What data formats does the analyzer support?

The analyzer can process data from Excel files (.xlsx), CSV files, or data tables pasted directly into the chat interface.

Does it provide explanations for the differences?

Yes, it generates automated commentary for flagged items, identifying potential business drivers like sales volume shifts, pricing pressure, or operational efficiencies.

Can I customize the materiality thresholds?

Yes, you can specify your own percentage thresholds (e.g., 5%) or absolute dollar amounts (e.g., $10k) when invoking the skill to control which items get flagged.

Can it analyze multiple periods at once?

If data for multiple months or quarters is provided, the skill automatically generates a Trend Analysis sheet to visualize performance shifts over time.

How does it handle revenue versus expense variances?

The skill uses correct financial sign conventions: positive variances for revenue/profit are flagged as favorable (Green), while positive variances for expenses are flagged as unfavorable (Red).
