Agent Metadata
Known Gotchas
- ⚠ Excel files must exist locally — agents cannot create files from scratch without a template or create path
- ⚠ Large Excel files (100K+ rows) can be slow to process — openpyxl loads entire file into memory
- ⚠ Formulas are stored as text by openpyxl — calculated values require Excel or xlcalculator
- ⚠ Not compatible with older .xls format — only .xlsx supported
