What do users say?

"Appvantage uses LibXL to produce true Excel sheets (.xlsx files) blisteringly fast in their DataFlex applications. Templates are used for defining the layout and formulas are invoked dynamically, creating Excel formulas.

Senf Theaterpartners use them for example for pre-calculations, attendance statistics and sales reports. Users could omit, or add columns but this is usually not required. The use of LibXL is highly appreciated at Senf Theaterpartners. It contributes to a positive user experience of the DataFlex application as a whole."
