Getting error while extracting data from an excel

Hi All,

While extracting data from an excel sheet to a table column i am getting an error as below.

[OLE DB Source [228]] Error: There was an error with output column "Acquisition Details" (1222) on output "OLE DB Source Output" (238). The column status returned was: "Text was truncated or one or more characters had no match in the target code page.".

My table column's data type is  [nvarchar](max) NULL.

I think my source data is big enough not to fit in the table column.I don't have permission to change the data type of the particular column. 

Any suggestion/solution/work around will be highly appreciable.

Thanks in advance.
