hi,
the data which is coming from excel is not an unicode format!
by default size would be around 255 char;
so go with the same conversion component, for eg.,
integer--> four byte signed int, like that we have to mention
for strings--> str[4 byte], like that choose the best format which you can find as the suggesion in the error component!
otherwise do the reverse thing, change the data type in dbo.table;
made easy:)
