🏷️ Labels: DBF, TXT, Data_Conversion, Python, Automation
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal

The session aimed to address and resolve issues related to the conversion of DBF files to TXT format and to improve the handling and classification of these files within the data processing pipeline.

Key Activities

• Identified and provided solutions for conversion errors due to unescaped characters and missing data for specific quarters.
• Enhanced the download_quarter() function to handle legacy files from 2003-2009, including filename normalization.
• Reviewed the fetch and extract process for DBF files, identifying file handling issues and suggesting improvements.
• Implemented filename-based routing in the download_quarter() function to ensure proper organization of legacy DBF files.
• Modified file processing code to be case-insensitive, ensuring consistent handling of DBF files with varying capitalization.
• Corrected classification issues for .txt files, ensuring they are moved to the correct subdirectories based on specific prefixes.

Achievements

• Successfully resolved conversion and classification issues, ensuring smooth data extraction and uniform naming conventions.
• Improved the automation and accuracy of file handling processes within the data pipeline.

Pending Tasks

• Further testing and validation of the implemented solutions to ensure robustness across different datasets and scenarios.
