I have a JSON string in this format:
[
{
"Origin":{
"FtpHost":"info",
"FtpFolder":"info",
"FtpUser":"info",
"FtpPassword":"info",
"FtpInsideFolder":"info",
"Pattern":"info"
},
"Destination":{
"FtpHost":"info",
"FtpFolder":"info",
"FtpUser":"info",
"FtpPassword":"info",
"FtpInsideFolder":"info"
},
"CustomFolderName":"Conad",
"OperationTraverseType":"RootOnly"
}
]
To pick up the JSON I wrote this in Node.js:
var fs = require('fs');
var obj = fs.readFileSync('Operations.json', 'utf8');
I'm wondering, how I can access for example : "Destination" fields?
You must parse this to JSON. because fs.readFile returns string
var fs = require('fs');
var obj = fs.readFileSync('Operations.json', 'utf8');
obj = JSON.parse(obj)
var Destination = obj[0].Destination
// or
var Destination = obj[0]["Destination"]
Edit (as said Diego)
You can also directly require json file
var obj = require('somejsonfile.json');
var Destination = obj[0]. Destination
Just need to simply parse the read data. Something like this:
var fs = require('fs');
var obj = fs.readFileSync('Operations.json', 'utf8').toString();
obj = JSON.parse(obj)
console.log(obj[0].Destination)
you can do like var myjson = JSON.parse(obj) or obj = JSON.parse(fs.readFileSync('Operations.json', 'utf8')) and then access it like obj[0]["Destination"]["FIELD"] where FIELD - represents the "Destination" object field you want

I'm trying to import JSON via API into Google sheets but get the error
Cannot read property 'length' of undefined
Here is my code
function importRank(){
url = 'https://public-api.solscan.io/token/holders?tokenAddress=sinjBMHhAuvywW3o87uXHswuRXb3c7TfqgAdocedtDj&offset=0&limit=max'
var json = JSON.parse(UrlFetchApp.fetch(url).getContentText())
var data = json.data.owner
var data2 = json.data.rank
var data3 = json.data.total
var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('WalletRank')
sh.getRange(2,1,data.length,data[0].length).setValues(data)
sh.getRange(2,2,data2.length,data2[0].length).setValues(data2)
sh.getRange(2,3,data3.length,data3[0].length).setValues(data3)
}
Try
function importRank(){
url = 'https://public-api.solscan.io/token/holders?tokenAddress=sinjBMHhAuvywW3o87uXHswuRXb3c7TfqgAdocedtDj&offset=0&limit=max'
var json = JSON.parse(UrlFetchApp.fetch(url).getContentText())
var data=[]
Logger.log(json.total)
json.data.forEach(function(x){
data.push([x.owner,x.rank,x.amount])
})
var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('WalletRank')
sh.getRange(2,1,data.length,data[0].length).setValues(data)
sh.getRange(2,4).setValue(json.total)
}
Explanation
the structure is as follows
{"data":[
{"address":"__________","amount":________,"decimals":__,"owner":"___","rank":_},
...
],"total":_____}
that means that data is an array [] of multi elements which contains each of them {} address, amount, decimals, owner and rank

forEach
This is the json response (from my multiple choice field jsfiddle) that i'm trying to parse:
{"selected":true,"disabled":false,"text":"Ctr","id":"Ctr","title":"","_resultId":"select2-selectcountry-result-je97-Ctr","element":{}},
{"selected":true,"disabled":false,"text":"Title
Part1","id":"TitlePart1","title":"","_resultId":"select2-selectcountry-result-uv7s-TitlePart1","element":{}},
{"selected":false,"disabled":false,"text":"Milan","id":"Milan","_resultId":"select2-selectcountry-result-bmba-Milan","element":{}}]
I need to get: {"id":value},{"id":value},{"id":value} ...
{id:Ctr},{"id":"TitlePart1"},{"id":"Milan} ...
To achieve this result, I'm using this code:
var response = (JSON.stringify($('#selectcountry').select2('data')) );
var json = JSON.parse(response);
var dataSet = json;
var row = [],
data;
for(var i in json){
data = dataSet[i];
row.push({'id': json[i].id})
}
sheet.getRange(6,1).setValue(row);
But in this way I get only the first id:value:
{id:Ctr}
Any help?
Thanks
var s='[{"selected":true,"disabled":false,"text":"Ctr","id":"Ctr","title":"","_resultId":"select2-selectcountry-result-je97-Ctr","element":{}},{"selected":true,"disabled":false,"text":"Title Part1","id":"TitlePart1","title":"","_resultId":"select2-selectcountry-result-uv7s-TitlePart1","element":{}},{"selected":false,"disabled":false,"text":"Milan","id":"Milan","_resultId":"select2-selectcountry-result-bmba-Milan","element":{}}]';
function findId() {
var d=JSON.parse(s);
var ids=[];
d.forEach(function(o){
ids.push(o.id);
});
Logger.log(ids);
//Add this
SpreadsheetApp.getActiveSheet().getRange(1,1,1,3).setValues([ids]);
}
I want to extract the data from csv file, for that I am using csvtojson npm , it is working fine but if the csv file contains any foregin letters then it return "��" in my json so can anyone guide me here
var converter = require("csvtojson");
function(req, data){
var array = [];
var json = await convert().fromFile(filepath.csv);
array.push(json)
// continuation of my code here
}
try this
var converter = require("csvtojson");
var json = await convert().fromFile(filepath.csv,{ encoding: 'binary' });
I trying to get all keys and use them to access values of that keys, depends of user...
i have this code:
var fs = require('fs');
var _ = require('underscore');
var obj = JSON.parse(fs.readFileSync('ENG.json', 'utf8'));
var lang = process.argv.slice(2);
var keys = _.keys(obj);
console.log(obj.keys[0].text1);
Help me please.
You mean this way?
keys.forEach(key => {
console.log(obj[key]);
});
By the way, no need for underscore. Use Object.keys(obj).
And you can easily require your json this way:
// most probably './ENG.json';
const obj = require('ENG.json');
I am trying to render a jade with some dynamic content. I am reading from a json in jade.
My json looks like this
{ data1: 'data1',
data2: 'data2',
data3:
[ { name: 'ABC',
address: 'India'
},
{ name: 'DEF',
address: 'Australia'
}]}
I am trying to render a jade and use the data from above json
my jade looks like
var data1 = #{data1};
var data2 = #{data2};
var size = #{data3.length};
for data in #{data3}
var name = data.name;
var address = data.address;
I am able to correctly extract data in the first 3 lines mentioned above. But when I try to fetch data from within a loop, I get "Uncaught SyntaXError, Unexpected Identifier" error while debugging.
If i put a line outisde the for loop, it works fine. Ex
var name = #{data3[0].name};
is rendered properly. But i need to iterate over a loop and fetch data over there. Can somebody help.
Thanks
Updating with more information
1. I have node server running where I create a json -
var json_string = "{"data1":"data1","data2":"data2","data3":[{"name":"ABC","address":"India"},{"name":"DEF","address":"Australia"}]};";
var json_data = JSON.parse(json_string);
console.log(json_data);
res.render('sample_example', json_data);
In my sample_example.jade I have the following snippet within script
var data1 = #{data1};
var data2 = #{data2};
var size = #{data3.length};
for data in #{data3}
var name = data.name;
var address = data.address;
As stated earlier, I am able to properly extract #{data1}, #{data2}, #{data3.length} to the variables . But it breaks within the for loop. In fact, I am able to extract #{data3[0].name} from outside the for loop. But within the for looop it gives the stated error.
This is how you can do it now.
In your server-side you have to JSON.stringify the array of objects.
var json_data = JSON.parse(json_string);
// Convert back to json only the property data3
json_data.data3 = JSON.stringify(json_data.data3);
res.render('simple', json_data);
Or the better is to not parse the JSON just let it go the way it is:
// var json_data = JSON.parse(json_string);
res.render('simple', {
json_data: json_string
});
And in the Jade Template (If you followed the better method):
script(type='text/javascript').
var json_data = !{json_data};
var data1 = json_data.data1;
var data2 = json_data.data2;
var data3 = json_data.data3;
var size = data3.length;
data3.forEach(function(data) {
var name = data.name;
var address = data.address;
console.log(name, address);
});
Also you need to change the loop structure. The for..in used to iterate over objects not array of objects.
This works for me;
- var cdata = {"data1":"data1","data2":"data2","data3":[{"name":"ABC","address":"India"},{"name":"DEF","address":"Australia"}]};
each data in cdata.data3
- var name = data.name;
- var address = data.address;
p Name: #{name}
p Address: #{address}
Can you share the actual jade file contents if updating the code as shown above doesn't work. Also what version of jade and express?
