Ways of Opening Microsoft Excel Workbooks (.xls)

1. Opening through ODBC DSN (interface: ADO or BDE). Select 'ODBC data source' option and then select the ODBC DSN from the dropdown list. But first, you should create an ODBC DSN of the corresponding type using Windows administrative tools, and point it to the database file.

2. Opening by specifying file name (interface: ADO). Select 'File' option and then browse for the needed file.

3. Opening through connection string (interface: ADO). Select 'Connection string' option and write a connection string. This way is the most flexible one because it is possible to specify many additional parameters in the connection string, but it is recommended basically for advanced users. Here are basic connection strings (more examples and details can be found in the Internet):

Provider=Microsoft.Jet.OLEDB.4.0;excel 8.0;DATABASE=C:\MyData\MyExcelData.xls;

Provider=MSDASQL.1;Extended Properties="DBQ=C:\MyData\MyExcelFile.xls;DefaultDir=C:\MyData;Driver={Microsoft Excel Driver (*.xls)};DriverId=790;"

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\MyData\MyExcelFile.xls;Extended Properties="Excel 8.0;HDR=YES";   (Microsoft ACE must be installed)

Notes
Sometimes, after opening Excel workbooks, you may see no tables in the file. If you are sure the file has data, try to open it by it's native program, assign name(s) to needed cell range(s), save, and then try to open it in Database Tour again. If the result is unsuccessful, try to open the file by direct specifying connection string with different parameters: for example, change ODBC-based string to Jet-based one (the differences are shown in examples of connection strings).
