I need the content of a windows file (the file is in csv format)

I need the content of a windows file (the file is in csv format) in order to eventually send part of the content to an SQL Server database.

I was able to upload the file into an appian document using Appian RPA. I'm also able to find the documentID of the uploaded document.

I can't find a function/way of converting/loading the content of the document to a map/array.

Is there another way of dealing with this?

Please let me know, thank you.
