Build a presentation from content you already have

Most of the presentation work people automate runs into a deck rather than out of one: pulling HTML, images, PDF pages or database rows onto slides. Aspose.Slides reads HTML markup straight into a text frame, keeping the headings, bold runs and lists it finds.

That is the whole program: no PowerPoint, no headless Office, no template file to keep in step. The same call takes markup a reporting job or a content system already produces, so an existing HTML report becomes a deck on a schedule instead of by hand.

HTML → PPTXPYTHON

import aspose.slides as slides

html = "<h1>Quarterly review</h1><p>Revenue up <b>18%</b> on the quarter.</p>"

with slides.Presentation() as presentation:
    frame = presentation.slides[0].shapes.add_auto_shape(
        slides.ShapeType.RECTANGLE, 40, 40, 640, 300).text_frame
    frame.paragraphs.clear()
    frame.paragraphs.add_from_html(html)
    presentation.save("quarterly.pptx", slides.export.SaveFormat.PPTX)

Start with the trial, license when you ship

The trial is the full API. It applies an evaluation watermark when a presentation is opened or saved and caps text extraction at one slide, so you can test the formats you actually care about before you talk to anyone. A temporary licence lifts both for 30 days.

The product worked as advertised, the documentation was easy to follow, and the support forums were all the help we needed. The final solution that we deployed has exceeded our initial expectations by a great deal.
