Target Service, API

CData Google Sheets ADO.NET driver allows you to access Google Sheets as tables. The driver leverages two drivers: the Google Drive API to enable bidirectional access to Google Sheets and the Google Sheets to retrieve the actual data.

Schema, Data Model

The driver models spreadsheets and ranges as relational tables. The driver enables you to represent a top-left-oriented spreadsheet or a user-specified range as a database table. You can control how tables are listed by setting the Header property.

Key Objects

User defined sheets are being exposed as tables.

Operations

The driver supports standard operations (SELECT, INSERT, UPDATE, DELETE) and bulk operations (INSERT INTO SELECT, UPDATE SELECT, DELETE SELECT).

Authentication

CData provides an embedded OAuth application that simplifies authentication at the desktop. You can also authenticate from the desktop via a custom OAuth application, which you configure and register at the Google Sheets console.. Supported Authentication Schemes are; Token, OAuth, OAuthJWT, GCPInstanceAccount, AWSWorkloadIdentity

Standard ADO.NET Access to GoogleSheets

The Google Sheets ADO.NET Provider offers the most natural way to access Google Sheets data from any .NET application. Simply use Google Sheets Data Provider objects to connect and access data just as you would access any traditional database. You will be able to use the Google Sheets Data Provider through Visual Studio Server Explorer, in code through familiar classes, and in data controls like DataGridView, GridView, DataSet, etc.

The CData ADO.NET Provider for Google Spreadsheets hides the complexity of accessing data and provides additional powerful security features, smart caching, batching, socket management, and more.

Working with DataAdapters, DataSets, DataTables, etc.

The Google Sheets Data Provider has the same ADO.NET architecture as the native .NET data providers for SQL Server and OLEDB, including: GoogleSheetsConnection, GoogleSheetsCommand, GoogleSheetsDataAdapter, GoogleSheetsDataReader, GoogleSheetsDataSource, GoogleSheetsParameter, etc. Because of this you can now access Google Sheets data in an easy, familiar way.

For example:

using (GoogleSheetsConnection conn = new GoogleSheetsConnection("...")) {
	string select = "SELECT * FROM GoogleSpreadsheet";
	GoogleSheetsCommand cmd = new GoogleSheetsCommand(select, conn);
	GoogleSheetsDataAdapter adapter = new GoogleSheetsDataAdapter(cmd);
	using (adapter) {
		DataTable table = new DataTable();
		adapter.Fill(table);		
		...
	}
}

More Than Read-Only: Full Update/CRUD Support

Google Sheets Data Provider goes beyond read-only functionality to deliver full support for Create, Read, Update, and Delete operations (CRUD). Your end-users can interact with the data presented by the Google Sheets Data Provider as easily as interacting with a database table. 

using (GoogleSheetsConnection connection = new GoogleSheetsConnection(connectionString)) {
	GoogleSheetsDataAdapter dataAdapter = new GoogleSheetsDataAdapter(
	"SELECT Id, Where FROM GoogleSpreadsheet", connection);
  
	dataAdapter.UpdateCommand = new GoogleSheetsCommand(
		"UPDATE GoogleSpreadsheet SET Where = @Where " +
		"WHERE Id = @ID", connection);

	dataAdapter.UpdateCommand.Parameters.AddWithValue("@Where", "Where");
	dataAdapter.UpdateCommand.Parameters.AddWithValue("@Id", "80000173-1387137645");

	DataTable GoogleSpreadsheetTable = new DataTable();
	dataAdapter.Fill(GoogleSpreadsheetTable);

	DataRow firstrow = GoogleSpreadsheetTable.Rows[0];
	firstrow["Where"] = "New Location";

	dataAdapter.Update(GoogleSpreadsheetTable);
}

ADO.NET Provider Performance

With traditional approaches to remote access, performance bottlenecks can spell disaster for applications. Regardless if an application is created for internal use, a commercial project, web, or mobile application, slow performance can rapidly lead to project failure. Accessing data from any remote source has the potential to create these problems. Common issues include:

  1. Network Connections - Slow network connections and latency issues are common in mobile applications.
  2. Service Delays - Delays due to service interruptions, resulting in server hardware or software updates.
  3. Large Data - Intentional or unintentional requests for large amounts of data.
  4. Disconnects - Complete loss of network connectivity.

The CData ADO.NET Provider for Google Spreadsheets solves these issues by supporting powerful smart caching technology that can greatly improve the performance and dramatically reduce application bottlenecks.

Smart Caching

Smart caching is a configurable option that works by storing queried data into a local database. Enabling smart caching creates a persistent local cache database that contains a replica of data retrieved from the remote source. The cache database is small, lightweight, blazing-fast, and it can be shared by multiple connections as persistent storage.

Caching with our ADO.NET Providers is highly configurable, including options for:

  • Auto Cache - Maintain an automatic local cache of data on all requests. The provider will automatically load data into the cache database each time you execute a SELECT query. Each row returned by the query will be inserted or updated as necessary into the corresponding table in the cache database.
  • Explicit Cache - Cache only on demand. Developers decide exactly what data gets stored in the cache and when it is updated. Explicit caching provides full control over the cache contents by using explicit execution of CACHE statements.
  • No Cache - All requests access only live data and no local cache file is created.

This powerful caching functionality increases application performance and allows applications to disconnect and continue limited functioning without writing code for additional local storage and/or data serialization/deserialization.

More information about ADO.NET Provider caching and best caching practices is available in the included help files.
