I am looking for a way to get all Data Item Codes (e.g. TR.VWAPVOLUME) into an Excel spreadsheet. I am aware that the Data Item Browser contains all Data Item Codes. I am looking for a way to consolidate all fields in an excel spreadsheet for programmatic use.
I'm afraid there's no good way of doing this currently. The most you can do is follow Formula Builder wizard in Excel and include the list of fields as cell references for use in =TR function one category of fields at a time.
