officecli-financial-model

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.

Financial Model Skill

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.

BEFORE YOU START (CRITICAL)

Every time before using officecli, run this check:

if ! command -v officecli &> /dev/null; then
    echo "Installing officecli..."
    curl -fsSL https://raw.githubusercontent.com/iOfficeAI/OfficeCli/main/install.sh -o /tmp/officecli_install.sh && bash /tmp/officecli_install.sh && rm -f /tmp/officecli_install.sh
    # Windows: irm https://raw.githubusercontent.com/iOfficeAI/OfficeCli/main/install.ps1 -OutFile "$env:TEMP\officecli_install.ps1"; & "$env:TEMP\officecli_install.ps1"
else
    CURRENT=$(officecli --version 2>&1 | grep -oE '[0-9]+\.[0-9]+\.[0-9]+' | head -1)
    LATEST=$(curl -fsSL https://api.github.com/repos/iOfficeAI/OfficeCLI/releases/latest | grep '"tag_name"' | sed -E 's/.*"v?([0-9.]+)".*/\1/')
    if [ "$CURRENT" != "$LATEST" ]; then
        echo "Upgrading officecli $CURRENT -> $LATEST..."
        curl -fsSL https://raw.githubusercontent.com/iOfficeAI/OfficeCli/main/install.sh -o /tmp/officecli_install.sh && bash /tmp/officecli_install.sh && rm -f /tmp/officecli_install.sh
    else
        echo "officecli $CURRENT is up to date"
    fi
fi
officecli --version

Use When

• User provides assumptions and asks for financial projections or a financial model
• User asks for an "income statement", "balance sheet", or "cash flow statement"
• User asks for DCF valuation, WACC calculation, or discounted cash flow analysis
• User asks for a cap table, waterfall analysis, or fundraising model
• User asks for scenario analysis, sensitivity table, debt schedule, or break-even model

Do NOT Use When

User Request	Correct Skill
CSV data to dashboard / charts	officecli-data-dashboard
Edit/modify an existing .xlsx	officecli-xlsx (editing.md)
KPI dashboard or metrics summary	officecli-data-dashboard
1-2 sheet visualization from existing data	officecli-data-dashboard
Word document or PowerPoint	officecli-docx / officecli-pitch-deck

What This Skill Produces

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.

---

Core Concepts

• Assumptions-First Architecture -- ALL hardcoded inputs go on the Assumptions sheet. Every other sheet references Assumptions. Changing one assumption recalculates the entire model.
• Financial Color Coding -- font.color=0000FF (blue) for inputs, font.color=000000 (black) for formulas, font.color=008000 (green) for cross-sheet references. Non-negotiable convention.
• Formula Chain Integrity -- Every derived value traces back to the Assumptions sheet through an unbroken chain of formula references.
• Error Checking -- Balance checks (Assets = Liabilities + Equity), cash reconciliation (CF ending cash = BS cash), and ISERROR scans on every sheet.
• Batch-First Workflow -- Use heredoc batch for ALL multi-cell operations, especially cross-sheet formulas. Verify after each batch.

---

Workflow Overview

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).

Quick Reference: Key Warnings

Warning	Detail
Cross-sheet ! escaping	Use heredoc batch for ALL cross-sheet formulas. Verify with officecli get after each batch.
Batch size limit	8-12 operations per batch, non-resident mode. Larger batches have ~33% failure rate.
Batch JSON values	ALL values must be strings: "true" not true, "24" not 24
fullCalcOnLoad + iterate	MANDATORY. Always use //x:definedNames --action insertafter (financial models always have named ranges)
Blue inputs / black formulas	font.color=0000FF on Assumptions inputs, font.color=000000 on all formula cells
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.
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 and calcPr MUST be the absolute last commands
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.

---

Known Issues

Issue	Workaround
! escaping in cross-sheet formulas	Always use heredoc batch. Verify with officecli get.
Batch failure at scale	Keep batches to 8-12 ops. Non-resident mode. Retry individually on failure.
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.
