Use When

• Generate world-class, professionally designed Microsoft Excel spreadsheets and handle all Excel/spreadsheet workflows. Use when: generating .xlsx files from apps or scripts (openpyxl, xlsxwriter, PhpSpreadsheet, pandas), importing or parsing...
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to excel-spreadsheets or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve; load references only as needed.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
