# How to transfer symbolic expression to code? [closed]

I have a lot of messy things in Mathematica in a form like this:

Mathematica perfectly solves all these symbolic equations. But I'm in trouble when using Excel link with Mathematica. I really need to use Mathematica-defined symbolic formulas in Excel, so how can I transform from symbolic language to code?

• There is no difference between what you call symbolic language" and what you call "code" in Mathematica, so it is not clear what you are asking for. Could you elaborate on what you mean by "code"? – m_goldberg Mar 11 '16 at 20:27

You could also, in the long run, try to use the defined functions in Mathematica for the symbols to begin with. In my experience, this is a more robust method. For example, the you posted can be represented with the Sum function. Putting the symbols into Mathematica's Wolfram Documentation (available in the Help menu), will give you how Mathematica interprets these symbols. For example, searching the summation symbol yields the information at the following link: https://reference.wolfram.com/language/ref/character/Sum.html
