## What it does

The skill pulls financial data from CIMs, offering memorandums, SEC filings, web search or MCP servers and lays it out in one workbook template. The structure is 8 tabs: Executive Summary, Income Statement, Balance Sheet, Cash Flow, Operating Metrics, Property/Segment Performance, Market Analysis, Investment Highlights.

Formatting rules are strict. Money metrics get currency format with `$`, operational counts stay plain numbers, percentages render as `0.0%`, and years are stored as text so Excel does not insert a comma. Every subtotal, total and ratio is a formula, never a hardcoded value. Font colour marks what a cell is: blue for hand-entered inputs, black for calculations, green for links to other sheets.

File creation and editing run through a separate `xlsx` skill. The balance sheet has to balance — assets equal liabilities plus equity — and cash flow must tie to balance sheet changes. Simple financial calculations and already-finished data packs are outside its scope.

## When to use it
- build an investment committee workbook from a CIM and filings
- standardize reporting across several portfolio companies
- apply the right number format to money and operational metrics
- check that the balance sheet balances and cash flow ties to it
- document assumptions with page references to source documents

## Example prompts
- Build a data pack from this CIM using the 8-tab structure
- Pull the financials from this SEC filing into Excel with formulas, not hardcoded values
- Standardize the reporting of three portfolio companies into one template

# Financial Data Pack Builder

Build professional, standardized financial data packs for private equity, investment banking, and asset management. Transform financial data from CIMs, offering memorandums, SEC filings, web search, or MCP server access into polished Excel workbooks ready for investment committee review.

**Important:** Use the xlsx skill for all Excel file creation and manipulation throughout this workflow.

## CRITICAL SUCCESS FACTORS

Every data pack must achieve these standards. Failure on any point makes the deliverable unusable.

### 1. Data Accuracy (Zero Tolerance for Errors)
- Trace every number to source document with page reference
- Use formula-based calculations exclusively (no hardcoded values)
- Cross-check subtotals and totals for internal consistency
- Verify balance sheet balances: Assets = Liabilities + Equity
- Confirm cash flow ties to balance sheet changes

### 2. ESSENTIAL RULES

**RULE 1: Financial data (measuring money) → Currency format with $**
Triggers: Revenue, Sales, Income, EBITDA, Profit, Loss, Cost, Expense, Cash, Debt, Assets, Liabilities, Equity, Capex
Format: $#,##0.0 for millions, $#,##0 for thousands
Negatives: $(123.0) NOT -$123

**RULE 2: Operational data (counting things) → Number format, NO $**
Triggers: Units, Stores, Locations, Employees, Customers, Square Feet, Properties, Headcount
Format: #,##0 with commas
Negatives: (123) consistent with rest of table

**RULE 3: Percentages (rates and ratios) → Percentage format**
Triggers: Margin, Growth, Rate, Percentage, Yield, Return, Utilization, Occupancy
Format: 0.0% for one decimal place
Display: 15.0% NOT 0.15

**RULE 4: Years → Text format to prevent comma insertion**
Format: Text or custom to prevent 2,024
Display: 2020, 2021, 2022, 2023A, 2024E
```
