How the conversion works
A typical pipeline reads the report with its headings and tables, drafts an outline of slides, writes the text and speaker notes for each, picks a layout, and writes a .pptx file. PPTAgent, a 2025 research system, works by analysing example presentations and then editing reference slides, rather than drawing layouts from nothing, and evaluates the result on content, design and coherence.
The file format is Office Open XML, an open standard published as ECMA-376 and ISO/IEC 29500, which is a ZIP package of XML. The python-pptx library can create, read and update .pptx files, add slides, fill the text placeholders of an existing template, and add pictures, tables and charts. Because the output is a normal PPTX file, it opens in PowerPoint and in other tools that import the format.
