31 Some attachment types, such as Excel and PowerPoint, need a conversion step that runs inside the sandbox. Enabling **Advanced file analysis in Chat** under **Product availability** on the [Config](/docs/government/config/settings#product-availability) page lets Claude run code against attachments in an offline sandbox, including that conversion. You do not need to make Cowork available to get this capability. See [Chat in Claude Desktop](/docs/third-party/claude-desktop/chat) for how Chat handles file attachments.
