FAQ
What types of Office Add-ins do you develop?
I develop custom Office Add-ins for Outlook, Excel, Word, and PowerPoint, including task automation, document interaction, UI customization, and smart AI features. All add-ins are fully compatible with Office 365 on desktop, web, and mobile.
Can you integrate AI tools like ChatGPT into Office 365 Add-ins?
Yes, I can integrate OpenAI (ChatGPT) into your Office Add-ins to enable smart replies, task automation, and intelligent productivity features. This is ideal for improving user experience and efficiency.
Do your add-ins support enterprise security?
Absolutely. All Office 365 Add-ins are built with Microsoft Graph API, Azure Active Directory, and OAuth2 for secure authentication and data access, following enterprise-grade security standards.
What technologies do you use for Office Add-in development?
I use JavaScript, TypeScript, React, MUI (Material-UI), Fluent UI, and the Microsoft Office JavaScript API for frontend development. For backend systems, I use Node.js and MongoDB to build scalable, secure, and high-performance solutions.
Will the Office Add-in work across devices?
Yes, I ensure that every Outlook Add-in, Excel Add-in, or Word Add-in is fully functional across Office 365 desktop, web, and mobile platforms.
Can you customize an existing Office Add-in?
Yes, I can enhance, debug, or add new features to your existing Office 365 Add-ins—whether it's an Outlook, Excel, or Word integration.
How long does it take to build a custom Office Add-in?
Delivery time depends on the complexity of your requirements. Simple Outlook or Excel Add-ins can be done within a few days, while complex integrations may take longer. I’ll provide a clear estimate after reviewing your needs.
