As fgetscsv have problems with non UTF8 characters we changed it and now we had problems with commas inside fields, so we have rewritten it using str getcsv and declaring the in case your PHP version doesn't support it.. 1.1.2 fgetscsv have problems with non UTF8 characters, so we have changed it for fgetcsv thanks to user.
Now going through the points above, you should now see new Import users from CSV menu item under Tool in the sidebar of the admin panel, see figure below of how it looks like..
You have to use the serialized string in the CSV order the plugin will be able to understand it as data instead as any other string...
You can use those labels if you want to set data adapted to the WordPress default user columns user nicename string that contains URL-friendly name for the user.
Thanks to @fiddla for debugging all this, as update option with value equals to true is saved as in the database, we couldn't use the == or === operator to see if the option was active or not.
Now you can choose if you want to send the email to all users or only to creted users thanks to Remy Medranda.
Thanks to Matthijs Mons now this plugin is able to work with Allow Multiple Accounts and allow the possibility of register update users with same email instead as using thme in this case as reference to the user as the username.. 1.6.
Thanks to idealien, if we use username to update users, the email can be updated as the rest of the data and metadata of the user and we silence the email changing message generated by core.. 1.5.1.
You can include all this fields in the mail user nicename., user url., display name., nickname., first name., last name., description., jabber., aim., yim., user registered if you used it in the CSV and you indicate it the in this way FIELD NAME, for example first name. 1.4.2.
Thanks to Kristopher Hutchison we have add option to choose what you want to do with empty cells 1 ) delete the meta-data or 2 ) ignore it and do not update, previous to this version, the plugin update the value to empty string. 1.3.9.4.
