将 CSV 数据复制到 JSON 数组 object 中的 Z3A580F142203677F153F0BC30898FZF 工厂数据

Question

I've been going round in circles trying to get what I thought would be a relatively trivial pipeline working in Azure Data Factory. I have a CSV file with a schema like this:

Id, Name, Color
1, Apple, Green
2, Lemon, Yellow

I need to transform the CSV into a JSON file that looks like this:

{"fruits":[{"Id":"1","Name":"Apple","Color":"Green"},{"Id":"2","Name":"Lemon","Color":"Yellow"}]

I can't find a simple example that helps me understand how to do this in ADF. I've tried a Copy activity, and a data flow, but the furthest I've got is a json object like this:

{"fruits":{"Id":"1","Name":"Apple","Color":"Green"}}
{"fruits":{"Id":"2","Name":"Lemon","Color":"Yellow"}}

Surely this is simple to achieve. I'd be very grateful if anyone has any suggestions. Thanks!

https://docs.microsoft.com/en-us/azure/data-factory/copy-activity-schema-and-type-mapping#tabularhierarchical-source-to-hierarchical-sink

"When copying data from tabular source to hierarchical sink, writing to array inside object is not supported"

But, if we put file pattern under Sink properties as 'Array of Objects', you can achieve somewhere till here:

    [{"Id":"1","Name":" Apple","Color":" Green"}
     ,{"Id":"2","Name":" Lemon","Color":" Yellow"}
    ]
