Excel Online ODBC Driver

The Excel Online ODBC Driver is a powerful tool that allows you to connect with live Excel Online data, directly from any applications that support ODBC connectivity.

Access Excel Online Spreadsheet data like you would a database - read, write, and update data through a standard ODBC Driver interface.



Connect to Excel Online as an ODBC data source in PyCharm using the CData ODBC Driver for Excel Online.

The CData ODBC Drivers can be used in any environment that supports loading an ODBC Driver. In this tutorial we will explore using the CData ODBC Driver for Excel Online from within PyCharm. Included are steps for adding the CData ODBC Driver as a data source, as well as basic PyCharm code to query the data source and display results.

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for Excel Online as well as PyCharm.

Add Pyodbc to the Project

Follow the steps below to add the pyodbc module to your project.

  1. Click File -> Settings to open the project settings window.
  2. Click Project Interpreter from the Project: YourProjectName menu.
  3. To add pyodbc, click the + button and enter pyodbc.
  4. Click Install Package to install pyodbc.

Connect to Excel Online

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

You can connect to a workbook by providing authentication to Excel Online and then setting the following properties:

  • Workbook: Set this to the name or Id of the workbook.

    If you want to view a list of information about the available workbooks, execute a query to the Workbooks view after you authenticate.

  • UseSandbox: Set this to true if you are connecting to a workbook in a sandbox account. Otherwise, leave this blank to connect to a production account.

You use the OAuth authentication standard to authenticate to Excel Online. See the Getting Started section in the help documentation for a guide. Getting Started also guides you through executing SQL to worksheets and ranges.

Below is the syntax for a DSN:

[CData ExcelOnline Source] Driver = CData ODBC Driver for Excel Online Description = My Description

Execute SQL to Excel Online

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for ExcelOnline};') cursor = cnxn.cursor() cursor.execute("SELECT Id, Column1 FROM Test_xlsx_Sheet1 WHERE Column2 = 'Bob'") rows = cursor.fetchall() for row in rows: print(row.Id, row.Column1)

After connecting to Excel Online in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to Excel Online data as if it were a standard database. If you have any questions, comments, or feedback regarding this tutorial, please contact us at support@cdata.com.
