Process tabular datasets with repeatable cleaning, schema checks, type normalization, and quality reporting. Use when transforming CSV/TSV exports, preparing analytics-ready data, validating required columns, or building deterministic ETL-style scripts.
Process files in bulk with deterministic naming, format conversion, filtering, and safe write patterns. Use when renaming large file sets, generating transformed copies, organizing directories, or applying repeatable file-level operations.
Extract structured data from websites with robots awareness, request throttling, selector-based parsing, and reproducible output. Use when collecting data from public pages, monitoring page changes, or converting HTML content into JSON/CSV datasets.
