Solution with Excel 2007+

In Excel 2007, click on the Office Button > Save As...

Then, change the format to .xls (Excel Workbook 97 - 2003).

Solution without any Excel version >2003

Open the Excel 2007 file in Office 2007 and simply, Click on Top Left Ms-Office log and select Save as arrow button not on Save as option and then select Excel 97-2003 option.....It Will Definitely Work For You.
