When you get an error message, start with reading the documentation:
doc csvread
There you find:
The file must contain only numeric values.
This mean clearly, that you cannot import your file using csvread because: 'Column "AA" is string'. Use textread or readtable instead.
Note: You are a long term user of this forum. It does not look efficient, if it is still required to suggest reading the documentation.
