Convert key value pair to json javascript

Executing json.getString("key2") will return an empty string.,Executing json.getString("key3") will throw an exception.,Executing json.getString("key1") will return a null.,Getting a Key-value Pair

Hi, I have a json object as input, however one of its elements is a string that contains keys and values.I would like to convert this string to json., How to convert key value string to json in NiFi ,And most important is that we don't know in advance what will be the keys inside the "addition_information" parameter. We have "age" and "height" in one event, but in another event we can get other information.,One of the challanges that I have is that I don't know in advance what are the key names. So in the above example, I don't know in advance that I will get inside the "additional_information" the "age" and "hight" keys. This part is dynamic.

This is the Shell script with awk to convert key value pair into JSON,So here is the quick snippet to converts the key=value pairs into a JSON format,How to convert a key-value pair into JSON.  While there are many ways to programmatically do it. I often find myself doing this type of conversion quite often and I looked out for a simple solution.,I have saved this content into a file named test.env and converting it now to the JSON with the following command

So let us consider a sample key-value data given below.

username = sarav
secret = YouOweMeaBeer
address = virtualspaceovertheweb
website = gritfy.com
about = aspirer[email protected]
skills = ['daydreaming', 'writing', 'music']

This is the Shell script with awk to convert key value pair into JSON

#!/bin/bash

# sarav([email protected])
# convert key = value to json
# Created at Gritfy(Devops Junction)
#

file_name = $1
last_line = $(wc - l < $file_name)
current_line = 0

echo "{"
while read line
do
   current_line = $(($current_line + 1))
if [
   [$current_line - ne $last_line]
];
then
   [-z "$line"] &&
   continue
echo $line | awk - F '='
'{ print " \""$1"\" : \""$2"\","}' | grep - iv '\"#'
else
   echo $line | awk - F '='
'{ print " \""$1"\" : \""$2"\""}' | grep - iv '\"#'
fi
done < $file_name
echo "}"

give executable permission to the script

chmod a + x / tmp / keytojson.sh

Data is enclosed in double quotation marks and the key-value pair is separated by a colon.,There can be more than one key-value pair and each one is separated by a comma:,The example above showed an object, a collection of multiple key-value pairs.,Let's take another example:

In JSON, data is written in key-value pairs, like so:

There can be more than one key-value pair and each one is separated by a comma:

"first_name": "Katie", "last_name": "Rodgers"

Objects are inside curly braces:

{
   "first_name": "Katie",
   "last_name": "Rodgers"
}

A JSON object contains zero, one, or more key-value pairs, also called properties. The object is surrounded by curly braces {}. Every key-value pair is separated by a comma. The order of the key-value pair is irrelevant. ,A key-value pair consists of a key and a value, separated by a colon (:). The key is a string, which identifies the key-value pair. The value can be any of the following data types:

Examples

{} //Empty JSON object

{
   “
   StringProperty”: “StringValue”,
   “NumberProperty”: 10,
   “FloatProperty”: 20.13,
   “BooleanProperty”: true,
   “EmptyProperty”: null
}

{
   “
   NestedObjectProperty”: {
      “
      Name”: “Neste Object”
   },
   “NestedArrayProperty”: [10, 20, true, 40]
}

Sometimes, we want to add a new key value pair in existing JSON object using JavaScript.,In this article, we’ll look at how to add a new key value pair in existing JSON object using JavaScript., No Comments on How to add a new key value pair in existing JSON object using JavaScript? ,To add a new key value pair in existing JSON object using JavaScript, we can parse the JSON string with JSON.parse, then add the key-value pairs we want, and then convert the object back to a JSON string with JSON.stringify.

For instance, we write:

const s = `{
  "workbookInformation": {
    "version": "9.1",
    "source-platform": "win"
  },
  "datasources1": {

  },
  "datasources2": {

  }
}`
const obj = JSON.parse(s)
obj.foo = 'bar'
const newS = JSON.stringify(obj)
console.log(newS)

var jsonPerson = '{"first_name":"billy", "age":23}';
var personObject = JSON.parse(jsonPerson);

The JSON data contains the key-value pair as string values; thus, sometimes the data may in a string format and need to send over API call. The data should be formatted to send the request data from the client to the server, and the response will be mostly in the JSON format, but you can convert the string to JSON using the function stringify(). The basic syntax of the function stringify() is as follows: ,The statement in the above lines of code uses the eval() function followed by the state variable as an argument, this.state.stringData, which converts the data into the specific format.,In the above code lines, the data source is this.state.stringData, a state variable containing an array of objects.,The array of objects is now converted to JSON, and it can be sent over to the server to pass the request as a JSON file format using the stringify() function.
