There is only one file type that uses the .WORKSHEET extension:
BBEdit Shell Worksheet File
Developer file created by BBEdit, a Mac OS X source code development program; stores an interactive programmer worksheet, which can save source code text as well as execute commands in-line while editing; used for adding Unix command line features to source code development.
The BBEdit shell worksheet component is similar to the older Macintosh Programmer's Workbench (MPW).
