Data Transform Pipeline

Stop wrestling with data format conversions. This skill gives your agent a complete data transformation toolkit: convert between CSV, JSON, XML, and YAML with a single command. Filter rows by condition, aggregate columns (sum, avg, count, min, max), reshape nested structures, and validate schemas. Handles messy real-world data — missing fields, mixed types, encoding issues. All pure bash + jq + awk — works on any Unix system with zero setup. Perfect for ETL pipelines, report generation, API response processing, and data migration tasks.
