How do I add +1 digit to numbers in one cell ?

How do I add +1 digit to numbers in one cell (word or excell or notepad, doesn't matter). But at My work I often have: 14,17,28,31,35,38,50,53,70,73,80,83,90,93,120,123,135,138,150,153,165,168,180,183,210,213,250,253,275,278,300,303 something like that.

And I need to make them like: 15,18,29,32,36,39,51,54,71,74,81,84,91,94,121,124,136,139,151,154,166,169,181,184,211,214,251,254,276,279,301,304. I do it manually, but maybe there is a fast way to do it?
