OnlyCSharp.Sheets — a real formula engine, wired
Every Total below is computed at build time by the OnlyCSharp 3.0 ComputerScience.Fast.Sheet.OcSheet engine — A1-style cell references, arithmetic, and dependency recalculation — not a typed-in number and not a re-implemented evaluator. Green cells are formulas; their source is shown beneath the value. Authored as .razor, rendered to static HTML.
| A | B | C | D | |
|---|---|---|---|---|
| 1 | Item | Qty | Price | Total |
| 2 | Apples | 3 | 2 | 6=B2*C2 |
| 3 | Bread | 5 | 4 | 20=B3*C3 |
| 4 | Coffee | 2 | 10 | 20=B4*C4 |
| 5 | Total | 46=D2+D3+D4 |

Edit
the engine recomputes every dependent automatically:
B2 (Apples qty): 3 → 10the engine recomputes every dependent automatically:
D2 =B2*C2: 6 → 20D5 =D2+D3+D4: 46 → 60
