devart-excelonline-connector 1.1.0

New level of functionality and performance in data access via Python

Python Connector for Microsoft Excel Online

Python Connector for Microsoft Excel Online is a connectivity solution for accessing Microsoft Excel Online from Python applications to read and update data. It fully implements the Python DB API 2.0 specification. The connector is distributed as a wheel package for Windows and Windows Server.

Standard SQL syntax

The connector fully supports the ANSI SQL standard and lets you execute SQL statements against your Microsoft Excel Online data just like you would normally work with relational databases. Simple queries are directly converted to Microsoft Excel Online API calls and executed on the Microsoft Excel Online side.

Connecting

To connect to Microsoft Excel Online, import the connector and use the connect() method with your connection parameters.

Import the connector

First, import the Microsoft Excel Online connector module:

import devart.excelonline as excelonline

Establish a connection

Call the connect() method and obtain a connection object.

response = excelonline.signin()
my_workbook = excelonline.getworkbook()
my_connection = excelonline.connect(
    WorkbookId=my_workbook["Workbook Id"]
    RefreshToken=response["Refresh Token"]
)

Replace the example values with your actual connection values.

Querying data

Once connected to Microsoft Excel Online, you can execute SQL queries to retrieve data from your Excel workbooks.

Execute a query

Create a cursor object using the cursor() connection method.

my_cursor = my_connection.cursor()

Execute a SQL query using the execute() cursor method.

my_cursor.execute("SELECT * FROM all_types")

Retrieve results using one of the fetch*() methods.

for row in my_cursor.fetchall(): 
    print(row)

Parameterized queries

You can use parameterized queries to pass variable values to your SQL statements. This allows you to reuse the same query with different data and helps to prevent SQL injection attacks.

Pass parameters as a list or tuple to the execute() method:

query = "SELECT Id, Name FROM Contact WHERE Name = ? AND Email = ?"
params = ["Jordan Sanders", "[e-mail]"]
my_cursor.execute(query, params)
results = my_cursor.fetchall()
for row in results:
    print(row)

Each placeholder ? in the query is replaced with a corresponding value from the parameter list.
