what is connection string to load excel 2007 file in delphi 7

The connection string to load an Excel 2007 file in Delphi 7 using ADO (ActiveX Data Objects) is as follows:

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Path\To\Excel\File.xlsx;Extended Properties="Excel 12.0 Xml;HDR=YES";

Here, the Provider specifies the OLE DB provider for Excel, Data Source specifies the path to the Excel file, and Extended Properties specifies the version of Excel and whether the first row contains column headers (HDR=YES).

You can use this connection string in a TADOConnection component to establish a connection to the Excel file and retrieve data from it
