Export/import tool for opencart version 1.5.6.4 ?

I have installed Opencart version 1.5.6.4, and would like to install the Export/Import Tool by Jeff Neuhoff, but on the download page the latest Opencart version shown is 1.5.6.1 (vers 17). I am afraid to install this in case it hoses my site.

Could someone please advise? Or recommend an alternative tool for bulk uploading of products?

Thank you sincerely in advance.

There is alternative software - Store Manager for OpenCart. Full version is payed one, but is comes in trial version with the same functionality which you can use for 14-days, so basically if you need to import products once and in bulk, you can make it with trial version. Download free version and give it a try: http://www.opencartmanager.com/free-download
Maybe you will like it.
