The relevant data can be run in Notepad++ with Plugins > MIME Tools > Decode Base64, saved as zip and opened with unzip.
The script I’m working with is a shcedule script.
I tried the two methods mentioned to decode in Suite Answers.
1- From base64 to UTF_8 with N/encode module (Returned result is completely wrong for this problem)
2 – The solution in the link: https://netsuite.custhelp.com/app/answers/detail/a_id/41271/kw/base64%20decode
(In this solution, when you save the returned data as zip, it gives an “Unexpected end of the archive” error when opening the zip.)
