Hi Ricardo,
I see you are facing errors while modifying excel files that have AIP labels using the "writetable" function.
I suggest you to use COM server functionality provided by MATLAB to make modifications to files for this requirement. You can use the "actxserver" function to create a COM server and use it to read and modify your excel files. These functions provide you much more customizations and settings while reading and writing to Microsoft documents.
Refer to the following documentation to learn more about "actxserver":
Refer to the following documentation demonstrating, reading and writing to excel files using the server:
Refer to the following MATLAB answer that has example code to modify the AIP tags as well:
Hope this Helps!
