Comparing data in two json files, and get the unmatched values and also their count

I have two text files with some data as below,
First text file contains below data.
{
"Employment Based non immigrant visa ": [ {
“visa classification”: " "
}
],
“Temporary need information”: [
{
“Job title”: “Software developer”,
}
],
============= Second Text file contains data as below=========
{
"Employment Based non immigrant visa ": [ {
“visa classification”: “H-1b”
}
],
“Temporary need information”: [
{
“Job title”: “Submitted2”,
}
],
SO each text file have different data so i have to compare the data in two files, if there is any unmatched data the bot need to get the unmatched values and also unmatched value count…
for example:
there is a “visa classification”: " " in first file and “visa classification”: “H-1B” in Second file, so the bot should bring the “visa classification” into excel and also the total unmatched count value is 1(Visa Classification).

Can someone help me on these how to overcome to get the unmatched content.

Kindly note that the text is JSON Data.
