概要
The xlsx skill enables Claude to perform sophisticated spreadsheet operations, moving beyond static data exports to create fully functional, dynamic Excel models. It supports complex formula injection, professional financial formatting conventions (such as color-coded inputs and calculations), and automated error validation. By leveraging pandas for data manipulation and openpyxl for formatting preservation, it ensures spreadsheets remain professional and updateable. The skill includes a mandatory recalculation engine that uses LibreOffice to verify that every model is delivered with zero formula errors, making it an essential tool for analysts and developers alike.
