There is a different thread concerning this problem, using some invoked VBA code (How to get the value of checkboxes in excel table - #2 by Nithinkrishna).
I am currently also facing this problem, where a larger number of checkboxes is placed on each row in a specific column (8 checkboxes in one cell). How would I be able to retrieve the data (True/False for each 8 checkboxes), for each row?
Is there anyone who could help me with this?
