If you are following the steps I explained above (Serialize as CSV - #2 by Gugi), you should add the headers, comma-separated, as the first line (string) of the array.
{
"data": [
"id,name,org",
"1,foo,example",
"2,bar,example",
"3,baz,example"
]
}
You can set up the comma-separated header in a separate array and merge it with the data using Operator Transformer → Array Merge, such as below.
