Worked on the duckdb/community-extensions repository to enhance data reliability by developing a robust CSV generation script for the extension index. Focused on RFC-4180 compliance, the solution ensured that multi-line and quoted descriptions were correctly handled, preventing parsing errors in downstream queries. Used bash scripting and data processing techniques to flatten per-extension data into single-line records, with proper escaping for quotes. Addressed a critical bug in the documentation generation workflow, eliminating build failures and improving site reliability. The approach emphasized maintainability by adopting printf-based row construction, and included thorough validation and documentation to support accurate aggregation queries and future development.
