My office is trying to transmit 1099s from the Information Return System to the IRS' new Information Return Intake System (IRIS) which replaces FIRE this year. IRIS requires that the 1099EF DAT file be converted to a CSV file. When we do that the CSV Excel template does not match the IRIS template, and the columns do not populate with the date shown in the DAT file. 

Has anyone had success with this process? If so, can you post what steps you took? Any help is sincerely appreciated.
