NOTE: When uploading an Excel file, please ensure it does NOT have any formulas in the cells. This will cause the file to reject and potentially not allow the log file to be accessed.
Make sure you name your file according to the naming conventions outlined in the upload specifications (ctc_exam_postfix.xlsx, where <postfix> is a required free text field of up to 50 characters).
Once your file is ready, follow the Data File Uploads process to upload the file to the registry. Be sure to check the file status after the file has been processed to see if there are errors you need to investigate or correct.
