Excel Export Validator - Customer Feedback Analyzer

Critical Requirements

Zero Errors Mandate

Every Excel export MUST be delivered with:

• ZERO formula errors (even though v3.9.0 uses static values)
• ZERO missing sheets
• ZERO column schema violations
• ZERO formatting errors

This is customer-facing output - quality is non-negotiable.

Project-Specific Validation Rules
