Workbook connections allow workbooks to import and reference external data from various sources like ODBC, OLEDB, ADO, DAO, text files, and the web. Objects in Excel like query tables, tables, pivot tables, and OLAP functions can consume data through connections that reference a unique connection ID. Different connection types support importing data from SQL databases, text files, and web queries.
