Microsoft Excel Spreadsheet Reader
Creates an object to read Microsoft Excel spreadsheets. This is a really easy way to get data out of a Microsoft Excel Spreadsheet. Methods allow for getting the data from a worksheet as a 2 diminsional String array or a specific column from a worksheet as a 1 diminsional String array. It really isn't that complex of code - there is a sample program included to show you exactly how to use it!! If you find this useful, then please VOTE for me at the bottom of this page!
