Convert the byte array data in the given encoding to a string type using
ByteArrayToString(body, 'UTF-16LE').Split the data from step 2 using
STRSPLITTOBAG(body,'\n') and then a Flatten() to get individual records or lines.Remove headers as applicable (if it is from an API) with the filter transformation. Text matches(regex) options can be useful here.
Individual lines are split based on the relevant delimiter using
CSVSPLIT(line, '\t').
