This program takes a Microsoft Excel spreadsheet and turns it into an editable table over the internet for you!
How you say? WELL, you must first save your Excel spreadsheet as a *.xml file. To do this, open your spreadsheet in Microsoft Excel, go to "File - Save As..." and pick the folder you wish to save your document to. In the "Save As Type" selection box, choose "XML Spreadsheet (*.xml)" -- NOT XML Data! Then Save.
Once saved, click the Browse button in the upper left of this window and find your file. Then click Upload. It's that easy!
