HTML to PPTX and PPT: Convert Web Pages with cURL

HTML holds headings, paragraphs, tables and images marked up for a browser. A presentation needs the same material in a form PowerPoint can open and edit, and rebuilding it by hand loses the tables and the pictures first.

The conversion is common where the content is already published on the web: a documentation page that has to be shown at a meeting, an email newsletter kept as HTML, or a report generated by a tool that only writes markup.

GroupDocs.Conversion Cloud reads the HTML file and writes PPTX or PPT. The whole document or a range of pages can be converted, the output quality is adjustable, and the deck can be watermarked or password protected before it is returned.

From cURL this is a single command carrying your Client ID and Secret, which fits a shell script, a makefile or a build step. A free online converter takes one file without any code, and the API Explorer shows the parameters.
