The xlsx skill triggers whenever a spreadsheet is the primary input or output — adding columns, computing formulas, charting, cleaning messy tabular data, or converting between tabular formats. It uses openpyxl for formula-aware editing and pandas for analysis, with a mandatory recalc step to keep computed values correct.
