How to turn a json string into a properly beautified string to be used in email using a Logic App

Logic App
"Send_an_email_(V2)": {
"inputs": {
"body": {
"Body": "<p><br></p>\n<pre><code>Message 1<br>\n<br>\n#{variables('Message1')}<br>\n<br>\nMessage 2<br>\n<br>\n#{variables('Message2')}</code></pre>\n<pre><code><br>\n<br>\n<br>\n<br>\n</code></pre>",
"Importance": "Normal",
"Subject": "Test",
"To": "test#test.com"
}
This is how it looks like in the email. I know the Message 2 has it already nicely formatted but I would want both to look the same.
Any ideas are appreciated.

After reproducing issue from my side, I got the expected results by taking Parse Json Action after initialize variable action.
As shown in below images i have taken initialize variable actions and send email.
With out parse Json action I got below output in email.
As shown in below image in Parse Json action take Content as Message 1 from dynamic content .
Schema :
{
"Request_Date": "2023-07-18",
"Number_of_Adults": "5",
"Number_of_Children": "1",
"Total_Cost": "690"
}
Then in Send Email action in body take your required data from dynamic content of parse Json 1 as shown in below image.
Then the logic App ran successfully and email got received with expected output format.
Reference MS document for parse Json.

replace(replace(replace(variables('Message1'),',',',<br> '),'{','{<br> '),'}','<br>}')

JavaScript: read and write json file

I have generated json file from my consumer pact in javaScript. When it's generating json file it doesn't contain what I expect. So, now I want to add block to my json file which I don't know how to do? Can someone here help me with that? so, basically I want to read json then create block and then write into json and save data
"path": {
"dataType": "String",
"expression": "data/xml/${id}",
"key": "request"
}
Thanks,

As #Barmar pointed out you can simply parse your JSON text and modify it.
let yourJsonText = "{...}"; // read in your json however you want
let yourJson = JSON.parse(yourJsonText);
// then modify your object
yourJson.path.newAttr = "something you like";
// parse it back to a JSON string
let yourUpdatedJsonText = JSON.stringify(yourJson);

Reading JSON data from JS file

I am uploading one JS file using HTML input file tag. I am reading the data in Python. Since in my data var acb_messages is written, I am not able to parse it. And I want to use this variable name to get the data so I can remove it.
var acb_messages = {"messages": [{
"timestamp": 1475565742761,
"datetime": "2016-10-04 12:52:22 GMT+05:30",
"number": "VM-449700",
"id": 1276,
"text": "Some text here",
"mms": false,
"sender": false
}
]}
How can I parse it in Python and then how can I use it?

Two approaches that I would try if I were at your place -
Convert my .js file to .json file and then using method suggested by #Sandeep Lade.
Reading .js file as string, cropping out the value part and then using json.loads(<cropped part>) as suggested by #rahul mr.
Here is how to achieve 2nd solution -
import json
with open('your_js_file.js') as dataFile:
data = dataFile.read()
obj = data[data.find('{') : data.rfind('}')+1]
jsonObj = json.loads(obj)
What's happening here is that you are finding first reading your .js file (that contains js object that needs to be converted into json) as string, find first occurence of { and last occurence of }, crop that part of string, load it as json.
Hope this is what you are looking for.
Warning - Code works only if your js file contains js object only.

The options above are correct, but the JSON syntax in JS can be a little different than in Python:
example.js:
property.docs = {
messages: {
timestamp: 1475565742761,
datetime: "2016-10-04 12:52:22 GMT+05:30",
number: "VM-449700",
id: 1276,
text: "Some text here",
mms: false,
sender: false
}
};
Therefore we need one more tweak that I found at: How to convert raw javascript object to python dictionary?
The complete code should be:
import json
import demjson
with open('example.js') as dataFile:
data = dataFile.read()
json_out = data[data.find('{'): data.rfind('}')+1]
json_decode = demjson.decode(json_out)
print(json_decode)

import json
jsonfile=open("/path/to/json file")
data=json.load(jsonfile)
the above code will store will store your json data in a dictionary called data. You can then process the dictionary

JSON parsing and stringify

I am currently working on a Javascript project where I have to parse tons of data. The project requires that I parse some JSON data and bring specific data into another array. Right now, I am using the JSON.stringify method and I can console.log all of the data that I need. The data looks something like this:
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Polygon",
"coordinates": [
[
[
-85.3865810000125,
33.90171899971196
],
[
-85.38659500025622,
33.9017919996593
],
yes, this is not all that data-it is about 1200 pages long! I only pasted in the top segment of it. All I really need is how to get to the coordinates aspect of it and into an array. So what I am currently doing is this:
var work = JSON.stringify(response, null, 4)
console.log(work);
Which gives me the above response. However, I am not that familiar with JSON.stringify so if I do:
console.log(work.type);
Attempting to see what the value is for type, I get a response of undefined. Now if I try doing this:
var work = JSON.parse(response)
console.log(work);
I get a response of: VM296:1 Uncaught SyntaxError: Unexpected token o in JSON at position 1
Thus, I cannot get the data parsed which I want to get to which will be the coordinates data. Any help with using stringify would great help me. I have read a lot about how it turns the data into a string but have not really seen a lot about how to parse it. Do I have to use parse? Thank you for your help!

You dont' have to use stringify or parse for this. The response object you are receiving is already a javascript object so you can reference its properties normally
response.type; // => "FeatureCollection"
If you try and stringify the response it will lose its type property, for instance:
typeof "some string".someProperty; // => undefined

Unexpected token ILLEGAL : how to remove &quote; and lines breaks from JSON

I receive a jsonfrom the server when loading a page, and it gets populated in the page using Handelbars.java. Till now everything's fine.
However I would like to get that jsonobject and store it on a javascriptobject this is where I fail.
When I try to store it on a javascript object I do the following :
var jsObject = "{{output.items}}"; // the output.items is the JSON retrieved on the template
I get the following (&quote; and line breaks interpreted) :
{
"profile": {
"name": "copernic",
"email": "copernic#cop.com"
}
....
}
When I should get the following (without line breaks interpreted) :
{
"profile": {
"name": "copernic",
"email": "copernic#cop.com"
}
....
}
So it throws me an error on javascriptUncaught SyntaxError: Unexpected token ILLEGAL.
When printing the json on the HTML template using <pre>{{output}}</pre> it looks just fine.
Do you have any idea about how can I store the jsonreturned from the server on page loading on a javascriptobject as I don't have much control of it since it's NOT coming with json?
Thank you.

Your server is serving a incorrect json format.
Your server needs to serve a json string, with double quotes.
{
"profile": {
"name": "copernic",
"email": "copernic#cop.com"
}
}
If you need to serve a well-formed json, you can try with Gson.

Since the content output.items ist a string, this is how you can proceed.
eval("jsObject={" + object.items.replace(/"/g,'"')+"}");
