Crunchy Sheets is an AI financial analyst that lives inside your Google Sheets™ sidebar. It understands your workbook the way a controller would — formulas, cross-tab references, named ranges, structural logic — and shows its work like one too. Ask it anything: "What's driving the variance in Q4?" "Build a 13-week cash flow forecast." "Explain what this formula does." "Pull my P&L from QuickBooks." "Prove that answer." It references your actual data and writes live formulas — not pasted numbers. Every proposed change is previewed in the sidebar before it touches your spreadsheet. Review, cherry-pick, or apply all. After applying, Crunchy Sheets re-checks its own output: error cells, hardcoded numbers where formulas belong, tie-outs that don't reconcile. The Proof tab. Ask "prove it" and Crunchy Sheets builds a workpaper tracing every number to its source cells, with a CHECK row that has to tie out. It's how analysts earn trust — showing the work so a reviewer can verify it end to end. Formula X-Ray. Inherited a model nobody dares touch? /xray traces any formula through its dependency chain and explains it in plain English. QuickBooks Online (Intuit's cloud accounting software). Pull P&L, balance sheet, and transaction reports straight into the sheet — no export, no copy-paste. Connecting requires a QuickBooks Online account. 15 built-in skills for finance work: variance analysis, budget vs actual, cash flow forecasting, scenario modeling, unit economics, cohort analysis, KPI dashboards, expense categorization, investor metrics, workbook formatting (blue inputs, black formulas), tab audits, and more. Plus custom commands you define yourself — a formatting pass, a sweep for review flags, whatever you'd otherwise do by hand. Built for month-end close, FP&A, and anyone who has to stand behind their numbers — controllers, fractional CFOs, startup finance teams, founders running finance lean. Built by a CPA who spent years building financial models by hand. Free to start: $6 of analysis credit — enough for a real evaluation, including Prove It — then a small monthly allowance. Paid plans from $20/month, renewing monthly until canceled — cancel anytime from the in-app billing portal. Crunchy Sheets can only access the spreadsheet you have open — never your Google Drive™ files or your email. Google Sheets™ and Google Drive™ are trademarks of Google LLC.
