Import Excel file with calculations in Joomla website

Hi there,

We have been using Dropfiles on our Joomla website and we are pretty happy with it.
We have a tax calculator built into an Excel file, is Droptables capable of importing all calculations/formulas that is being used?


I could not attach the Excel file (error:"The file Property Tax Calculator (main).xlsm, which you are attempting to upload is in an unsupported format."
Here's the dropbox link:
https://www.dropbox.com/s/4bqbgmxkoaekda6/Property%20Tax%20Calculator%20%28main%29.xlsm?dl=0

To get better understanding, open the Excel file and follow these steps:

Once the file is opened, select Property Tax Calculator sheet and click on Residential button (just for example)
Select any County District / Location from the dropdown menu
Enter the property value (e.g. 300000) in the field next to Residential and hit calculate
The result in table/chart will display

Thank you in advance.

Best,
Madhav
