Good day. Sorry, I am using an online translator.
How to write to file, json response ?
01

It turns out like this.
02

I need it this way.
03

You need to first join the list using a Join List block so it becomes a string, then you can write the string like you are doing now

Does not work.

04

edit this line

list = $["<TAB>"]

and put it like this

list = @TAB

You should learn when to use variable mode instead of interpolated mode!

Thank you very much, everything worked out.
