Searching text file in Unix using shell script

Question

I have an input text file (shown below) which I have to call in a shell script and also in shell script I will pass an input argument for which I have find a corresponding value from the input text file.

So if my input argument is Janan I have to return Janan_2 as output, or if my input is Janan_ex1 then output will be Janan_loc_data .

Input:

"data":"{\"collection\":{\n    \"Janan\":\"Janan_2\",\n    \"Janan_ex1\":\"Janan_loc_data\",\n    \"Neha\":\"Neha_1\",\n    \"cric\":\"cric_2\",\n    \"San\":\"San_1\",\n    \"Arp\":\"Arp_1\",\n    \"Nipun_test4\":\"Nipun_test3\",\n    \"tran_Nipun\":\"tran_Nipun_2\",\n    \"Zing\":\"Zing_1\"}}"}

Pipe your input "file" into the following bash script with your "input argument" as the argument, eg ...|./bashscript San :

#!/usr/bin/bash

sed 's/[^ ]*// ; s/}}"}// ; s/"://g ; s/,\\n/\n/g'|
tr -d '\\'|
awk -F\" '$2=="'$1'"{print $3}'
