Final answer:
The control device that caused the data flood in OE 2007-15 was autofill.
Step-by-step explanation:
The control device that caused the data flood in OE 2007-15 was autofill.
The autofill feature in Office Excel 2007-2015 automatically fills in a series of values or formulas based on a pattern. This can lead to a data flood if the pattern is unintentionally applied to a large range of cells, causing a rapid and excessive increase in the amount of data.
For example, if a user accidentally drags the autofill handle in Excel and copies a value or formula down thousands of rows, it can quickly result in a flood of data that may not be useful or desired.
