Using cURL commands for HTML to PowerPoint (PPTX) conversion offers several advantages, particularly for developers and businesses looking for a quick, automated, and scriptable approach to document transformation. It’s lightweight & fast, has cross-platform compatibility, it’s secure & scalable and requires minimal coding effort.

The first step in this approach is to generate a JWT access token and then, execute the following cURL command to insert the webpage into a PowerPoint presentation and save the resultant PowerPoint in cloud storage.

curl -v "https://api.groupdocs.cloud/v2.0/conversion" \
-X POST \
-H "accept: application/json" \
-H "authorization: Bearer {accessToken}" \
-H "Content-Type: application/json" \
-d "{  \"StorageName\": \"default\",  \"FilePath\": \"{sourceHTML}\",  \"Format\": \"PPT\",  \"OutputPath\": \"{resultantFile}\"}"

Please replace sourceHTML with the name of input HTML file, OutputPath with the name of resultant PowerPoint presentation and accessToken with personalized JWT access token.
