D4J User Sync Joomla! extension allows you to import users from CSV file to Joomla! user database and, vice versa, export users from the database to CSV file. You can define your own rule and hence make User Sync to process virtually all kind of CSV file.

Besides of definition custom processing rule you can define series of other parameters such as fields termination symbol, fields enclosing symbol, etc. This can really expand the amount of CSV file types you are able to process.
One of the hottest feature is the possibility of definition processing rule for any available user types including those which were installed by third-party component. You just need to define corresponding pair CSV User Group <=> Joomla User Group and User Sync will do its job.
