Is there anyway to do the reverse of =FORMULATEXT?

Try this UDF . It works.
UDF code

Function ConToFormula(Ip As String)
ConToFormula = Evaluate(Replace(Ip, """", ""))
End Function

How to Use UDF code:
In the developer tab click--> Visual Basic
VB window opens
Insert--> Module
Paste the code.
Close the VB window.
Now UDF is available in Function List
