Importing Classified Ads from csv file to Premium Press Theme

Hi,

I currently have a php based classified ads website (www.bnsads.com). I recently have purchased Wp based classified ads website that is using Premium Press Theme (www.thatsit.com.pk). I now want to import all my classified ads with associated pictures from https://www.bnsads.com to https://www.thatsit.com.pk. Will this plugin work for me? If not, can you help? I can get a csv file generated from my existing website (www.bnsads.com), to be imported into my new website (www.thasit.com.pk), provided I know what should be in that file.
