Converting data into a monthly calendar format/visual

[Schaak]

Hi all,

I have a long list of numerical values with an associated month / date / day. I would like to convert these figures to view them in a "calendar" visual for easier reading. Is there an easier way to do it to avoid manually entering the data?

I am attaching the spreadsheet where I enter a few fields manually to get a better idea of what i am on about.

Any help would be appreciated.

Thank you!
