Hi, I Have an file (ISO File) of ms office 13, but I'm unable to convert it into .exe file, please tell how can I change it what process I have to follow?

You cannot convert to an executable as it is a image file.
You need an extraction or burning prorgam.

So please tell me how can I get it extraction, through winrar or any any other program?

ISO files are generally used as CD or DVD images. The easiest thing to do is to burn the ISO file to a CD or DVD (based on the size--less than 700MB use CD). Once the disk is burned, insert it into the target computer and run the installation program.

Hope this helps,

You can use this free program to extract the contacts and install the program: The Official ImgBurn Website

If the Office program is pirated be very careful.
