xl

Write type-safe Scala scripts against the xl library (com.tjclp::xl, via scala-cli) for complex Excel/.xlsx work: bulk or conditional transformations, multi-file pipelines, typed data extraction into Scala types, formula-heavy model building, and streaming 100k+ row files. Prefer over the xl-cli skill when a task needs loops, intermediate computation, or many dependent edits that would round-trip the file repeatedly; use xl-cli for quick reads, single edits, and visual exports.

LLM-friendly Excel operations via the `xl` CLI. Read cells, view ranges, search, evaluate formulas, export (CSV/JSON/PNG/PDF), style cells, modify rows/columns. Use when working with .xlsx files or spreadsheet data.
