numbers are read as text

[Nadja Kelm]

Hi! Thank you very much for the tool!

I have a problem with my data: in the table there are three columns of numbers (no commas, integers) and I cheeked their format in google sheet, they are numbers. But after importing only one column is read as numbers and other two as text? so I cant use them to change width or height of the circles.

I attached the file and would be very appreciate if you can help me to fix this problem
Thank you!
