This document discusses information formulae in Excel. It explains that information functions provide details about the data in a cell or range, such as whether it is a number, text, or empty. Some common information functions are ISBLANK(), ISERR(), ISERROR(), ISLOGICAL(), ISNA(), ISNONTEXT(), ISNUMBER(), ISREF(), and ISTEXT(). The ISBLANK() function specifically is highlighted, which returns TRUE if the referenced cell is blank. An example is provided showing ISBLANK() returning False for a non-empty cell and True for an empty cell. The document encourages the reader to learn more about these functions in upcoming presentations.

Why Information Formulae ?
Excel's Information functions gives you information
about the data in a cell or range of cells. This
information includes whether the data is a number,
the formatting applied to the cell, or even if the cell is
empty.
Each of these functions, referred to collectively as the
IS functions, checks the type of and returns TRUE or
FALSE depending on the outcome. For example, the
ISBLANK function returns the logical TRUE if is a
reference to an empty cell; otherwise it returns FALSE.
