TermRemarkable665 · reddit · 2026-11-04
A developer shares how they used ChatGPT to turn raw Excel data into a lightweight HTML/JS dashboard with country-level metric cards, dynamic filters, Excel upload-to-refresh, and two-way map syncing (click table → highlight map, click map → detail cards).
Key takeaways:
- Prompting the LLM to write local Excel parsing logic keeps the frontend reusable across reporting cycles
- Two-way map sync was the hardest part
- Full prompt and a 2-minute walkthrough video are shared
Aimed at anyone tired of emailing Excel or paying for Power BI licenses for stakeholders.
