SolveSheet

Intelligent constraint solver for Google Sheets — multi-variable Goal Seek, scenarios, sensitivity analysis

SolveSheet brings constraint-solving to Google Sheets — no Excel, no add-ons, no data leaving your device. ── GOAL SEEK (Free) ── Select any formula cell, set a target value, and SolveSheet finds the input values that get you there. Works across formula chains of any depth. Shortcut: ⌘⌥G (Mac) / Ctrl+Alt+G (Windows) ── MULTI-VARIABLE SOLVER (Pro) ── Set multiple simultaneous targets, add min/max bounds, integer or binary constraints, and optionally minimize or maximize an objective cell. Powered by HiGHS — an industrial-grade LP/MIP engine trusted by academics and professionals worldwide. Shortcut: ⌘⌥M (Mac) / Ctrl+Alt+M (Windows) ── SCENARIO MANAGER (Pro) ── Snapshot your model's inputs as named scenarios (Base Case, Bull Case, Bear Case). Restore any scenario instantly. Compare all scenarios side-by-side to see exactly how your outputs change across assumptions. ── SENSITIVITY ANALYSIS (Pro) ── • Tornado chart — rank your input cells by their leverage on the output • Data table — 2-variable heat map (a full what-if grid) • Monte Carlo — 1,000 simulations with P10 / P50 / P90 outcome ranges ── HOW IT WORKS ── • Right-click any formula cell → Goal Seek or Multi-variable Solve • Use keyboard shortcuts: ⌘⌥G or ⌘⌥M • Click the SolveSheet toolbar on the right edge of your sheet • Click the extension icon for quick access to all panels ── PRIVACY ── All computation runs in your browser. Your spreadsheet data never leaves your device and is never sent to any SolveSheet server.
