 # Tree Planting Data Validator 🌳
 
-A lightweight Python script that validates tree planting records stored in Excel files. It reads the data, cleans trailing blank rows, counts records, and produces a clear validation report.
+**A robust Python script to validate Excel-based tree planting records.**
 
-Perfect for NGOs, reforestation projects, environmental organizations, or anyone managing large-scale tree planting data.
+This tool ensures that tree planting data submissions meet quality standards before being imported into databases or mapping systems. It performs comprehensive checks on participant types, planting dates, geographic coordinates, and tree sources.
 
-## Features
+---
 
-- Reads Excel files with customizable header row
+## ✨ Features
-- Automatically cleans trailing/empty rows
-- Reports total records processed
-- Extensible validation framework (ready for additional checks)
-- Command-line interface with useful options
-- Optional CSV error report export
 
-## Requirements
+- **Flexible column matching**: Automatically detects common column name variations
+- **Data cleaning**: Removes blank rows and normalizes input
+- **Comprehensive validation**:
+  - Required fields check
+  - Participant type validation
+  - Date range and format validation (no future dates, no pre-2024 planting)
+  - Geographic boundary validation (Northeast US focus)
+  - Tree source categorization
+- **Clear, human-readable error reports** grouped by Excel row
+- **Command-line interface** with optional CSV error export
+- **Debug mode** for troubleshooting
 
-- Python 3.8+
