I'm going to need to see the rest of your code to see if I could even replicate this, I'm 75% sure this isn't a brackets issue. Once again I'm stating that they mean nothing and are just there for visibility reasons so you know you're dealing with a list, meanwhile try the following to find out 100% that its not any of that:
- Use "Replace Text" action with the following regular expression [\[\]"] and replace it with %""% (how PAD reads nulls)
If that works then you were correct, otherwise try the this next regular expression:
- \n+ and replace once again with %""%, also use a "Trim Text" action on the same list.
Also note that these actions will turn your values into variables rather than lists.
Finally if that doesn't work try using excel actions to write into a blank excel sheet and see what is written, if its as you expect then just read from this excel sheet the values you've written, otherwise if they're completely different and have weird symbols in them then its most likely that the text from the .csv file has some special characters that need to be filtered out via the replace action I mentioned earlier.
