Octoparse is a desktop application that can be used to scrape content from any website. They have a visual selector that selects data sections from the source websites and it allows you to download the data in .csv or .xls format.
Next question is to upload this data to your wordpress site, so there is a good plugin called - wpallimport
It will help you import all the data in your website.
Sounds like a big hassle, isn't it?
Well, if you want to avoid all these troubles then try a plugin named - WordPress Automatic Plugin by Valvepress. It smoothly imports data from other websites right into your wordpress.
Why I shared these two methods?
See, both these methods have their pros and cons. You have to take some time to judge them and use as per your needs.
All the best mate!
