I am using the example from http://msdn.microsoft.com/en-us/library/bb332058(v=office.12).aspx to retrieve values from an excel file. I am retrieving about 1500 values, and it is very slow.
My question does anyone know a better way to retrieve values quickly out of an excel file?
One thing that did save about 6 seconds was not opening the file every time a value was needed but just keep the file open throughout the process. But even doing this it is still taking about 22 seconds for it to complete.
