Hello,

So I've been trying to manipulate a cell array so that it is in the proper format for the datainsert command I am trying to use. An example would be, that I need something like:

columns = {'Name','Location','ID','Number'};

to be modified to become:

columns = {'[Name]','[Location]','[ID]','[Number]'};

I've tried messing with strjoin and join, but I haven't been able to figure it out. I'm sure it is something easy, I hope someone can provide an answer.

Additionally, my main goal is to create something that can be used for when my cell array contains 1Xn number of strings, as what I am using the master script for can have a different amount of things inside the cell array and I want to be able to add the [] to everything inside of it.

If something isn't clear let me know and I'll try and be more specific.

Thank you,

L

Thanks Jan! Walter posted first though and his answer worked.

You are welcome. I'd prefer strcat, because it is faster. But in many cases the runtime does not matter.
