XLIDE is an extension for editing Microsoft Office VBA projects within VS Code, available for installation from the Visual Studio Marketplace. When macro-enabled files (.xlsm, .docm, .pptm, .accdb, etc.) for Excel, Word, PowerPoint, and Access are added to a project, the extension automatically detects them and provides IntelliSense tailored to the host application's object model, static analysis, export to .bas / .cls, and version control integration.

The extension reportedly provides an "agentic AI surface" that allows compatible AI assistants to directly access actual files to perform reading/writing of VBA modules, code analysis, test execution, reference of worksheet data, and synchronization of modules with files via XLIDE-specific tools. The extension explains that because AI assistance can target the documents themselves rather than copied snippets or outdated exports, the reviewability, testability, and collaborativeness of Office automation are improved.
