read excel worksheet to dataset and numeric cells are changed to exponential

1 New Member
I have one problem regarding format of mixed data columns in excel. I am using ADO.NET to retrieve data from excel sheet.
Connection String used is:
Provider=Micros oft.Jet.OLEDB.4 .0;Data Source=c:\\ITEM .xls;Extended Properties=\"Ex cel 8.0;HDR=YES;IME X=1\"

I am able to retrieve all data (numeric and text), but for cells which contains numeric (with greater than 8 digits) I am getting wrong values.

Excel sheet ado.net converts to
15106749310-> 1.51067e+010
70400672657-> 7.04007e+010
48110753143-> 4.81108e+010

If I use "Format([columnName], '####') As [ColumnName]", in the query then it is rounded off.

I have numeric and text data both in same column and I have formatted the cells as text.
If I add single quote (‘) at the beginning of the data (numeric) they are retrieving correct.
But this is not a better way of export from excel as I am exporting thousands of records.

Could anyone please help me to get the correct value from excel asap.
