This is a plugin for XrmToolBox. The code is based on the View Layout Replicator.
Even though you can export records from Dynamics CRM, there is a record count limitation. The upper limit is 100,000 in CRM 2015 Update 1 -> http://www.microsoft.com/en-US/dynamics/crm-customer-center/export-data-to-excel.aspx
This tool can be used to overcome that limitation, as it just pages through RetrieveMultiple till there are no more records to retrieve.
#Install Instructions Download the most recent version of XrmToolBox. Click on the "Plugin Store" button in the menu and install this tool from the store.
