Excel add-in preview
Compare energy prices with refreshable Excel formulas
The Excel workflow we are standardizing on is the OilPrice add-in: set an API key, use formula inputs in the workbook, and recalculate from inside Excel after validation.
Preview scope
- API key manager in the add-in pane
- Refreshable formulas for core energy price lookups
- Plain worksheet errors for auth, quota, tier, and no-data states
- Production Excel smoke before customer instructions
Formula model
Customers should be able to change symbols and inputs directly in Excel, then recalculate without switching tools.
