Regular expression to extract text between square brackets & last string out of the square bracket

I am new to the regex and trying to write the RegEx for the below string.

[1] [2] [3] [] [5[any]] my text

I want something like

1
2
3

5[any]
my text

I have tried the /\[(.*?)\]/g but it not working with inner brackets & the last word outside of the brackets

Try:

((?<=\[)(?:[^\[\]]|\[[^\[\]]+\])*(?=\])|(?<=\s)[\w\h:.,]+$)

See: regex101

Explanation

• ( ... ): capture result to group 1:
  • (?<=\[) ... (?=\]): either in between brackets:
  • (?: ... )*: match 0 or more times:
    • [^\[\]]: either non brackets
  • |: or
    • \[ ... \]: brackets with
    • [^\[\]]+: non-brackets in between
• |: or words at the end:
  • (?<=\s): check that a space is preceeding
  • [\w\h:.,]+: match word characters and horizontal space; here you can add more characters as needed
