ActiveReports is a .NET reporting tool used by developers of .NET (cross-platform, WinForms), and ASP.NET/JavaScript (WebForms, MVC 5, Core, Blazor) applications.

It was originally developed by Data Dynamics, which was then acquired by GrapeCity, now known as Mescius.

[citation needed] ActiveReports allows developers to create Windows and Web applications, which allow end-users to create and/or preview complicated reports.

Among the components included with ActiveReports are exports to file formats such as PDF, Excel, RTF, Word and others.

ActiveReports also includes Visual Studio integrated report designer, and an API that developers use to create customized reports from a variety of data sources.
