Integration Best Practices
Excel Model Creation (CRITICAL)
When using xlsx skill to create CRE financial models:
- NO HARDCODING: Use formulas with cell references - never hardcode values in calculation cells
- Color Coding: Blue text = inputs, Black text = formulas, Green text = cross-sheet references
- Cell References: All calculations must reference Assumptions tab (e.g.,
=Assumptions!$B$5)
- Consistent Formulas: Copy formulas across periods - don't manually enter values
- Professional Formatting: Currency as
$#,##0, zeros as "-", negatives as (123)
- Zero Errors: Deliver models with NO #REF!, #DIV/0!, #VALUE!, or #N/A errors
- Documentation: Source all blue assumption inputs in adjacent cells or comments
Example of CORRECT formula structure:
❌ WRONG: =1450 * 180 * 12 * 1.03
✅ CORRECT: =Assumptions!$B$8 * Assumptions!$B$5 * 12 * (1 + Assumptions!$B$9)
Data Extraction Priority
- Always extract and validate source data before creating analysis
- Cross-reference multiple documents when available (e.g., rent roll vs. offering memo)
- Flag discrepancies between documents
- Document all data sources in final output
Quality Control
- Verify extracted numbers match source documents
- Check for data entry errors or OCR mistakes (especially with PDFs)
- Validate calculations independently
- Compare extracted assumptions to market standards
- Excel Models: Test that changing any assumption flows through entire model
Common Document Combinations
- Acquisition package: Offering memo (PDF) + T-12 (Excel) + Rent roll (Excel) + Photos
- Due diligence: Appraisal (PDF) + PCA (PDF) + Phase I Environmental (PDF) + Title report (PDF)
- Underwriting: Financial model (Excel) + Market study (Word/PDF) + Comp set (Excel)
- Investment committee: Analysis memo (Word) + Financial model (Excel) + Presentation (PowerPoint)
Handling Common Document Issues
Scanned PDFs (Non-searchable)
- The
pdf skill includes OCR capabilities for scanned documents
- May require additional processing time
- Verify extracted data accuracy due to OCR errors
Protected/Encrypted PDFs
- The
pdf skill can handle password-protected files if password is provided
- Some restrictions may prevent text extraction
Complex Excel Models
- Focus on extracting key inputs and outputs
- Validate formulas when possible
- Note assumptions and limitations
Legacy File Formats
.doc files: Convert to .docx before processing.xls files: Usually can be read by xlsx skill- Older formats may require conversion
