Cloud & AI Options
Ce contenu n’est pas encore disponible dans votre langue.
Modern Excel ships with several cloud and AI features that can read your workbook and send its content to external servers. To keep your protected application sealed, XLS Padlock blocks all of them by default. You decide, one by one, which ones to allow.
You will find these settings in the XLS Padlock designer under the Security tab, on the Cloud & AI page.
Why these features are blocked by default
Section titled “Why these features are blocked by default”Each option on this page is a known way for workbook data to leave the end user’s machine. A protected workbook is meant to keep your formulas, data, and VBA code under your control, so XLS Padlock starts from the safest position: everything off. Turn on only what your customers genuinely need.
Available options
Section titled “Available options”All three options are unchecked (blocked) by default.
Allow Office JS web add-ins
Section titled “Allow Office JS web add-ins”Office JS web add-ins (also called web add-ins) run inside Excel and can read every cell of the open workbook and send that data to their own servers. This includes third-party add-ins such as the Claude for Excel plugin and any other JS add-in installed from the Office store or sideloaded.
When this option is off, web add-ins cannot load against your protected workbook. Enable it only if your application depends on a specific web add-in that you trust.
Allow Office Scripts and Power Automate
Section titled “Allow Office Scripts and Power Automate”Office Scripts (TypeScript automation scripts) and Power Automate flows can read workbook content and move it out of the application. Leave this off unless your workflow relies on them.
Allow Microsoft connected experiences
Section titled “Allow Microsoft connected experiences”Microsoft connected experiences send cell content to Microsoft cloud services. This covers Microsoft Copilot, Python in Excel, Smart Lookup, Editor, Translator, and Designer. Enable it only if your customers need these features and you accept that the relevant cell content may be processed in the Microsoft cloud.
- These options apply to the compiled application, not to the XLS Padlock designer.
- Blocking these surfaces also hides their entry points in the Excel ribbon (for example the Add-ins flyout, the Automate tab, and the Copilot button), so end users are not prompted to use a feature that is turned off.
- COM add-ins and the built-in Excel add-ins are managed separately. See How to Manage Excel Add-ins.
