Admins also have control over who can share scripts with others and who can use scripts in Power Automate. Currently, Office Scripts can be off for an entire tenant, on for an entire tenant, or on for a group of users in a tenant. This lack of granularity makes it hard to isolate a single bad actor. This means the script has neither the tokens of the signed-in user nor are there any API capabilities for signing in to an external service, so they are unable to use existing tokens to make external calls on behalf of the user.Īdmins have three options for VBA macros: allow all macros on the tenant, allow no macros on the tenant, or allow only macros with signed certificates. Additionally, no JavaScript authentication tokens can be shared with scripts. Office Scripts only have access to the workbook, not the machine hosting the workbook. This gives them full access to your desktop. VBA macros have the same security clearance as Excel. They can also make calls to a limited set of web services. This gives consistent behavior and accessibility, regardless of the machine being used to run the script. Office Scripts use a universal runtime for JavaScript.
However, VBA has no convenient way to call out to the internet. VBA can interact with a user's desktop to connect with similar technologies, such as COM and OLE. The following table shows which features are supported by which platforms and products. Since Office Scripts are only available for Excel, that is the only host being discussed here. This article describes the main differences between VBA macros (as well as VBA in general) and Office Scripts. The fundamental difference is that VBA macros are developed for desktop solutions and Office Scripts are designed for secure, cross-platform, cloud-based solutions. Both frameworks are designed to empower people who may not consider themselves programmers to create small programs in Excel.
They both allow users to automate solutions through an easy-to-use action recorder and allow edits of those recordings. Office Scripts and VBA macros have a lot in common.
