Calculate text formula

[Gerard_Jimenez]

Hi all, have been looking all the options for this scenario but haven't found any solution, or at least I have not been able to understand them.

I have a formula set that I wish to calculate, where x should be replaced by a value, let's say 10, and calculated as per this example:

Formula	Result
1	1
2	2
x	10
x+2	12
2x+1	21
3x+5	35
10x+20	120

Any help would be greatly appreciated.

Perhaps like in the attached workbook?

Hi, thanks for your prompt solution, but that wouldn't help as it is more of a manual formula.

To further elaborate, I have 1,750 lines, so typing a formula for each line is not a practical solution, on the other hand, if some formulas change, the result should be recalculated accordingly.

I need something more like:

=(value_before_X)*("convert_x_to_value",10,)+(number)

If no value before X, assume 1, if no X at all, use only number after +.

@Gerard_Jimenez Then you'd need som VBA coding. A small user defined function that I called TxtForm. It takes a text string that looks like a formula and "translates" it into a real formula. See attached.

I left the helper columns in there so that you can see how the text string in column E is constructed.

That did it.

I just needed to modify it a bit, in cases where there's no X, just the number. So I modified the helper columns like this:

Column D: =IF(ISNUMBER(FIND("x",C11)),FIND("x",C11),0)

Columen E: =IF(D11=0,C11,(IF(D11=2,LEFT(C11)&$B$1,LEFT(C11,D11-1)&"*"&$B$1)&RIGHT(C11,LEN(C11)-D11)))

I guess it's not the most elegant solution, but I'm not an expert like you.

Thanks a lot for your help.

@Gerard_Jimenez Elegance doesn't really matter. Like beauty, it's in the eye of the beholder. All that matters is that you succeeded to adopt my formulae by yourself and that it works for you.
