I am new to JSON and concepts. I want to extract the data from an API which i have mentioned below, basically i want to extract several details from this API about an Stock. The problem here is, after parsing the URL i dont know how to extract the value for each variablle.
I want to extract the data into an GoogleSheet.
the output of the below function shows, like this
[20-12-10 20:45:15:806 CET] [{symbol=JMIA, price=37.0497, volume=1.317713E7}]
The output i wanted is that:
JMIA
37.0497
1.317713E7
Code :
function CurrentPrice() {
var url = 'https://financialmodelingprep.com/api/v3/quote-short/JMIA?
apikey=7c2f5bcb573b33050c1aad41a54919';
var response = UrlFetchApp.fetch(url);
// convert json string to json object
var jsonSignal = JSON.parse(response);
Logger.log(jsonSignal);
}
I suggest you read this "Working with Objects" article.
The response is wrapped in brackets [] meaning it's an array. I assume you're only expecting one response, so you can grab that first element using jsonSignal[0], which will give you an object.
To get an object property, you have to specify the property name using either dot- or bracket-notation. (I'll use dot-notation.)
const jsonSignal = [{symbol:'JMIA', price:37.0497, volume:1.317713E7}];
console.log(jsonSignal[0].symbol); // 'JMIA'
function CurrentPrice() {
const url = 'https://financialmodelingprep.com/api/v3/quote-short/JMIA?apikey=API_KEY';
const response = UrlFetchApp.fetch(url);
// Convert HTTPResponse
// Use the first element in the response array
const signal = JSON.parse(response)[0];
console.log(signal.symbol); // 'JMIA'
console.log(signal.price); // 37.0497
console.log(signal.volume); // 1.317713E7
}
Try like this :
var json = response.getContentText();
var data = JSON.parse(json);
Logger.log(data);
I read that there : https://developers.google.com/apps-script/guides/services/external

I need to extract data from json response using Javascript. I have checked posts but couldnt find a fitting solution for my problem. The json:
{"apple":{"count":4},"orange":{"messageCount":3},"banana":{"messageCount":2},"grapes":{"messageCount":5}}
I have tried to get the count of each item, eg apple using the below code:
const obj = JSON.parse(txt);
document.getElementById("demo").innerHTML = obj[0];
But returns undefined.
How can i acheive the count of each fruit and store in a variable using Javascript. Thanks
use the JSON.parse() method and store it in the data and get count of each fruit by accessing property of the data object
const response = '{"apple":{"count":4},"orange":{"messageCount":3},"banana":{"messageCount":2},"grapes":{"messageCount":5}}';
const data = JSON.parse(response);
const appleCount = data.apple.count;
const orangeCount = data.orange.messageCount;
const bananaCount = data.banana.messageCount;
const grapesCount = data.grapes.messageCount;
console.log(appleCount);
console.log(orangeCount);
console.log(bananaCount);
console.log(grapesCount);
I have a JSON response like this
const json = '{"arr":[{"key1": "value1"},{"key2": "value2"}], "m":[{"key3": "value3"},{"key4": "value4"}], "b":[{"key5": "value5"},{"key6": "value6"}]}'
I need an array like this
const array = [{"key1": "value1"},{"key2": "value2"},{"key3": "value3"},{"key4": "value4"},{"key5": "value5"},{"key6": "value6"}]
how can I achieve that?
Tough to test with the data you supplied as it is neither valid JSON or valid JS objects. But generally speaking you want to go inside an object and spread all its keys' values. Here is the code to do that:
const json = '{"arr":[{"key1": "value1"},{"key2": "value2"}], "m":[{"key3": "value3"},{"key4": "value4"}], "b":[{"key5": "value5"},{"key6": "value6"}]}'
const obj = JSON.parse(json);
const result = [];
Object.values(obj).map(item => result.push(...item))
console.log(result);
Again, I had to create a valid JSON string for it to work.
Also, please note that this is not a valid JS array: [{1},{2},{3},{4},{5},{6}]
I have a response with two jsons, exactly like this -
{
"redirectUrl": "http:\/\/lumoslocal.heymath.com"
},
{
"status": "SUCCESS"
}
I need to redirect on getting the response to the redirectUrl. Something like window.location.href = response.redirectUrl. But it's not working. Possibly because of two json in my response. How do I use the 'redirectUrl' of my first json?
My understanding (from the OP's comments) is that the response is coming back as a string like this: authResp = '{"redirectUrl":"http:\/\/lumoslocal.heymath.com"}, {"status":"SUCCESS"}'
Technically this is not valid JSON as one big chunk, you'll get an error (test it out below)
JSON.parse('{"redirectUrl":"http:\/\/lumoslocal.heymath.com"}, {"status":"SUCCESS"}')
To successfully parse the data (and ultimately get the redirectUrl data), follow these steps:
split the string with a comma "," character
parse the "first JSON element"
redirect to extracted redirectUrl
Here's the code for each step:
authResp = '{"redirectUrl":"http:\/\/lumoslocal.heymath.com"}, {"status":"SUCCESS"}';
// 1. split the string with a comma character:
let authArr = authResp.split(',');
// 2. parse the first JSON element:
let redirectObj = JSON.parse(authArr[0]);
// 3. redirect to extracted redirectUrl
window.location.href = redirectObj.redirectUrl;
Or, if you want to parse the entire string into an array of JSON objects you can do this:
authResp = '{"redirectUrl":"http:\/\/lumoslocal.heymath.com"}, {"status":"SUCCESS"}';
// create array of json strings, then parse each into separate array elements
authArr = authResp.split(',').map(e => JSON.parse(e));
// Finally, follow #JackBashford's code:
window.location.href = authArr.find(e => e.redirectUrl).redirectUrl;
If your two responses are in an array, it's simple, even if they're unordered:
var myJSON = [{"redirectUrl": "http:\/\/lumoslocal.heymath.com"}, {"status": "SUCCESS"}];
window.location.href = myJSON.find(e => e.redirectURL).redirectURL;
I have the following code to extract values from a JSON response. What I am trying to do is store the data in a similar way to how you would with an associative array in php. Apologies for the code being inefficient. The array comments written down are how I would like it to look in the object.
$.each(responseData, function(k1,v1){
if(k1 == "0"){
$.each(v1, function(k2,v2){
$.each(v2, function(k3, v3){
if(k3 == "val"){
//store in object here
//Array1 = array("time"=>k2, "iVal"=>v3)
console.log(k3 + v3 + k2);
}else{
//Array2 = array("time"=>k2, "aVal"=>v3)
console.log(k3 + v3 + k2);
}
});
});
}
});
So all the information is there but I am not sure how to store each instance for the values in an object. I did try store it like this:
//obj created outside
obj1.date = k2;
obj2.iVal = v3;
But doing this clearly overwrote every time, and only kept the last instance so I am wondering how can I do it so that all values will be stored?
Edit: Added input and output desired.
Input
{"0":{"18.00":{"iVal":85.27,"aVal":0.24},"19.00":{"iVal":85.27,"aVal":0.36},"20.00":{"iVal":0,"aVal":0}}, "success":true}
Desired output
array1 = {"time":"18.00", "iVal":85.27},{"time":"19.00", "iVal":85.27},{"time":"20.00", "iVal":0}
array2 = {"time":"18.00", "aVal":0.24},{"time":"19.00", "aVal":0.36},{"time":"20.00", "aVal":0}
try this :
var g1=[];
var g2=[];
for ( a in o[0])
{
g1.push({time:a , iVal:o[0][a]['iVal']})
g2.push({time:a , aVal:o[0][a]['aVal']})
}

a json response can be converted back to a js object literal by calling JSON.parse(jsonString) inside the success callback of your ajax call.
from then on there is no need for iterating over that object since you navigate it like any other js object which is can be done in two ways either
the js way -> dot notation
var obj = JSON.parse(jsonStirng);
var value = obj.value;
or like a php array
var value = obj["value"];
when saving an array of objects as a JSON, you need to use the following format in Sample.txt to not run into parsing errors:
[{"result":"\"21 inches = 21 inches\"","count":1},{"result":"\"32 inches = 32 inches\"","count":2}]
I'm new to JSON and searching over this for since last 4 days. I tried different approaches of storing an array of objects but no success. My first and simplest try is like this:
function createData() {
//original, single json object
var dataToSave = {
"result": '"' + toLength.innerText +'"',
"count": counter
};
//save into an array:
var dataArray = { [] }; //No idea how to go ahead..
var savedData = JSON.stringify(dataToSave);
writeToFile(filename, savedData); //filename is a text file. Inside file, I want to save each json object with , in between. So It can be parsed easily and correctly.
}
function readData(data) {
var dataToRead = JSON.parse(data);
var message = "Your Saved Conversions : ";
message += dataToRead.result;
document.getElementById("savedOutput1").innerText = message;
}
To make an array from your object, you may do
var dataArray = [dataToSave];
To add other elements after that, you may use
dataArray.push(otherData);
When you read it, as data is an array, you can't simply use data.result. You must get access to the array's items using data[0].result, ... data[i].result...
