🏷️ Labels: Python, Data Transformation, Finance, Pandas, Data Pipeline
📂 Project: Dev
⭐ Priority: MEDIUM
Session Goal
The goal of this session was to develop a Python pipeline capable of transforming Wise-style transaction data into a standardized ledger format for financial analysis.
Key Activities
- Data Manipulation: Added missing transaction rows to a pandas DataFrame using a list of dictionaries.
- DataFrame Generation: Created a DataFrame from extra Wise transactions, adding unique IDs for each entry.
- Ledger Entry Formatting: Provided missing ledger entries formatted to match existing transactions.
- Pipeline Development: Developed a Python pipeline to read, parse, and transform Wise-style transaction datasets into a canonical ledger format.
- Data Aggregation: Outlined steps for monthly aggregation of financial transactions, including calculations for net monthly flow and visual summaries.
- Data Accuracy Considerations: Addressed potential issues such as date format inconsistencies and currency misalignment before data aggregation.
- Troubleshooting: Identified and resolved file reading issues in directories, ensuring proper file management.
Achievements
- Successfully developed a comprehensive Python pipeline for transforming and aggregating Wise transaction data.
- Enhanced data accuracy and processing efficiency through detailed troubleshooting and data manipulation techniques.
Pending Tasks
- Review and refine the data aggregation function to ensure accuracy in monthly financial summaries.
- Implement additional error handling mechanisms in the pipeline to address potential data inconsistencies.
