- High-performance CSV processing with xan CLI for large tabular datasets, streaming transformations, and low-memory pipelines.
xan
Use this skill when tabular work involves large CSV-like files and shell-oriented data 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.
Boundaries
- Not for workbook semantics (
.xlsxformula/layout preservation) — usexlsxorexcel-analysis. - Not for ML model training pipelines — use
data-mlskills. - This skill is a thin CLI wrapper; it does not implement custom parsing logic itself.
Script
- Path:
scripts/xan.ps1
Examples
powershell -ExecutionPolicy Bypass -File "$env:USERPROFILE\.codex\skills\xan\scripts\xan.ps1" count data.csv
powershell -ExecutionPolicy Bypass -File "$env:USERPROFILE\.codex\skills\xan\scripts\xan.ps1" filter "score > 0.8" data.csv
powershell -ExecutionPolicy Bypass -File "$env:USERPROFILE\.codex\skills\xan\scripts\xan.ps1" groupby category "sum(amount) as total" sales.csv
