Convert Excel formulas containing functions to a simple form

Hello Everyone,

I am a beginner with VBA. I want write a macro to convert a formula which contains functions to a simple form. e.g. D12+SUM(E22:E26) should be converted to D12+E22-E26 or D12+SUM(E22:E26)-SUM(F12:F15)-D20+SUM(G12:G14) should be converted to D12+E22+E23+E24+E25+E26-F12+F13+F14+F15-D20+G12+G13+G14.

I have been trying a lot but no success......Can someone please help me out.......or if someone has already done such sort of thing?

Any help would be highly appreciated.

Thanks
