Install and run

Setup complexity: low.

clawhub skill install s170bfqwae6mtf922jhz299q7s83jb0h:financial-modeling-qa-xlsx

Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# Requirements for Outputs

## All Excel files

### Zero Formula Errors
- Every Excel model MUST be delivered with ZERO formula errors (#REF!, #DIV/0!, #VALUE!, #N/A, #NAME?)

### Preserve Existing Templates (when updating templates)
- Study and EXACTLY match existing format, style, and conventions when modifying files
- Never impose standardized formatting on files with established patterns
- Existing template conventions ALWAYS override these guidelines

## Financial models

### Color Coding Standards
Unless otherwise stated by the user or existing template

#### Industry-Standard Color Conventions
- **Blue text (RGB: 0,0,255)**: Hardcoded inputs, and numbers users will change for scenarios
- **Black text (RGB: 0,0,0)**: ALL formulas and calculations
- **Green text (RGB: 0,128,0)**: Links pulling from other worksheets within same workbook
- **Red text (RGB: 255,0,0)**: External links to other files
- **Yellow background (RGB: 255,255,0)**: Key assumptions needing attention or cells that need to be updated

### Number Formatting Standards

#### Required Format Rules
- **Years**: Format as text strings (e.g., "2024" not "2,024")
- **Currency**: Use $#,##0 format; ALWAYS specify units in headers ("Revenue ($mm)")
- **Zeros**: Use number formatting to make all zeros "-", including percentages (e.g., "$#,##0;($#,##0);-")
- **Percentages**: Default to 0.0% format (one decimal)
- **Multiples**: Format as 0.0x for valuation multiples (EV/EBITDA, P/E)
- **Negative numbers**: Use parentheses (123) not minus -123

### Formula Construction Rules

#### Assumptions Placement
- Place ALL assumptions (growth rates, margins, multiples, etc.) in separate assumption cells
- Use cell references instead of hardcoded values in formulas
- Example: Use =B5*(1+$B$6) instead of =B5*1.05

#### Formula Error Prevention
- Verify all cell references are correct
- Check for off-by-one errors in ranges
- Ensure consistent formulas across all projection periods
- Test with edge cases (zero values, negative numbers)
- Verify no unintended circular references

#### Documentation Requirements for Hardcodes
- Comment or in cells beside (if end of table). Format: "Source: [System/Document], [Date], [Specific Reference], [URL if applicable]"
- Examples:
  - "Source: Company 10-K, FY2024, Page 45, Revenue Note, [SEC EDGAR URL]"
  - "Source: Company 10-Q, Q2 2025, Exhibit 99.1, [SEC EDGAR URL]"
  - "Source: Bloomberg Terminal, 8/15/2025, AAPL US Equity"

skill-card.md

## Description:

Provides guidance and helper tooling for creating, editing, analyzing, formatting, visualizing, and recalculating spreadsheet files such as .xlsx, .xlsm, .csv, and .tsv.

This skill is ready for commercial/non-commercial use.

## Publisher:

[wu-uk](https://clawhub.ai/user/wu-uk)

### License/Terms of Use:

Proprietary

## Use Case:

Developers and agents use this skill to build, inspect, modify, format, analyze, and recalculate spreadsheet workbooks while preserving formulas and existing workbook conventions.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: The recalculation workflow can persistently install or overwrite a LibreOffice macro in the user's profile.

Mitigation: Run the skill in a disposable user profile or sandbox, review the macro behavior before use, and avoid using it on a primary LibreOffice profile.

Risk: Spreadsheet creation, editing, and recalculation can change workbook structure, formulas, and calculated values.

Mitigation: Keep backups of important spreadsheets and review formula error reports before relying on the resulting workbook.

## Reference(s):


## Skill Output:

**Output Type(s):** [text, markdown, code, shell commands, configuration, guidance]

**Output Format:** [Markdown guidance with Python and shell examples; generated spreadsheet artifacts may be XLSX, XLSM, CSV, or TSV files.]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [The recalculation helper returns JSON error reports and may modify local spreadsheet files during formula recalculation.]

## Skill Version(s):

0.1.0 (source: ClawHub release metadata)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
