What version of Postgres are you using? In this case it probably does not matter that much, but json/jsonb has changed a good deal over recent versions so it is nice to know what you are working with. -- Adrian Klaver adrian.klaver@aklaver.com

A quick and dirty method:
aklaver@test=> create table json_test(id integer, json_fld jsonb);
CREATE TABLE
aklaver@test=> \e sample.json
\e opens an editor. Inside editor add INSERT statement to file:
INSERT INTO json_test VALUES(1, '
{ "glossary": { "title": "example glossary", "GlossDiv": { "title": "S",
"GlossList":{ "GlossEntry": { "ID": "SGML", "SortAs": "SGML",
"GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML",
"Abbrev": "ISO 8879:1986", "GlossDef": { "para": "A meta-markup language,
usedto create
markup languages such as DocBook.", "GlossSeeAlso": ["GML", "XML"] },
"GlossSee": "markup" } } } }
}');
aklaver@test=> \x
Expanded display is on.
aklaver@test=> select * from json_test;
-[ RECORD 1
]-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

json_fld | {"glossary": {"title": "example glossary", "GlossDiv":

Otherwise you will need to find a way to pass the file in from the
shell. You are using Windows it seems and I am not familiar enough with
it to offer any guidance on that topic.

I'd suggest dollar-quoting if going this route - the possibility of the json containing single quotes is significantly large to warrant it.
[...] VALUES(1,$$json$
{...}
$json$);
In Linux we'd do:
(backticks used below)
\set json_var `cat json_file.txt`
INSERT INTO tbl (json_col) VALUES (:'json_var');
Not sure about Windows though.

I am trying to insert directly into table using pgAdmin tool.
I came across something like this
create temporary table temp_json (values jsonb) on commit drop;
copy temp_json from 'C:\Users\\conceptmaps.json';
insert into jsontest ('food') from ---*
//
sp copy seeme to have copied the contents from conceptmaps.json ( from message displayed)
now how to store that content into column 'food'
