# What is a MS Excel Token
This is a Microsoft Excel document that will alert you whenever it is opened in Microsoft Office on Windows or MAC OS.
This is useful for dropping into shares that shouldn't be accessed. Create a juicy filename (employee_salaries.xlsx, passwords.xlsx), leave it lying around on a network share, on a web server, in an email, and wait for the alert to tell you there's someone snooping around.
