NSIS does not have native JSON support, you are stuck with the plug-in.
If the file is really small and simple you might be able to use the NSIS file and string instructions but I don't really recommend it.

I am sorry for the basic questions. I have this in my json file
{
"BLD_BRH" : "****",
"RLS_STR" : "****",
"RLS_FIXED" :
}
i am setting this nsJSON::Set /file $EXEDIR\manifest.json . but I just need to read BLD_BRH and RLS_FIXED. I don't see anything here in examples

"BLD_BRH" : "****",
"RLS_STR" : "****",
"RLS_FIXED" :
}

I don't want to write anything. there is already a file that I just need to read.

"BLD_BRH" : "****",
"RLS_STR" : "****",
"RLS_DFT" : [

],
],
"RLS_FIXED" :"***",

it shows blank
trailing commas are not allowed in JSON
even without that, no difference. it is the same blank message
There is known bug in this plug-in, it does not support empty arrays.
my actual file is not empty... it looks like i have to use file and string instructions
