M-C simulation in Excel (and pref also in Google sheets)

详细信息

I have an @Risk model (runs under Excel) to simulate results for basic property developments. 5-7 key variables. Triangulations and Lognormal distributions in the main. I'd like my model updated and improved (mainly ease of use and to look more professional) and able to run without using @Risk; ideally also in Google Sheets if possible.
