I'm pretty late to the party on this, but in order to edit (at least if you're doing this on mobile), all you have to do is go to the link, click on Share & Export, and then Save As to save the table as an Excel file. This let me open and edit the file in Google Docs with no issues at all 👍🏻
The level 1 Beastiary building has 977.5 attack and defense stats rather then 997. My in game stats were 2cs off from the calculator and after some troubleshooting I traced it back to the four level 1 Beastiaries I have. Replacing the 997 with 997.5 in the calculator fixed the issue.
Column O208:264 for FS and Pallumen - defensive buildings dont have spy atk U315 - Osmon lvl 16 spy building has 26,000 troops, not 2600
