# Excel DDE

"Operating Without a DDE Socket" section has been removed from documentation. Interactive Brokers no longer supports connecting TWS to the Excel DDE offering without the use of the intermediary Java DDE Socket Bridge. This also means that the LegacyDDE request structure is now deprecated. Customers should review the DDE Socket Bridge section to better understand how to run and operate the DDE Socket Bridge.
