Csv Processor

This handles the everyday CSV grunt work you'd normally reach for pandas or csv-parser to do. It'll auto-detect delimiters and encodings, filter rows with conditions like "age > 30", merge multiple files, remove duplicates, and generate basic stats. The skill covers both Python and JavaScript implementations with actual code patterns for reading, writing, filtering, sorting, and grouping data. Honestly most useful when you're doing quick data cleanup or analysis and don't want to write boilerplate parsing code. The pivot table and aggregation examples are solid if you're doing anything beyond basic row filtering.
