Frequently Asked Questions

Get answers to common questions about our Excel add-in development services.

What is an Excel Add-in?

An Excel Add-in is a custom program that adds new features and capabilities to Excel, such as automated data processing, custom functions, and live data connections.

Why should we hire your Excel add-in development company?

With 20+ delivered projects and deep expertise in both legacy VBA, COM Based VSTO Add-in’s and modern OfficeJS JavaScript API based Add-ins, we deliver robust, scalable, and secure automation solutions.

 

What is the difference between a VBA macro and a JavaScript API add-in?

VBA macros are file-specific and older technology. JavaScript API add-ins are modern, web-based, more secure, and work across Excel on Windows, Mac, and Excel online.

What is the difference between a COM/VSTO Add-in and an Office JS Web Add-in?

COM/VSTO Add-ins are Windows-only and built using .NET technologies, tightly integrated with the desktop version of Office. Office JS Web Add-ins, on the other hand, are cross-platform, web-based, and run on Windows, Mac, and Office on the web using modern web technologies like HTML, CSS, and JavaScript.

Can you make an add-in that connects Excel to our database?

Absolutely. We regularly build add-ins that connect Excel to SQL Server, Oracle, MySQL, REST APIs, and other enterprise data sources.

 

How secure is the business logic in a custom add-in?

We implement enterprise-grade security, including code obfuscation, secure authentication protocols, and data encryption to protect your intellectual property.

Can you modernize our existing collection of VBA macros?

Yes, we specialize in migrating legacy VBA systems to modern, maintainable, and cross-platform JavaScript API add-ins.

 

Will the add-in work with Excel Online and the mobile app?

Add-ins built with the modern JavaScript API work seamlessly across all platforms: Excel for Windows, Mac, Online, and mobile.

 

What kind of complex tasks can you automate?

We automate financial modeling, data cleansing, report generation, predictive analytics, and any repetitive calculation or data manipulation task.

Do you provide support after the add-in is developed?

Yes, we offer ongoing support, maintenance, and enhancement services to ensure your automation solution evolves with your business needs.
