Hi Sakesforce Test 5,

I think the csv must contain a column of ID values and Name field.
If ID is not blank, it will update the record matches the ID, if It is blank, it will insert a new record.

May i see the sample format of your csv file? 

thank you.

Hi Salesforce Test 5,

Have you tried to set the external Id in the process-conf.xml to "Name" field of the custom object? 
<entry key="sfdc.externalIdField" value="Name"/>
