- Worth noticing
- The audit view pairs a model’s named formula with the Excel formula and highlights the cells it reads.
Field notes
The example defines an operations module with capacity, capacity factor, availability, degradation, and tariff feeding energy and revenue calculations. The audit view is described as tracing a selected value back to its .rfn source line and showing both the named expression and its Excel formula, alongside the cells it reads. The homepage identifies the editor, checks, and preview as free, while reserving Excel export for Pro.
