Excel 2007 : Sort tabs

On excel tabs at the bottom each has a different name as I work they get moved around. Is there any way to reline them from a to z
Thanks William

yes that is what I do working on them I drag them from one end to the other but at the end of the day I would like to hit a button and the tabs would all go back to where they were you see I have over 250 tabs and I really mess them up thank you looking in vba now hoping to find what I am looking for. you help a great deal
