You can use the following basic syntax to reverse a text string in Google Sheets:
=JOIN("",ArrayFormula(MID(A2,LEN(A2)-SEQUENCE(1,LEN(A2))+1,1)))
This particular formula will reverse the text string located in cell A2.
The following example shows how to use this formula in practice.
Example: Reverse a Text String in Google Sheets
Suppose we have the following list of text strings in Google Sheets:
We can type the following formula into cell B2 to reverse the text string in cell A2:
=JOIN("",ArrayFormula(MID(A2,LEN(A2)-SEQUENCE(1,LEN(A2))+1,1)))
The following screenshot shows how to use this formula in practice:
Notice that the first text string of Elephant has been reversed to tnahpelE.
We can then drag and fill this formula down to each remaining cell in column B:
Notice that column B contains the exact reverse of each text string in column A.
Also notice that this formula is able to handle text strings with multiple words and spaces.
