The Export Users tool allows you to create a list (in a comma-delimited file) of selected registration data from all users in a User Group, or all users on your site in general.

To use it, select the User Group to export, check the boxes next to the fields/columns you want to export, then click the Export Data button at the bottom. Save the resulting CSV file, which may then be opened and viewed in a spreadsheet program such as Microsoft Excel.
