*** Download the newest version of tool that even supports TLS 1.2: Bulk User Load/Update Utility - Import Users ***
The Archer Bulk User Uploader (or Import) tool was developed by a member of the Professional Services Team several years ago. It uses many Archer Web Services API methods to quickly create a large number of Archer User Accounts using a delimited source file. The tool can be ran remotely or from the Archer server...it even works with SaaS environments. The attached zip file contains the executable, sample configuration files, and instructions.
