High-performance CSV processing with xan CLI for large tabular datasets, streaming transformations, and low-memory pipelines.

When to use

• CSV/TSV files are large (size or rows) and Python/pandas style processing is too heavy.
• You need fast CLI operations such as `filter`, `sort`, `dedup`, `groupby`, `frequency`, `join`.
• You want low-memory streaming workflows in terminal pipelines.

When not to use

• workbook semantics
• .xlsx formula/layout preservation
• ML model training pipelines
• custom parsing logic
