As a fact, if you installed Microsoft Excel 2003 on your PC, you will not be able to open a Microsoft Excel file created with Microsoft Office 2007. Excel documents created with Office 2003 ends with .xls while those created with Office 2007 ends with .xlsx.
If you would like to open, edit, and save workbooks that were created in the newer versions Excel with Excel 2003, you either install Microsoft compatibility pack or use a free online document conversion service.
In this post, I am sharing with you how to use zamzar.com, a free online file converter which I use to convert .xlsx files to .xls files.
STEPS FOR EXCEL FILE CONVERSION
==> Go to www.zamzar.com on your PC
==> Use the "Browse" button to select the file you want to convert
==> Choose the format you want to convert to. In this instance, you choose "xls" as seen in the picture below:
==> Enter your email address and click convert.
==> After some minutes, check your email inbox and you should receive an email from zamzar.com
==> Click the download link in the email to download the converted file.
You should now be able to open the file with your Microsoft Excel 2003.
I hope it helps.
In my future posts,I will share with you how to install the Microsoft compatability pack, so you can be opening .xlsx files with your Excel 2003 without converting the documents online. Just SUBSCRIBE to my blog for you not to miss this.
