Add common prefix to all cells in Excel

Question

I have a column with some text in each cell.
I want to add some text, for example \"X\", at the start of all cells. For example:

A             B
-----  &         


        

Answer 1

Select the cell you want,

Go To Format Cells (or CTRL+1),

Select the "custom" Tab, enter your required format like : "X"#

use a space if needed.

for example, I needed to insert the word "Hours" beside my numbers and used this format : # "hours"
