Maintaining standardized SQL formatting in Visual Studio is essential for team productivity and code sustainability. The IDE’s native SQL support, however, offers only basic formatting options, resulting in variable styles across files, extended code review times, and added complexity during debugging.
Dedicated extensions overcome this constraint by integrating reliable, automated formatting—ensuring consistent indentation, casing, and layout directly in the development environment.
