I had a chance to play with the Syncfusions XLsIO components for my reporting export needs. There are a bunch of controls and features which helps make the UI really appealing. The controls are easy to work with and render perfectly.
I had a requirement to create a web-based application that would create two pivot tables. The data source was SQL Server and the user had to be able to filter the data before populating the workbook. The XlsIO solution was both elegant and simple.
I've been using Syncfusion Essential XlsIO for over 7 years now. I recently started a new project and needed to be able to import data from differently formatted Excel documents. XlsIO has a great method to return the contents of an Excel sheet as a DataTable.
Our previous excel solution was feature incomplete - the reports that were generated by the excel export engine did not look anything like the reports we produced on the web. After switching to XlsIO we can produce excel reports that are nearly identical to the ones we produce on the web.
We are using Syncfusion GridGrouping, Grid controls, DockingManager and a couple of other controls. All these have a rich functionality and are very flexible due to their elegant design.
