Hi Elshan. I am an Excel user like you.
You can do this by entering two formulas as Conditional Formatting rules. This one will give you the rule for absolute value less than or equal to 5% formatted green:
=ABS($B2)<=5%
Make another rule with this formula and format Red:
=ABS($B2)>5%
Highlight all cells/columns you want colored with the conditional formatting before entering each rule.
