Reverse value in a column
 

If I have a column with numbers and there are both positive and negative
numbers and I want to change all positive numbers to negative in one formula.
I know how to change negative into positive.

Reverse value in a column
 

If you want to change +ve to -ve and leave the -ve unchanged, use =-ABS(A1)
If you want to change +ve to -ve and -ve to +ve, use =-A1

Copy the formula down the column.
