Excel 2000

  • Excel 97-2003 Xls files with ACE OLEDB 12.0

    You can use this connection string to use the Office 2007 OLEDB driver (ACE 12.0) to connect to older 97-2003 Excel workbooks.

    Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myOldExcelFile.xls;
    Extended Properties
    ="Excel 8.0;HDR=YES";

    "HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

Excel 2002

  • Excel 97-2003 Xls files with ACE OLEDB 12.0

    You can use this connection string to use the Office 2007 OLEDB driver (ACE 12.0) to connect to older 97-2003 Excel workbooks.

    Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myOldExcelFile.xls;
    Extended Properties
    ="Excel 8.0;HDR=YES";

    "HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

Excel 2003

  • Excel 97-2003 Xls files with ACE OLEDB 12.0

    You can use this connection string to use the Office 2007 OLEDB driver (ACE 12.0) to connect to older 97-2003 Excel workbooks.

    Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myOldExcelFile.xls;
    Extended Properties
    ="Excel 8.0;HDR=YES";

    "HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

Excel 2007

  • Xlsx files

    Connect to Excel 2007 (and later) files with the Xlsx file extension. That is the Office Open XML format with macros disabled.

    Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsx;
    Extended Properties
    ="Excel 12.0 Xml;HDR=YES";

    "HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

  • Treating data as text

    Use this one when you want to treat all data in the file as text, overriding Excels column type "General" to guess what type of data is in the column.

    Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\myFolder\myExcel2007file.xlsx;
    Extended Properties
    ="Excel 12.0 Xml;HDR=YES;IMEX=1";

    If you want to read the column headers into the result set (using HDR=NO even though there is a header) and the column data is numeric, use IMEX=1 to avoid crash.

    To always use IMEX=1 is a safer way to retrieve data for mixed data columns. Consider the scenario that one Excel file might work fine cause that file's data causes the driver to guess one data type while another file, containing other data, causes the driver to guess another data type. This can cause your app to crash.

  • Xlsb files

    Connect to Excel 2007 (and later) files with the Xlsb file extension. That is the Office Open XML format saved in a binary format. I e the structure is similar but it's not saved in a text readable format as the Xlsx files and can improve performance if the file contains a lot of data.

    Provider=Microsoft.ACE.OLEDB.12.0;
    Data Source
    =c:\myFolder\myBinaryExcel2007file.xlsb;
    Extended Properties
    ="Excel 12.0;HDR=YES";

    You can also use this connection string to connect to older 97-2003 Excel workbooks.

    "HDR=Yes;" indicates that the first row contains columnnames, not data. "HDR=No;" indicates the opposite.

  • Xlsm files

    Extended Properties

  • With database password

    This is the connection string to use when you have an Access 2007 - 2013 database protected with a password using the "Set Database Password" function in Access.

    Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccessFile.accdb;

    =MyDbPassword;

    Some reports of problems with password longer than 14 characters. Also that some characters might cause trouble. If you are having problems, try change password to a short one with normal characters.

    Note! Reports say that a database encrypted using Access 2010 - 2013 default encryption scheme does not work with this connection string. In Access; try options and choose 2007 encryption method instead. That should make it work. We do not know of any other solution. Please get in touch if other solutions is available!
