Which of the following is NOT a valid output of a Write Range activity?

The validity of outputs from a Write Range activity revolves around the function's ability to write data into specified locations within workbooks or similar structures.

Creating a new workbook is a logical output of the Write Range activity, as this activity can initiate a workbook if it doesn't already exist, and then proceed to write data into it. Similarly, appending data to an existing workbook is a core function of the Write Range activity where it can take new data and add it to any specified range in the existing workbook without overwriting the current contents if directed to a non-overlapping area.

Writing data into a nonexistent file is a bit nuanced; while technically the file should exist before an attempt to write, the operation itself can trigger the creation of the file if it doesn't, allowing data to be written.

On the other hand, deleting existing data is not an output of a Write Range activity. This activity is primarily designed for writing new data rather than removing or altering existing data directly - it does not have a function that allows for the deletion of what is already present in the workbook. In the context of the current question, deleting data would require a different approach or activity specifically designed for manipulating existing data rather than writing new data, making it the correct answer in
