CSE functions (aka array formulas) in Excel are functions that apply across a range of cells to aggregate the result in once cell.
CSE functions are applied when a function is entered into the cell, and instead of leaving the cell pressing the enter key, it is left by pressing ctrl-shift-enter (hence the CSE name).
The functions are useful for generating lists of values in a single cell.
For example, a CSE function could be used to generate a semicolon separated list of email addresses based on a column of email addresses and a second column that is used as the filter.
This table contains the 4 bottom rows of data. Entering the formula <code>CONCAT(IF(B$2:B$5>"",A$1:A$5 & "; ","")) </code> into the top right cell and then clicking ctrl-shift-enter will populate the cell as seen here.
