## Overview
Excel workbooks are a universal data interchange format — and a frequent source
of pain. This skill covers programmatic reading and writing of `.xlsx` files,
formula handling, styling for human-readable reports, and the patterns that keep
spreadsheet pipelines reliable at scale.
## When to use
- Generating formatted reports (styled headers, number formats, charts)
- Parsing uploaded spreadsheets with validation and error reporting
- Working with formulas: reading cached values vs recalculating
- Handling large workbooks without running out of memory (streaming)
- Migrating spreadsheet logic into code (or vice versa)
