Easiest way to convert list into one variable?

[phelix]

The goal is to turn this (.txt file list):

111
222
333

Into this (variable):
111,222,333

The only option I could think of is manually assigning each line to an individual variable using "List processing" and then assigning them into a final variable like:
{var1},{var2},{var3}
The problem with that approach is that there are going to be 500 lines in total...



Is there a simpler way of achieving this?

Another option I guess would be to do, Regex find and replace "\r\n" with ",".
But then how could I important 500 lines from a textfile as a variable into the find and replace box?

Yes, I think there is:

Do not forget to add "," in the field of the custom separator so that the lines in your list to be separated by comma when being placed in your variable.

Ok. This is getting closer.
However, I forgot to add another condition:

The list has like 10,000 entries.
I only want to take 500 at a time.

Can this be done with "Merge list items"?
