Use python-pptx to build a .pptx file entirely in code by adding slides from layouts, setting title and body text, inserting tables, and saving to disk. Install it with pip install python-pptx and call prs.save() to write the file.

Load the workbook with openpyxl using data_only=True, resolve named ranges through wb.defined_names, and insert those computed values into slide text. Recalculate the workbook first, since openpyxl only reads values that have already been computed.

Native pptx.chart charts are fragile and often do not match firm styling conventions. Rendering the chart to PNG from the source workbook and embedding it with slide.shapes.add_picture preserves exact visual fidelity between model and deck.

Yes, load an existing .pptx template by passing its path to Presentation(), and the new deck inherits the template's branded colors, fonts, and master layouts. The skill checks for ./templates/firm-template.pptx and falls back to a blank presentation.

Avoid it when a user is in a live PowerPoint session with an Office MCP available, or when the deck needs heavy animations, transitions, or speaker notes. Those cases call for driving the live document or a broader presentation skill.
