"Transform plain or raw Excel reports into polished, presentation-ready workbooks with warm vivid color scales, conditional formatting, data bars, frozen panes, and annotated headers. Use this skill whenever the user uploads an .xlsx file and asks to make it 'colorful', 'impactful', 'presentation-ready', 'annotated', 'formatted', 'polished', or wants outliers to stand out. Also trigger when the user says 'add color scales', 'highlight outliers', 'make it pop', 'style this spreadsheet', 'beautify this Excel', or 'format for leadership'. Works on any multi-sheet Excel workbook. Does NOT create new analysis or change data -- only applies visual formatting on top of existing content."
