What it does: The TRIM() function removes extra spaces from a text string, whether at the beginning, middle, or end. It will also remove extra paragraph breaks (ASCII Character #10) at the beginning and end of a text

Plain English: As you’re cleaning data, you may arrive at cells with extra space characters at the beginning, middle, and end of the cell. For example, this function would change

"  This has been a very  unproductive  week "

to

"This has been a very unproductive week"

Notice the extra spaces eliminated at the beginning, middle, and end of the string.

Arguments: TRIM(text)

Example:

The screenshot above shows the elimination of several extra spaces and a paragraph break at the end of E3.
