Table Structures & Column Definitions (Expense Log)

The main data collection table is located on the "Expense Log" sheet and contains the following columns with defined data types:

Formulas Required for Data Integrity & Automation

• Data Validation: Use Excel’s Data Validation feature to restrict Category and Subcategory entries to predefined lists from the "Categories & Subcategories" sheet.
• Dynamic Dropdowns: Implement INDIRECT() and named ranges for cascading dropdowns (Category → Subcategory).
• Date Range Filtering: Use FILTER() function in Excel 365 to dynamically display only relevant data based on user-selected date range.
• Running Totals: In the "Monthly Summary" sheet, use SUMIFS() with criteria like Date (year-month), Category, and Subcategory to aggregate monthly totals.
• Recurring Expense Detection: Apply conditional logic using IF and COUNTIF to flag expenses that occur on similar dates across multiple months.
• Auto-Calculate Average Spend: Use AVERAGEIFS() to compute average spend per category over the last 3, 6, or 12 months.

Conditional Formatting Rules

• Critical Expense Alert: Highlight any transaction with Amount > $500 in red text and yellow background to flag high-value items.
• Budget Thresholds: Apply color scales (red-yellow-green) for monthly category totals that exceed, meet, or are under budget targets.
• Pending Payments: Use conditional formatting on the "Status" column to show "Pending" entries in orange for urgent follow-up.
• Trend Visualization: Apply data bars within cells of monthly totals to show volume comparison at a glance.
