@Rodrigo Daruich Alvarez's answer got me in the right direction but the format wasn't quite right. The below worked for me
concat('file',string(utcNow('yyyyMMdd'),'xls')
the formDataValue didn't seem to work.
documentation here

and add expresion:
concat('file',string(formDataValue(utcNow(),'yyyyMMdd')),'xls')
