Viewing Macros in Excel…
Open the excel document and select file or menu button. Select options menu from the listed menu items. Check the Developer check box from the right side container. Then Developer Tab will be added in menu bar, click on it and select View code. Now you can see the code behind your excel file how it is processing the data. Please open your file in untrusted mode because they can script the file to upload your data in to their server.
Be cautious….:)
