Data Import and Profiling

关于

Serves as a prerequisite for data analysis workflows by providing a structured five-phase approach to CSV ingestion. It handles everything from initial file discovery and encoding detection to complex schema design, standardization of inconsistent formats, and automated quality reporting. By utilizing specialized sub-agents for quality assessment and foreign key detection, this skill ensures data integrity is maintained and documented before any cleaning or analysis begins, making it ideal for robust data engineering tasks within the DataPeeker ecosystem.
