Sorry to resurrect this thread!
We have this exact problem. LEA have provided admissions info, however we have the additional information we require for admission automatically populated in a spreadsheet via an online form that the parents complete. We would like to be able to take this spreadsheet and import it to SIMS, whether that's as a CSV or potentially an ATF. Does anyone have a blank ATF template or advice on how to create one. We have a previous ATF from LEA, but the duplicated entries would complicate any translation of data between the spreadsheet and a potential new ATF file.
Thanks
