Use this skill when the user wants to build a financial model, 3-statement model, DCF valuation, cap table, scenario analysis, or financial projections in Excel. Trigger on: 'financial model', '3-statement model', 'DCF', 'cap table', 'pro forma', 'projections', 'sensitivity analysis', 'waterfall', 'debt schedule', 'break-even', 'discounted cash flow', 'capitalization table', 'fundraising model', 'WACC calculation', 'scenario analysis model'. Input is a text prompt with assumptions. Output is a single .xlsx file with formula-driven, interconnected statement sheets.
Build formula-driven, multi-sheet financial models from scratch in Excel. Every number on every statement sheet is a formula referencing the Assumptions sheet. Output is a single .xlsx file with interconnected sheets -- Income Statement, Balance Sheet, Cash Flow Statement, and optional valuation or scenario analysis sheets.

A single .xlsx file with 4-10 interconnected sheets:
| Sheet Type | Purpose | Key Characteristic |
|---|---|---|
| Assumptions | All hardcoded inputs in one place | Blue font (0000FF) on every input cell |
| Income Statement | Revenue through Net Income | All rows are formulas referencing Assumptions |
| Balance Sheet | Assets, Liabilities, Equity | Must balance every period; includes check row |
| Cash Flow Statement | Operating, Investing, Financing | Ending Cash must equal BS Cash |
| DCF / Valuation | WACC, FCF, Terminal Value, Equity Value | Named ranges for key inputs |
| Sensitivity Table | 2-variable grid of implied values | Each cell is a self-contained formula |
| Scenarios | Dropdown-driven Base/Bull/Bear | IF/INDEX formulas reference dropdown |
| Error Checks | Balance, cash reconciliation, ISERROR scan | "ALL CLEAR" or "ERRORS FOUND" summary |
| Dashboard / Charts | Visual summary of model outputs | Charts use cell range references |
ALL values on statement sheets are formulas. The only hardcoded numbers are on the Assumptions sheet.
font.color=0000FF (blue) for inputs, font.color=000000 (black) for formulas, font.color=008000 (green) for cross-sheet references. Non-negotiable convention.Phase 1: Understand -- Identify model type (3-statement, DCF, cap table, scenario). Determine which sheets are needed and the formula dependency chain.
Phase 2: Plan -- Map sheet structure, column layout (labels + year columns), and cross-sheet formula dependencies. Define the build order.
Phase 3: Build -- Follow the mandatory 10-step build sequence in creating.md Section A.7. Build in layers: structure, assumptions, formulas (IS then BS then CF), formatting, charts, protection, raw-set, validate.
Phase 4: QA -- Run the QA checklist: validate, formula error scan, cross-sheet verification, balance check, cash reconciliation, chart data check.
Phase 5: Deliver -- Deliver the .xlsx file. Note that formulas recalculate on open (fullCalcOnLoad is set).
| Warning | Detail |
|---|---|
| Sheet names with spaces in CLI paths (REQUIRED) | When using officecli get or officecli set with a sheet name that contains spaces (e.g., "Cash Flow", "ARR Waterfall"), the sheet name portion of the path MUST be wrapped in single quotes: officecli get model.xlsx "'/Cash Flow/A1'". Without single quotes, the command fails with Err:509. In JSON batch paths, no extra quoting is needed (the JSON string already handles it). |
Cross-sheet ! escaping | Use heredoc batch for ALL cross-sheet formulas. Verify with officecli get after each batch. |
| Batch size limit | 15-20 ops per batch in resident mode (recommended). 8-12 ops without resident mode. |
| Batch JSON values | ALL values must be strings: "true" not true, "24" not 24 |
| fullCalcOnLoad + iterate | MANDATORY. Use officecli set model.xlsx / --prop calc.fullCalcOnLoad=true --prop calc.iterate=true. Do NOT use raw-set (creates duplicates). |
| Blue inputs / black formulas | font.color=0000FF on Assumptions inputs, font.color=000000 on all formula cells |
| Header row background color (REQUIRED) | All section header rows MUST have fill set. Use "fill":"1F3864","font.color":"FFFFFF" (dark navy + white text). Header rows without fill fail the Quality Bar check (Q2). |
| Header row fill MUST cover ALL columns (A:D or A:G) | Section header rows (REVENUE, ASSETS, etc.) must apply the dark fill to ALL columns in that row, not just the A-column label cell. If only A is filled, B/C/D columns on that row show black text on a white background — extremely poor readability against the dark header. Correct: {"command":"set","path":"/P&L/A5:D5","props":{"shd":"1F3864","color":"FFFFFF","bold":true}}. Wrong: set only /P&L/A5. |
| Balance sheet must balance | Explicit check formula: =TotalAssets - TotalLiabilities - TotalEquity must equal 0 |
| Cash reconciliation | CF ending cash must equal BS cash for every period |
| No Excel Data Tables | Sensitivity tables must be manual formula grids. Each cell is an explicit self-contained formula. |
Before delivering the .xlsx file, verify all items:
| # | Check | How to Verify |
|---|---|---|
| 1 | Freeze panes on every data sheet | officecli get model.xlsx "/Sheet" — confirm freeze property is set |
| 2 | Formula cells have black font (000000) | No CLI command can reliably detect font color. officecli view text does NOT output font color information — any grep-based check against color values is a false negative and always returns 0 lines regardless of actual color. Must verify visually: run officecli view model.xlsx html > preview.html and open in browser, or take a screenshot, and confirm formula cells appear in black. Apply Step 8f to ALL sheets before verifying. |
| 3 | Input cells have blue font (0000FF) | Assumptions sheet cells B:D must be blue |
| 4 | Header rows fill covers ALL columns (A:D or wider) | Screenshot check — no white-background cells in header rows |
| 5 | Balance Check = TRUE every period | officecli get model.xlsx "/Balance Sheet/B18" --json |
| 6 | Cash Reconciliation = TRUE every period | officecli get model.xlsx "/Cash Flow/B21" --json |
| 7 | No \! in cross-sheet formulas | officecli get model.xlsx "/Income Statement/B3" — no backslash |
| 8 | fullCalcOnLoad + iterate set | officecli validate model.xlsx passes |
| 9 | Year 2+ Beginning ARR = Prior Year Ending ARR | No independent "Opening ARR" input in Assumptions for Year 2+ |
| 10 | Opening Equity = Opening Assets - Opening Liabilities | Balance Check Year 1 = TRUE (not hardcoded equity value) |
| Issue | Workaround |
|---|---|
! escaping in cross-sheet formulas | Always use heredoc batch. Verify with officecli get. |
| Batch failure at scale | Use resident mode + 15-20 ops per batch. If failure persists, reduce to 8-12. Retry individually as last resort. |
| Cannot rename sheets | Plan sheet names upfront before creation. |
| Sensitivity tables are manual | Each cell needs an explicit formula. No Excel DATA TABLE support. |
| Chart series fixed at creation | Cannot add series later. Plan all series before add. |
| Formula cached values blank | view text shows blank for formula cells. This is normal. Set fullCalcOnLoad. |
| Waterfall chart totals | Cannot mark bars as totals programmatically. Use color convention. |
| Circular references | Use <calcPr iterate="1" ...>. Design model to avoid unnecessary circularity. |
Chart title $ stripping | Shell expands $ in --prop title. Use heredoc batch for chart titles with $, or omit $ from titles. |
| AP formula sign error | AP (Accounts Payable) must be a positive number. If COGS is stored as a negative value, AP formula must negate it: =-COGS*DPO/365. Wrong sign causes NWC overstatement and incorrect Cash Flow direction. See creating.md C.6 WARNING. |
#NAME? not detectable by query/validate | officecli query and validate cannot detect runtime #NAME? errors from unquoted sheet names (e.g., P&L!B3). Run screenshot check (creating.md E.8 Step 10) when any sheet name contains &, spaces, or parentheses. |
When the user requests changes after the model is built:
| Request | Command |
|---|---|
| Swap two sheets | officecli swap model.xlsx '/Sheet1' '/Sheet2' |
| Move a sheet after another | officecli move model.xlsx '/Scenarios' --after '/Assumptions' |
| Edit a cell value | officecli set model.xlsx '/SheetName/A1' --prop value="..." |
| Find & replace text | officecli set model.xlsx / --prop find=OldText --prop replace=NewText |
| Remove a row | officecli remove model.xlsx '/SheetName/row[N]' |
Read creating.md and follow it step by step. It contains setup conventions, core financial statement patterns, advanced patterns (DCF, sensitivity, scenarios), chart recipes, QA checklist, and known issues with workarounds.
Number format $ quoting |
Use heredoc batch or single quotes to prevent shell expansion of $ |
| Named ranges required | Define for all key assumptions (WACC, growth rates, tax rate). Required for auditability. |
| Column widths | No auto-fit. Set explicitly: labels=22-28, numbers=14-18, year headers=12-14 |
| formulacf no font.bold | Use fill + font.color only. font.bold causes validation errors. |
| raw-set ordering | activeTab raw-set MUST be the last command. calcPr uses high-level set / --prop calc.* instead of raw-set. |
| BS Cash = CF Ending Cash | BS Cash ALWAYS equals =Cash Flow!B19, including Year 1. Never use cash-as-plug or reference Assumptions directly. |
Chart title $ in shell | Use heredoc batch for chart titles containing $ to prevent shell expansion. |
| Freeze panes (REQUIRED on every data sheet) | Every sheet with column headers must have freeze panes set (freeze=B2 or freeze=B3). Missing freeze panes is a Hard Rule violation. Apply in Step 8e of build sequence. |
| Formula cells black font (REQUIRED) | All formula cells on statement sheets must have font.color=000000. Omitting this makes the Blue=Input / Black=Formula color convention invisible. Apply in Step 8f of build sequence. Step 8f applies to EVERY formula cell on EVERY statement sheet — Income Statement, Balance Sheet, Cash Flow, Assumptions (roll-forward/output rows), and all auxiliary sheets. Apply by row range for each sheet; do NOT apply to only one sheet or one section. |
| H8: Summary or Dashboard sheet (REQUIRED) | Every financial model output MUST include a Summary or Dashboard sheet containing at least 4 KPI values sourced from the statement sheets (e.g., Revenue, EBITDA, Net Income, Ending Cash, or equivalent). A model delivered without a Summary/Dashboard sheet fails this Hard Rule. Specialized single-purpose models (ARR Waterfall, DCF-only) satisfy this with a dedicated Summary tab. Tab color: 70AD47 (green). |
