Perhaps I should just loop through each line checking if it 'contains' one
of the codes instead?
I would do that.
Regex is handy at times, but it's a complex subsystem and notoriously
slow with complex operators.
I'll bet if you can first run a filter against the left-most column, a
"repeat for each" on the remainder would likely be about as fast as you
can get.
Sometimes "repeat for each" on the whole thing is faster than "filter".
