CELL is a function in Google Sheets that returns information about a specific cell in a worksheet. The "info_type" argument specifies the type of information that you want to retrieve, such as the address of the cell, its content type, formatting, or protection. The "reference" argument is the reference to the cell that you want to examine.

Here is an example of how to use the CELL function in Google Sheets:

=CELL("address", A1)

This formula will return the address of the cell in row 1 and column A. If you want to retrieve other types of information about the cell, you can change the "info_type" argument. For example:

=CELL("format", A1)

This formula will return the format code of the cell in row 1 and column A, such as "0.00" for a number with two decimal places.
