Here are a few highlights of xlwings Server: - Create modern Excel add-ins (“Office.js add-ins”)—no VBA involved - Supports Excel on Windows, Excel on macOS, and Excel on the web - Install any Python package, including your own - Write automation scripts and custom functions with Python instead of dealing with JavaScript, Node, and Webpack - Develop custom task pane applications using the web technology of your choice - Highest security: runs in air-gapped environments without internet access or connection to any Microsoft servers - Intellectual property protection: the Python source code can’t be accessed by the Excel user - Supports SSO (single sign-on) authentication and RBAC (role-based access control) via Microsoft Entra ID (previously known as Azure AD) - No sensitive credentials need to be stored on the end-user’s computer or in the workbook - Compatible with Python 3.11+
