Hello, hope you are fine today,
This is interesting project. I will have to program my own routine in PHP to import data to MySQL.
1. I will create test live site for this project we can both access (on my vps and some subdomain i own)
2. Import will be tested on this independently hosted live site before it is applied to your site
3. I will write my own PHP routine for this task, there are some plugins for this - i will check that also.
I am giving this project more days then it needs - just in case.
Thanks,
Nebojsa Zivkovic
