No, our Excel frameworks, are not sold individually, only as a single package. However, we have competitively priced the package so it only costs a little bit more than what some other vendors charge for their Excel alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all the Document Processing libraries for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.

A good place to start would be our comprehensive getting started documentation.

The Syncfusion Excel framework supports platforms for web (Blazor, Flutter, ASP.NET Core, ASP.NET MVC, and ASP.NET Web Forms), mobile (.NET MAUI(preview), Flutter, Xamarin, and UWP), and desktop (Windows Forms, WPF, WinUI, .NET MAUI(preview), Flutter, Xamarin, and UWP).

We do not sell Excel Framework separately. It is only available for purchase as part of the Syncfusion File Formats suite, which also contains libraries for PDF, Word, and PowerPoint. A single developer license for the Syncfusion File Formats suite costs $995.00 USD, including one year of support and updates. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.
