Provides a paste‑ready prompt that, given two months of expense data, generates a concise comparison table. The prompt instructs the LLM to calculate total spend per category for the current month, the previous month, compute delta percentages, and highlight the top three increases. Input: two CSV snippets – one for the current month and one for the prior month – each with columns Date, Category, Amount. Output: a markdown table listing Category, Current Total, Prior Total, Δ%, and a brief insight sentence for each highlighted category.

- **Skipped row:** Date 2025-01-28, Category Miscellaneous, raw Amount “abc”
- **Category merge:** “dining” + “Dining” → unified as “Dining”
- **Currency assumption:** No currency symbol was present on all rows; the predominant symbol ($) was applied uniformly.
- **Missing dataset:** Prior month CSV was not provided; prior totals defaulted to $0.00 for all categories.
