Set Up a Clean, Auditable Excel Workspace

This video covers the following learning objectives:

• Workbook Structure

  • Create modular sheets: Inputs, Calculations, Financials, Outputs, Audit

  • Use clear, consistent sheet naming conventions

• Formatting for Clarity and Auditability

  • Apply color conventions (e.g., blue for inputs, black for formulas)

  • Use bolding and fills to signal hierarchy and editable zones

• Navigation and Transparency

  • Build a Cover Sheet with metadata and links

  • Use Freeze Panes and formula auditing tools

• Input Block Design

  • Separate input blocks from calculations

  • Use consistent decimal formatting and clear labelling

• Documentation

  • Include a legend and notes section for versioning, units, and author info

• Model Governance

  • Avoid hardcoding, merged cells, and poor documentation

  • Save work in versions and audit logic with traceable outputs

• Final Checklist for Audit-Ready Models

  • Can outputs be traced to inputs?

  • Are inputs grouped, labeled, and editable?

  • Is the model usable by another analyst?
