Hello
Thanks for your answer. I found a solution today:
let
Source = AzureCostManagement.Tables("Enrollment Number", "xxxxx", 8, []),
usagedetails = Source{[Key="usagedetails"]}[Data],
#"Added Custom" = Table.AddColumn(usagedetails, "Tags JSON", each Text.Combine({"{ ", [Tags], " }"})),
#"Parsed JSON" = Table.TransformColumns(#"Added Custom",{{"Tags JSON", Json.Document}}),
#"Tags JSON développé" = Table.ExpandRecordColumn(#"Parsed JSON", "Tags JSON", {"CMDB", "Contact", "Environment"}, {"Tags JSON.CMDB", "Tags JSON.Contact", "Tags JSON.Environment"})
in
#"Tags JSON développé"

I know (now) what is your request.
what I don't know is
which code, of the many received, did you use?
where does it give you error?
can you show the error screen?
hint:
try the code using a table with few rows, change the contents wich you can't expose and let we know what appens.
