Transfer Data from Excel to Google Data Catalog

This article explains how to transfer data from Excel to Google Data Catalog using the Excel Add-In for Google Data Catalog.

The CData Excel Add-In for Google Data Catalog enables you to edit and save Google Data Catalog data directly from Excel. This article explains how to transfer data from Excel to Google Data Catalog. This technique is useful if you want to work on Google Data Catalog data in Excel and update changes, or if you have a whole spreadsheet you want to import into Google Data Catalog. In this example, you will use the Schemas table; however, the same process will work for any table that can be retrieved by the CData Excel Add-In.

Establish a Connection

If you have not already done so, create a new Google Data Catalog connection by clicking From Google Data Catalog on the ribbon.

Google Data Catalog uses the OAuth authentication standard. Authorize access to Google APIs on behalf on individual users or on behalf of users in a domain.

Before connecting, specify the following to identify the organization and project you would like to connect to:

  • OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.

    Click the project selection drop-down, and select your organization from the list. Then, click More -> Settings. The organization ID is displayed on this page.

  • ProjectId: The ID associated with the Google Cloud Platform project resource you would like to connect to.

    Find this by navigating to the cloud console dashboard and selecting your project from the Select from drop-down. The project ID will be present in the Project info card.

When you connect, the OAuth endpoint opens in your default browser. Log in and grant permissions to the application to completes the OAuth process. For more information, refer to the OAuth section in the Help documentation.

Retrieve Data from Google Data Catalog

To insert data into Google Data Catalog, you will first need to retrieve data from the Google Data Catalog table you want to add to. This links the Excel spreadsheet to the Google Data Catalog table selected: After you retrieve data, any changes you make to the data are highlighted in red.

  1. Click the From Google Data Catalog button on the CData ribbon. The Data Selection wizard is displayed.
  2. In the Table or View menu, select the Schemas table.
  3. In the Maximum Rows menu, select the number of rows you want to retrieve. If you want to insert rows, you need to retrieve only one row. The Query box will then display the SQL query that corresponds to your request.
  4. In the Sheet Name box, enter the name for the sheet that will be populated. By default the add-in will create a new sheet with the name of the table.

Insert Rows to Google Data Catalog

After retrieving data, you can add data from an existing spreadsheet in Excel.

  1. In a cell after the last row, enter a formula referencing the corresponding cell from the other spreadsheet; for example, =MySchemasSheetInExcel!A1.
  2. After using a formula to reference the cells you want to add to Google Data Catalog, select the cells that you are inserting data into and drag the formula down as far as needed. The referenced values you want to add will be displayed on the Schemas sheet.
  3. Highlight the rows you want to insert and click the Insert Rows button.

As each row is inserted, the Id value will appear in the Id column and the row's text will change to black, indicating that the record has been inserted.
