What is xlide_vscode?

XLIDE is a VS Code extension that lets you edit the VBA code inside Excel workbooks directly in VS Code, instead of using Excel's own built in VBA editor. VBA is the scripting language Excel uses for macros and automation. It shows all the VBA modules in a workbook in a sidebar tree, lets you edit them with proper syntax highlighting, jump to where something is defined, find everywhere something is used, and rename things safely across the whole project. Saving with Ctrl+S writes your changes straight back into the original .xlsm file. It also exposes every one of these actions as a tool that GitHub Copilot can call directly, so an AI coding assistant can read, list, and even write VBA modules and spreadsheet cells on your behalf, with a confirmation prompt required before it changes anything. Under the hood, a Python process running in the background handles the actual reading and writing of the Excel file, using two open source libraries: one that reads and writes VBA code directly from the file format, and another that reads and writes spreadsheet cells. Because of this approach, XLIDE does not need Excel or Windows specific automation installed, and works on Windows, macOS, Linux, and remote development containers. To use it, you need VS Code 1.95 or newer and Python 3.10 or newer, along with two Python packages that the setup installs for you. There is no need for Microsoft Office to be installed at all. Live Share collaboration has a limitation: only the person hosting the session can browse and open new VBA modules, since Microsoft restricts this kind of shared functionality to its own first party extensions. Guests can still edit any module the host already has open.
