Take your Office add-in development to another level
Add-in Express is a true RAD tool that empowers Office add-in developers with a number of unique features that no other tool offers.
Application-level Office extensibility
Use a set of Office-specific solution templates, wizards, visual designers and components to build various types of application-level extensions including:
- Office COM Add-ins
- Excel XLL
- RTD servers
- Automation add-ins
- Smart tags
The version-neutral core of Add-in Express gives Office developers the ability to:
- Write a single code base to support all Office versions, from 2000 to 2013.
- Develop version-independent add-ins with no application-specific solutions, no version-specific projects, no shared assemblies.
- Selective version independence – all you need to do is specify the minimum version of Microsoft Office you want to support.
Visual designers instead of low-level coding
Add-in Express provides a number of in-place visual designers to customize Office menus, toolbars, ribbons, task panes, forms, windows, regions, option and property pages, etc.
- You use an array of components and visual designers to create any UI elements such as the Office Ribbon, Toolbars and Backstage View.
- You can design your Office extension's UI without a single line of code to give your manager or customer the proof of concept in no time.
- You don't need to worry about hand coding any plumbing code, focus on building your solution!
