Hi all,

Source = Json.Document(Web.Contents("https://xyz-sb1.restlets.api.netsuite.com/app/site/hosting/restlet.nl?script=7&deploy=1", [Headers=[Authorization="NLAuth nlauth_account= , nlauth_email= , nlauth_signature= , nlauth_role = ", Accept="application/json"]])),
#"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Expanded Value" = Table.ExpandRecordColumn(#"Converted to Table", "Value", {"SO_Number", "PO_Date", "Department", "Class", "Location"}, {"SO_Number", "PO_Date", "Department", "Class", "Location"})
in
#"Expanded Value"
