+ UPI Transaction Analyzer 
 
-1. FinTech
+This Java application reads a UPI transaction CSV file and categorizes each transaction based on predefined keywords. It calculates category-wise spending, compares it to preset budget limits, and provides insightful summaries such as top overspent categories and weekly spending patterns.

+TransactionAnalyzer/ │ ├── ex.java # Main Java class to read and analyze UPI transactions ├── UPI_pay2.csv # Sample CSV file with UPI transaction data └── README.md # Project documentation
+---
+
+ How It Works
+
+1. *Input:* Reads from a .csv file with UPI transactions.
+2. *Categorization:* Matches transaction tags/remarks with keywords to determine category.
+3. *Spending Summary:*
+   - Outputs a table of transactions with category labels.
+   - Computes total spent per category.
+   - Checks against budget and shows overspent areas.
+4. *Weekly Analysis:*
+   - Groups transactions by week.
+   - Identifies the week with the highest spending.
+   - Breaks down spending by category for that week.
+
+
+
+ CSV Format
+
+Ensure your CSV file (UPI_pay2.csv) follows this format:
+Date,Time,Details,Amount,UPI,Remarks,Tags 01/04/2024,12:30 PM,Coffee Shop,-50,abc@upi,evening coffee,coffee cafe ...
