["BSM110"]
["BSM310"]
["BSM540"]
["LAN121"]
["LAN330"]
["IFE151"]

Was that really necessary to remove the question after 2 years?

Hello, my question had some data that were not supposed to be posted and I was recently noticed about that. I tried to delete my question but unfortunately there is not an option to do so. If there is a way to proceed on deleting this thread kindly let me know.

Thank you so much Stephen for clearing that out. Yes I am aware of the terms of use, that's why I was looking for an alternate to delete this thread entirely eventhough some time has passed by. Nevertheless it was very nice of you to spend your time on reminding me them! I wish you best of luck

A trivial implementation using regexprep:
D = regexprep(C,'[\d"]','');
And tested:
>> C = {'["LAN310"]';'["SHA550"]';'["SHA430"]';'["SHB331"]';'["EDU110"]', ... };
>> D = regexprep(C,'[\d"]','');
>> D{:}
ans = [LAN]
ans = [SHA]
ans = [SHA]
ans = [SHB]
ans = [EDU]
... etc
