How to make a program that others can run with minimum fuss for Calc?

I have a D&D group that uses spreadsheets to hold character data; I want to be able to run a program from within the spreadsheet, where we can use data from specific cells as inputs, and it spits out the result into the cell it’s called in.

I’ve got the program working so this works in the command line:

See? Put in 2, 10, 3, and 4, get out 20.

So the question is, what is the simplest way to make it so that I can do something in place of “SomehowCallMyProgram” to actually call the program? Does everyone who would use my program have to set up a Python IDE? Would it be simpler for other users if I wrote the program in BASIC instead python, as it currently is? And also, what do I replace “SomehowCallMyProgram” with to actually call the program?

Code here:

Did you already try opening your existing execl document/s with LO and see if stuff still works?
Best case, you do not have to change anything, if you did not use any “fancy” function/features.

@Fuligina, If you post an example from the file, it would be easier to understand the need. Edit your question and use the clip icon to attach.

I think “minimal fuzz” for everyone of your D&D group would be achieved by porting your “d&” into a macro or formula. But the decision depends a bit on preference and on the complexity of your python script. Could you attach the script so we can estimate how hard it would be to rewrite it as formula/maco?


here is your programm as a BASIC macro. Just put it into Tools → Macros → “Edit Macros” and you can call it from inside any cell via


Here the macro:

Function DIE(uBound As Double)
    DIE=(CInt(1.0 + Rnd() * (uBound - 1.0)))
End Function

Function DCALC(num1 as Integer, num2 as Integer, num3 as Integer, num4 as Integer)
	Randomize() rem init rnd seed with system timer
	Dim damage as Integer	
	damage = 0
	For i = 0 To num1
		damage = damage + DIE(num2)
	damage = damage + (num3*num4)
End Function

Hope that helps.

Have a nice day and let’s (continue to) “Be excellent to each other!”

Thank you, this is awesome! I appreciate the help. Except that when I use it, I just get num3*num4, so I’ll see if I can fix that. Edit: Figured it out, just added a line to DIE: DIE=RndRange

My Bad, i refactored the name and forgot that. I’ll edit it.
