Excel
The Provider for Microsoft Excel allows connecting to local and remote Excel resources. Set the URI property to the Excel resource location, in addition to any other properties necessary to connect to your data source.
Connecting to Cloud-Hosted Microsoft Excel Files
While the provider is capable of pulling data from Microsoft Excel files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this provider.
If you need INSERT/UPDATE/DELETE cloud files, you can download the corresponding CData provider for that cloud host (supported via stored procedures), make changes with the local file's corresponding provider, then upload the file using the cloud source's stored procedures.
As an example, if you wanted to update a file stored on SharePoint, you could use the CData SharePoint provider's DownloadDocument procedure to download the Microsoft Excel file, update the local Microsoft Excel file with the CData Microsoft Excel provider, then use the SharePoint provider's UploadDocument procedure to upload the changed file to SharePoint.
A unique prefix at the beginning of the URI connection property is used to identify the cloud data store being targed by the provider and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table).
