    Outstanding useful. Ada is my favorite language. Excel interaction is a hot feature.

    Quoting Václav D., Czech Republic: "I have compared the speed between Excel Writer and Visual Basic. I have written a Code that generates 50000 rows with 50 Columns. I wrote the number of current column in each cell, that was 2,5 millions of column records. Visual Basic performed this operations in 64 seconds, but Excel Writer in 3,2 seconds that is 20x faster. That is unbelievable!!! Best regards"
