Seamlessly imported (and edited) 900+ users with many custom fields!

I had to transfer 900+ users of an old website (not WP), furthermore the target project is full of custom fields, extra user roles and further data.

After exporting some test users on a CSV file I checked and edited all the field names in order to match my new WP website structure.
The final import of all 900+ users was quick and precise.
Everything smooth like oil.

Anything you can imagine to export on a CSV file can be easily imported into WP, you just need to be very precise and careful with the names of the columns you need to import.
Just remember: username and email columns MUST be the first ones in any import file!
