Method range of object _worksheet failed is a technical term used to describe an error that occurs when a program tries to access a property or method of an object that does not exist. This can happen for a number of reasons, such as:
- The object has not been properly initialized.
- The property or method does not exist on the object.
- The object is of a different type than the one expected.
When this error occurs, it is important to debug the code to determine the cause of the error and fix it. Otherwise, the program will not be able to continue running.
