How to format text in a row all at once to be uniform

I am copying and pasting manual standards into a sheet. When pasted, the number reads "-1" and I want to make it be formatted "1." I would like to do this for all rows at the same time.

Easy to remove the dash "-" but not sure about adding the "." so can only half help…

If you're not using the dash elsewhere in the sheet, you could do a find and replace:
Ctrl F
Under Find write -
Don't write anything in Replace With
Press Replace All

Thank you, that worked! Now I just need to figure out how to add the ".".
