Copilot Prompt for PowerPoint Automation

I have a Microsoft PowerPoint slide deck that serves as our house template and an XLSX workbook that holds all the text blocks and data tables I want surfaced in that deck. What I need from you is a well-structured Microsoft 365 Copilot prompt (or prompt set) that automatically:

• Reads my XLSX file
• Injects each text element and table into the correct placeholders on the template
• Exports a finished .pptx ready for review

Key details
• Source file format: XLSX only—no CSV or ODS support required.
• Target platform: Microsoft PowerPoint; the template is already built and will be supplied.
• Content types involved: pure text and formatted tables (no charts this round).

Deliverables
1. The final Copilot prompt(s) with clear inline comments explaining each step.
2. A concise setup note so I can point Copilot to the template path and workbook.
3. A quick demo run—screenshots or a short screen-capture video—showing the prompt turning the sample XLSX into the matching deck.

Acceptance criteria
• Running the prompt on the provided sample files produces a slide deck with every text field and table in its correct slide and style.
• No manual touch-ups needed other than optional proofreading.

If you have previous experience scripting Copilot for Office or using OpenAI functions with Office JS, mention it in your bid so I know this will be a smooth collaboration.
