How to Connect to & Open IBM Cloud Object Storage Data in Microsoft Excel

The CData ODBC driver for IBM Cloud Object Storage uses the standard ODBC interface to link IBM Cloud Object Storage data with applications like Microsoft Access and Excel. Follow the steps below to use Microsoft Query to import IBM Cloud Object Storage data into a spreadsheet and provide values to a parameterized query from cells in a spreadsheet.

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Register a New Instance of Cloud Object Storage

If you do not already have Cloud Object Storage in your IBM Cloud account, follow the procedure below to install an instance of SQL Query in your account:

1. Log in to your IBM Cloud account.
2. Navigate to the page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.

Connecting using OAuth Authentication

There are certain connection properties you need to set before you can connect. You can obtain these as follows:

API Key

To connect with IBM Cloud Object Storage, you need an API Key. You can obtain this as follows:

1. Log in to your IBM Cloud account.
2. Navigate to the Platform API Keys page.
3. On the middle-right corner click "Create an IBM Cloud API Key" to create a new API Key.
4. In the pop-up window, specify the API Key name and click "Create". Note the API Key as you can never access it again from the dashboard.

Cloud Object Storage CRN

If you have multiple accounts, you will need to specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:

• Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
• Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.

Connecting to Data

You can now set the following to connect to data:

• InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
• ApiKey: Set this to your API key which was noted during setup.
• CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the connector attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than Cloud Object Storage account.

When you connect, the connector completes the OAuth process.

1. Extracts the access token and authenticates requests.
2. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.

You can then work with live IBM Cloud Object Storage data in Excel.

1. In Excel, open the Data tab and choose Get Data -> From Other Sources -> From Microsoft Query.
2. Choose the IBMCloudObjectStorage DSN. Select the option to use Query Wizard to create/edit queries.
3. In the Query Wizard, expand the node for the table you would like to import into your spreadsheet. Select the columns you want to import and click the arrow to add them to your query. Alternatively, select the table name to add all columns for that table.
4. The Filter Data page allows you to specify criteria. For example, you can limit results by setting a date range.
5. If you want to use parameters in your query, select the option to edit the query in Microsoft Query.

6. To set a parameter in the query, you will need to modify the SQL statement directly. To do this, click the SQL button in the Query Editor. If you set filter criteria earlier, you should have a WHERE clause already in the query.

   To use a parameter, use a "?" character as the wildcard character for a field's value in the WHERE clause. For example, if you are importing the Objects, you can set "Bucket=?".

7. Close the SQL dialog when you are finished editing the SQL statement. You will be prompted to enter a parameter value. In the next step, you will select a cell to provide this value. So, leave the box in the dialog blank.

8. Click File -> Return Data to Microsoft Excel. The Import Data dialog is displayed. Enter a cell where results should be imported.

9. Close the Import Data dialog. You will be prompted to enter a parameter value. Click the button next to the parameter box to select a cell. Select the option to automatically refresh the spreadsheet when the value changes.
