For instance, the component will tell you if your CSV has values for a drop-down field that do not match the available options for that drop-down in K2.
I work on Mac and I realized that Excel creates CSV files that are not UTF8 and the new line character is Classic Mac (CR). I had to convert the TXT to UTF8 with Windows (CRLF) end-of-line character to be able to use the CSV with this component. I used TextWrangler to do that. The component failed whenever I tried to upload a CSV with Mac (CR) end-of-lines.
Thank you again for this component, great job !!!
