspose.Slides Cloud API, you can send HTTP requests with cURL and perform the conversion with ease. This method provides a straightforward and an efficient way to automate the conversion of PowerPoint presentations to webpage, making it accessible and compatible with various web platforms.

Now, in order to begin with this approach, first execute the following command to generate an accessToken based on your client credentials.

curl -v "https://api.aspose.cloud/connect/token" \
 -X POST \
 -d "grant_type=client_credentials&client_id=ee170169-ca49-49a4-87b7-0e2ff815ea6e&client_secret=7f098199230fc5f2175d494d48f2077c" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Once the JWT access token has been generated, please execute the following command to convert PowerPoint to HTML online. Please note that in the following command, we are only converting the 3rd slide of the presentation.

curl -v "https://api.aspose.cloud/v3.0/slides/{inputPPT}/Html?slides=3" \
-X POST \
-H  "accept: multipart/form-data" \
-H  "authorization: Bearer {accessToken}" \
-H  "Content-Type: application/json" \
-d "{}" \
-o "{resultantHTML}"

Replace {inputPPT} with the name of PowerPoint available in cloud storage. Then replace {accessToken} with JWT access token and {resultantHTML} with the name of the resultant HTML file to be stored on local drive.
