Replicate Multiple Google Sheets Accounts

Replicate multiple Google Sheets accounts to one or many databases.

CData Sync for Google Sheets is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple Google Sheets connections. In this article we show how to use the CLI to replicate multiple Google Sheets accounts.

Configure Google Sheets Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple Google Sheets accounts, use multiple configuration files. Below is an example configuration to replicate Google Sheets to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>System.Data.SQLite</DatabaseProvider> <ConnectionString>Spreadsheet=MySheet;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> <TaskSchedulerStartTime>09:51</TaskSchedulerStartTime> <TaskSchedulerInterval>Never</TaskSchedulerInterval> </CDataSync>

Java

<?xml version="1.0" encoding="UTF-8" ?> <CDataSync> <DatabaseType>SQLite</DatabaseType> <DatabaseProvider>org.sqlite.JDBC</DatabaseProvider> <ConnectionString>Spreadsheet=MySheet;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

You can connect to a spreadsheet by providing authentication to Google and then setting the Spreadsheet connection property to the name or feed link of the spreadsheet. If you want to view a list of information about the spreadsheets in your Google Drive, execute a query to the Spreadsheets view after you authenticate.

ClientLogin (username/password authentication) has been officially deprecated since April 20, 2012 and is now no longer available. Instead, use the OAuth 2.0 authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

See the Getting Started chapter in the help documentation to connect to Google Sheets from different types of accounts: Google accounts, Google Apps accounts, and accounts using two-step verification.

Configure Queries for Each Google Sheets Instance

Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the Google Sheets API. The statement below caches and incrementally updates a table of Google Sheets data:

REPLICATE Orders;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple Google Sheets accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Orders SELECT * FROM Orders

Alternatively, you can use a different schema:

REPLICATE PROD.Orders SELECT * FROM Orders

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

GoogleSheetsSync.exe -g MyProductionGoogleSheetsConfig.xml -f MyProductionGoogleSheetsSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar GoogleSheetsSync.jar -g MyProductionGoogleSheetsConfig.xml -f MyProductionGoogleSheetsSync.sql
