I am reading data from excel file, one of its column is having alphanumeric value in it. Alpha numeric column has first 200 rows as numeric and rest of the rows are text. While reading the data from excel file, numeric values are coming properly but the text values are appering as NULL. I have changed the column type as text and have used the IMEX = 1 flag as well in the Connection string setting but still its not working. Can somebody provide me the solution.
