XLIDE: VBA for VS Code
▶ Click the video above for the install tutorial
XLIDE gives Excel VBA projects a modern VS Code workspace.
Add one or more .xlsm, .xlsb, or .xlam workbooks to your VS Code project
and XLIDE detects them automatically. Navigate each workbook's VBA project in
the XLIDE tree, open modules directly from the workbook, edit with
workbook-aware IntelliSense, and save changes back to the workbook with normal
VS Code save behavior. When you want a file-based workflow, use the full local
disk push/pull workflow for the selected workbook: preview detailed
side-by-side diffs, export workbook modules to .bas and .cls files, commit
them to your favorite version control platform, and import reviewed files back
into that workbook.
For new programmers, XLIDE makes the VBA language easier to approach.
It shows useful completion lists, explains symbols, highlights likely mistakes,
and keeps the workbook's project structure visible while you learn how Excel
automation fits together.
For experienced VBA developers, XLIDE brings serious engineering workflows to
existing workbooks: project-wide symbol navigation, rename and reference tools,
full static analysis, live diagnostics, workbook-level analysis reports,
module-qualified IntelliSense, import/export diff previews, source-control
friendly .bas/.cls sync, explicit workbook settings, performance
diagnostics, and workbook unit tests that can execute through Excel when you
need runtime confidence.
For everyone, XLIDE opens a new agentic AI surface for Excel. Compatible AI
assistants can inspect the real workbook, read and write VBA modules, analyze
code, run tests, inspect worksheet data, and sync modules with files through
explicit XLIDE tools. That means AI help can work with the workbook itself, not
just copied snippets or stale exports, making Excel automation more reviewable,
testable, and collaborative.

Why Use XLIDE
Make VBA easier to learn and maintain
VBA is powerful, but its rules, project structure, and Excel object model can
feel hidden. XLIDE makes them visible with workbook navigation,
IntelliSense, hover explanations, signature help, semantic coloring, and
immediate feedback while you type.
Catch VBA mistakes earlier
XLIDE shows live red and yellow squiggles for many high-confidence VBA
problems: missing block closers, duplicate names, undeclared variables,
invalid parameter/property shapes, array misuse, bad Set usage, common
#If pitfalls, and more.
Get IntelliSense that understands your workbook
Completion and tooltips know about your modules, classes, functions,
constants, enums, user-defined types, XML documentation comments, and a broad
set of Excel object-model members.
Edit workbook VBA in a real code editor
Work with workbook modules in VS Code using normal editor habits: tabs,
search, save, rename, Go to Definition, Find All References, hover,
signature help, formatting-friendly indentation, and semantic coloring.
Keep workbook code reviewable
Export modules to .bas and .cls files, preview exactly what will change,
and use source control workflows without guessing what is inside a binary
workbook.
Import and export safely
XLIDE previews create, update, overwrite, and delete actions before applying
them. Workbook-specific settings live beside the workbook so each project can
keep its own sync rules.
Analyze the whole workbook
Run workbook-wide analysis and review findings in a dedicated report instead
of hunting through modules one by one.
Run macros and workbook tests when Excel is available
On Windows with Microsoft Excel installed, XLIDE can run macros and
@xlide-test workbook tests through explicit Excel automation.
Give AI assistants real workbook context
XLIDE exposes tools for workbook discovery, VBA reads/writes, analysis,
tests, sheet/cell access, formulas, and module sync so agents can work from
the actual workbook instead of stale exported files.
Who It Is For
XLIDE is useful if you:
- Are learning VBA for a class, internship, first automation project, or career
change.
- Use Excel heavily and want to start programming without losing sight of the
workbook.
- Are a student, analyst, accountant, engineer, researcher, or operations user
turning repeated spreadsheet work into reusable automation.
- Own business-critical Excel workbooks with VBA.
- Maintain shared macros for finance, operations, reporting, engineering, or
internal tools.
- Want better visibility into old VBA projects before changing them.
- Need to review workbook code with teammates.
- Prefer VS Code editing, search, navigation, and source control.
- Want AI help that can inspect the workbook directly.
Excel remains where the workbook runs. XLIDE adds a better workspace around the
VBA project.
Get Started
Install the extension:
XLIDE on the Visual Studio Marketplace
Install Python 3.10 or newer if you do not already have it:
Download Python
Open a folder in VS Code that contains an .xlsm, .xlsb, or .xlam
workbook.
Open the XLIDE view in the Activity Bar. If setup is incomplete, use the
sidebar buttons to choose Python and install the required Python libraries.
Expand your workbook, open a module, and start editing. Press Ctrl+S to
save code back to the workbook.

Getting started with XLIDE
Everyday Workflow
Edit VBA modules
Open a workbook in the XLIDE tree, choose a module, edit it in VS Code, and save.
XLIDE writes the module back to the workbook.
Fix red squiggles
Live diagnostics appear as you type. For a bigger pass, run XLIDE: Analyze
Workbook from the workbook menu and review the analysis report.
Guide:
Analysis and ignores
Sync code with files
Use Export Modules to Folder to create or update .bas and .cls files.
Use Import Modules from Folder to bring reviewed files back into the
selected workbook. XLIDE shows a workbook-scoped preview before applying
changes.
Guide:
Import and export
Run tests
Mark VBA procedures as workbook tests, then run them from XLIDE. Test execution
requires Microsoft Excel on Windows.

Testing VBA workbooks
Use AI assistants safely
XLIDE gives compatible VS Code AI agents tools to inspect and edit workbook VBA,
run analysis, export modules, and read worksheet data with explicit workbook
context.

Requirements
Required for normal browsing, editing, analysis, import, and export:
- Visual Studio Code 1.95 or newer.
- Python 3.10 or newer.
- Python packages installed by XLIDE setup:
pyOpenVBA and openpyxl.
Required only for running VBA code from XLIDE:
- Windows.
- Microsoft Excel.
- Workbook macro settings that allow the code to run.
Reading, editing, analyzing, importing, and exporting workbook VBA do not require
Excel automation.

Notes And Limits
- XLIDE reads and writes VBA modules through the workbook file. Keep normal
backups for important workbooks, especially before large sync operations.
- Running macros or tests uses Excel automation and is Windows-only.
- UserForm designer files are not edited directly. XLIDE can work with the VBA
code-behind where supported.
- Live Share guests can view and edit modules the host has already opened, but
only the host can browse the XLIDE workbook tree.
- Exported
.bas and .cls files are useful for review and source control, but
the workbook remains the source of truth unless you explicitly import files
back into it.
