Please help.

I have a large excel sheet with the columns looking as follows:

A B C D
E

207,803, 209 9 44,946, 2527,571, 296900,873, 291158,381,
210,000, 209 12 44,228, 2527,571, 296899,802, 291156,463,
214,643, 209 19 3,160, 2527,571, 296897,532, 291152,412,
216,818, 209 22 0,637, 2527,571, 296896,466, 291150,516,

What I need to do is make the columns do look like the following but without
have to go to each cell to edit the contents, i.e putting +signs in column A
before last 3digits, putting decimal place in front of the last 3digits in
column B, C, D & E and removing the commas throughout.

There a thousands of these figures that will be inputted on an ongoing basis
so I need to customize each column so only figures need to be inputted and
not various symbols.
