Left of a string

Hello, I have a column in my table array called key_value.

The array contains a string such as '1234567891234|XYZ|9999'.

How do I code for each of these cells extract the first 13 characters?

I have tried key_value(1:13) but this does not work and simply pulls out the first 13 rows of records.

If you are accessing a cell array, you should use curly braces. Check out the examples here
