Opening a connection to a Microsoft Excel spreadsheet (e.g. *.xls) is achieved using the Microsoft Excel driver, typically called 'Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)'. Unfortunately, this driver is available only on Windows, not Unix.
The easiest way to check if the driver is available to your Python environment (on Windows) is to use
The resulting list will show any matching drivers, e.g.,
You can also check for the driver on your PC by navigating to Control Panel -> Administrative Tools -> Data Sources (ODBC), and then click on the 'Drivers' tab. The Excel driver will be listed there, if it is installed. It may have a slightly different name. Note also that there are separate 64-bit and 32-bit versions of the ODBC Administrator utility (odbcad32.exe).
The Microsoft Excel driver does not support transactions, so you must set autocommit to True on the connection or else you will get an error, e.g.:
Excel defaults to a read-only connection, so if you want to update the spreadsheet include ReadOnly=0 in your connection string:
Be careful of the data types in your Excel spreadsheet. The Excel driver uses the most common data type from the first 8 rows of the spreadsheet to determine the data type of each column. So if you have 5 numbers and 3 text values in the first rows of a column, the column will be considered numeric, and the 3 text values will be returned as NULL!
Also, the driver may treat the first row of the worksheet as the column names, rather than data, so be aware of this.
Overall though, it has to be said, Excel is not best suited for being accessed with an ODBC connection. You may want to consider using some other Python module instead of pyodbc, for example xlrd.

Again, you may be required to restart your computer upon completion of the install. Choose which version of Microsoft Windows you’re using — the Windows 7 drivers will work for Windows 8 and — select the operating system language, and click Download.Once the download screen pops up, hit Run and allow the Xbox 360 Accessories Setup program to install the required files. If not, you can download from the link; if wired, select instead. You may need to restart your computer.
