Hi,

I am working on a peice of software which has expodentially grown over the last few years and the database needs to be regularly updated. Customers are providing us with data now on large spreadsheets which we format and will start importing into the database. I am using the Import and Export Data (32-bit) Wizard. One column in the database contains values like '1.1.1.2' etc and i am importing them in as a Varchar as that is the data type in the database. However, for values like '8.5', 'NULL' is getting imported insead. It only occurs when there is one decimal point.

Is this a formatting error with excel or is it the wrong datatype?
