Not sure how to start? Tell me what you're trying to get done and I'll help you turn it into a clear request.

Goal: Build a DCF (discounted cash flow) valuation model for Nvidia, delivered as a downloadable Excel spreadsheet.

Quick check first: Is this for learning, or do you have your own assumptions you'd like me to use?

What I need from you:
- The company (Nvidia here)
- Any assumptions you want me to use, like growth or discount rate

Rules:
- Walk through each assumption and explain your steps.
- Build the spreadsheet with working formulas, not just pasted numbers.
- If something is missing or unclear, ask me instead of guessing.
- This is a model to check and edit, not investment advice.

Output: A downloadable Excel file with formulas, assumptions and the resulting valuation, plus a short explanation.

If any of this is unclear, tell me what you have and I'll help fill the gaps.

You'll know it worked when: you can open the file, change an assumption, and see the valuation update.

Works best when: you plan to verify and adjust the assumptions afterward.
