How to import CSV into Custom Post Type custom fields?

I have created a Custom Post Type and then used a plugin to create the custom fields for that post type.

It will display a type of membership:
Name
Address
Zip
Website

But I am stuck on how to take the csv file I have, which has 700 entries and import it to create 700 entries under the CPT I created and autopopulate the custom fields I created.

I tried a lot of plugins, but none seemed to do both parts. Some let me just select the CTP but I couldn´t get all the fields populated.

Just needed to know best way to accomplish this.

I’m using a plugin called TurboCSV (found here, at the time of writing). The plugin offers support to add data to your various custom fields, which need to be created before the import takes place. In my personal use, I was able to successfully import thousands of items from one .csv, including hundreds of taxonomy terms and custom fields.

Have a look at the plugin’s documentation to see how involved it is and how much you’re able to do.
