Introduction
How many times a day do your employees switch between Outlook, Excel, and your CRM or ERP? These constant back-and-forths harm concentration and productivity. The solution often lies in direct integration via Office Add-ins.
What is an Office Add-in?
An Office Add-in is a web application that runs inside Microsoft 365 applications (Outlook, Word, Excel, PowerPoint). Unlike old VBA macros, modern Add-ins use standard web technologies (HTML, JavaScript/TypeScript, React) and work on all platforms: Windows, Mac, Web, and Mobile.
Concrete use cases
CRM integration in Outlook is a prime example. Imagine receiving an email from a prospect: with a custom Add-in, a side panel automatically opens to display the client's history from your CRM (Salesforce, Dynamics, or in-house solution). You can create an opportunity or archive the email in one click, without ever leaving Outlook.
Document generation in Word is also transformed. For legal or HR departments, contract creation is repetitive. A Word Add-in can retrieve variable data (name, address, dates) from a database and automatically fill a template, ensuring compliance and saving precious time.
Finally, data analysis in Excel becomes smoother. Connect Excel directly to your internal APIs to import financial data in real-time, without manual and risky CSV exports. The Add-in can also offer custom functions for specific business calculations.
Why develop a custom Add-in?
Custom development offers a seamless user experience because the tool integrates where users are already working. Maintenance is simplified since, being web applications, updates are deployed centrally without intervention on client workstations. Finally, security is reinforced as Add-ins run in a secure sandbox and respect the organization's policies.
