I had the same issue  multiple data type values in single column  package load only numeric values  Remains all it updated as null    Solution  To fix this changing the excel data type is one of the solution  In Excel Copy the column data and paste in different file  Delete that column and insert new column as Text datatype and paste that copied data in new column   Now in ssis package delete and recreate the Excel source and destination table change the column data type as varchar   This will work

Try this one as it worked for me      SSIS - the value cannot be converted because of a potential loss of data

When you first set up this package  I am guessing that either a one or two digit number was the first value in the ShipTo column   Your package reading from the Excel picked a numeric type for that input field and the word  ALL  fails the package since the input spec for that field is numeric   There are several ways to fix this beforehand  but to fix it after the fact  the easiest way is to right click the Excel Source and choose Show Advanced Editor     From there  choose the tab that says Input and Output Properties   In the topmost part of the inputs and outputs section of that dialog box  find the column ShipTo   You will have to drill down to find it   Set the DataType  to  string  DT STR   and the length to 20   Click OK then attempt to run your package again

This might not be the best method  but you can ignore the conversion error if all else fails  Mine was an issue of nulls not converting properly  so I just ignored the error and the dates came in as dates and the nulls came in as nulls  so no data quality issues--not that this would always be the case  To do this  right click on your source  click Edit  then Error Output  Go to the column that s giving you grief and under Error change it to Ignore Failure

For me just removed the OLE DB source from SSIS and added again  Worked
