Create, edit, and manage connections to external data

You can use Excel to create and edit connections to external data sources that are stored in a workbook or in a connection file. You can easily manage these connections, including creating, editing, and deleting them using the current Queries & Connections pane or the Workbook Connections dialog box (available in previous versions).
