excel – ODBC xlsx driver connectionstring without header

Posted by: admin May 14, 2020 Leave a comment


I am connecting to xlsx files via ODBC with following command:

"DRIVER=Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb);HDR=YES;IMEX=1;READONLY=TRUE;DBQ=C:\Temp\test.xlsx"

It works fine but I am always missing one line when there is no header in the file.
Obviously it’s because of the parameter “HDR=YES” but I cant figure out how to disable the header line.

I have tried “HDR=NO” and leaving this parameter out
but no effect.
I can access to the file but I always lose the first line.

Can somebody help me with that?


How to&Answers:

I did some research.

If you open a XLS or XLSX file via a driver like

"DRIVER=Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb);HDR=YES;IMEX=1;READONLY=TRUE;DBQ=C:\Temp\test.xlsx"

the driver is ignoring parameters completly.
So “HDR=NO” has no effect.

Apparently the driver uses a setting in the registry to determine if the first line should be interpreted as an header line.

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office.0\Access Connectivity Engine\Engines\Excel

So if you set FirstRowHasNames=00 the first line wont be skipped.
