Hi! :)
In one of my apps I am using writetable function and my problem seems to be that each time I run the app, the data in the table ( heterogenous table) that is written, is not overwritten.
Can somebody help me with my problem?

Even then, without seeing the code it is not possible to suggest how to solve the issue/problem.

I'd say sure, but upgrade to R2023b, the latest, instead of R2020a. Can't hurt. Otherwise call delete(filename) before calling writetable to make sure the file has only the new data in it.

Well you asked about upgrading...but no, it should not be necessary. You did delete the file like I suggested before writing it again, right? If so, then if in the new file the character data is not written out with writetable then that means that the character data was not present in the table. Check all the columns of the table just before you call writetable.
