The sdy file extension is associated with StarMoney, German personal finance management software developed and sold by Star Finanz GmbH for Microsoft Windows.
An sdy file stores financial data for use within StarMoney. It is part of the application's proprietary data handling and is not intended to be edited as a plain-text document.
Open an sdy file with StarMoney on Microsoft Windows. Use StarMoney's own commands to open, restore, or import the file, depending on how it was obtained and on the installed version.
Because the format is proprietary, general-purpose spreadsheet and text applications are not suitable for opening it.
Open the sdy file in StarMoney and use the program's export function if the financial data needs to be transferred to another application.
