Hi, i have problem with Excel Serializer v3.2.0, I define name of sheet in first step, and when task gets to 3rd step error message occures : Input does not contain column ‘SHEET1’ with sheet names.
you are mixing two connectors. There are two ways how to get data into Excel:
Excel serialiser
Here you have to provide flat data schema with data and configure it based on manual here: Excel serializer - Help center
Second option is to use
JSON to Excel
Here you have to specify special JSON with structure you have on your picture and then send it to JSON to Excel connector: JSON to Excel converter - Help center
