Visual Basic for Applications (VBA) is an implementation of Microsoft's event-driven programming language Visual Basic 6.0 (VB6) built into most desktop Microsoft Office applications.
This is a curated list of Libraries and Resources for both VBA and VB6.
Because of the nature of VBA, many libraries do not work on all Operating Systems, in all Office Applications or on all architectures(x64/x86), therefore we use symbology. Read more about this here.

Because of the nature of VBA, many libraries do not work on all Operating Systems, in all Office Applications or in all architectures(x64/x86). Some libraries may also require external resources (DLL, Addins, etc.) which can be difficult to use due to VBA's lack of a package manager. To help you in finding projects suitable for your needs, this awesome list uses the following symbology. The symbology also has tooltips which may provide more information.
- All applications
- Word
- Excel
- Access
- Outlook
- PowerPoint
- Miscellaneous applications (MS Project, AutoCAD, etc.) - Specify in short description
- 32-bit only
- Written in VBA but the code is password protected
- Requires external dependencies e.g.
.dll
,.ocx
,.o
, etc.- Requires installation
- Link includes/leads to paid content
