How can I convert CSV data to JSON data? - javascript

I wrote the code that gets data from a device.
The form of the data is csv. Below is the data value.
1,1.635946,1.636609,1.640240,1.636091
2,1.642825,1.640267,1.639013,1.636568
3,1.636835,1.636022,1.637664,1.637144
4,1.641332,1.641166,1.637950,1.640760
5,1.636041,1.637437,1.640702,1.633678
But I want the data in json format. So I tried using an online converter and got the following values:
[
{
"1": 2,
"1.635946": 1.642825,
"1.636609": 1.640267,
"1.640240": 1.639013,
"1.636091": 1.636568
},
{
"1": 3,
"1.635946": 1.636835,
"1.636609": 1.636022,
"1.640240": 1.637664,
"1.636091": 1.637144
}
]
What parts of my code should I modify if I want to get these values?
Below is my code.
var Timer;
var i = 0 ;
setTimeout(function(){
Timer = setInterval(function(){
port.write(meascommand+'\n');
i++;
if(i==5){
clearInterval(Timer);
}
},5000);
},1000);
port.on('data',function(devicevalue){
arrayvalue = devicevalue.toString();
eachvalue = arrayvalue.split(';');
var results = [];
var index = i ;
var ch0value = eachvalue[0] ;
var ch1value = eachvalue[1] ;
var ch2value = eachvalue[2] ;
var ch3value = eachvalue[3] ;
results[0] = index ;
results[1] = ch0value ;
results[2] = ch1value ;
results[3] = ch2value ;
results[4] = ch3value ;
console.log(results);
fs.appendFile(file,results+'\r\n',function(err){
if(err)
console.log(err);
});
});
};


function processFiles(files) {
var file = files[0];
var reader = new FileReader();
reader.onload = function (e) {
var output = document.getElementById("fileOutput");
var texto = e.target.result;
csvJSON(texto);
};
reader.readAsText(file);
}
function csvJSON(csv) {
var lines = csv.split("\n");
var result = [];
var headers;
for (var i = 0; i < lines.length; i++) {
headers = lines[i].split("\n");
}
var cont = 0;
for (var i = 0; i < lines.length; i++) {
var obj = {};
var currentline = lines[i].split("\n");
for (var j = 0; j < headers.length; j++) {
obj[cont] = currentline[j];
}
cont++;
result.push(obj);
}
return JSON.stringify(result); //JSON
}


Try to use below code. Credits go to: https://gist.github.com/iwek/7154578
NOTE: split(","). If lines contains , snippet won't work. But thats not the case in your data, as far as I can see.
function csvJSON(csv){
var lines=csv.split("\n");
var result = [];
var headers=lines[0].split(",");
for(var i=1;i<lines.length;i++){
var obj = {};
var currentline=lines[i].split(",");
for(var j=0;j<headers.length;j++){
obj[headers[j]] = currentline[j];
}
result.push(obj);
}
//return result; //JavaScript object
return JSON.stringify(result); //JSON
}

Error with setTimeout() function in for loop

I have the following script that I need to adjust so that each iteration has a one second pause before or after it executes the loop (it doesn't really matter which as long as the lag is there). I tried to add the setTimeout() function into the Try section of my code but it is still consistently failing. I also have tried to use "let" instead of "var" in the for loop but that failed as well. Any advice on how to add it in would be very appreciated. I'm having trouble finding an example of a similar setTimeout() function within a for loop online.
var ZB_DataExtension = 'C7_Unsubscribe_Response';
var ZB_DataExtension_Response = 'C7_Unsubscribe_Response';
var ZB_DataExtension_Logs = 'C7_CustUnsubscribe_Logs';
//Endpoint
var zeroBounceFullUrl = 'https://api.commerce7.com/v1//customer/CUST_ID';
//Extract results from Data Extension using DE key
var results = DataExtension.Init(ZB_DataExtension).Rows.Retrieve();
var updateDE_ZB = DataExtension.Init(ZB_DataExtension_Response);
var logsDE_ZB = DataExtension.Init(ZB_DataExtension_Logs);
var today = Format(Now(), "YYYY-MM-DD ");
for (var i = 0; i < results.length; i++ ) {
var item = results[i];
var zeroBounceUrlItem = "";
var ZB_Status = "";
var currentDateTime = Now();
try{
setTimeout(() => (
zeroBounceUrlItem = String(zeroBounceFullUrl).split("CUST_ID").join(String(item.C7_CustID));
var req = new Script.Util.HttpRequest(zeroBounceUrlItem);
req.emptyContentHandling = 0;
req.retries = 3;
req.continueOnError = true;
req.contentType = "application/json";
req.method = "PUT";
var payload='{"emailMarketingStatus": "Unsubscribed"}'
req.postData = payload ;
var resp = req.send();
var returnStatus= resp.returnStatus;
updateDE_ZB.Rows.Update({C7_API_Answer:String(returnStatus),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
if (returnStatus==0) {
updateDE_ZB.Rows.Update({C7_API_Answer:String("Success"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
}
else {
//ZB_Status = String("ERRO ZB API Call");
//var responseJson = Platform.Function.ParseJSON(String(resp.content));
updateDE_ZB.Rows.Update({C7_API_Answer:String("Failure"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
}
var randomID = Platform.Function.GUID();
logsDE_ZB.Rows.Add({log_guid:String(randomID),C7_CustID:String(item.C7_CustID),Status:String("Success"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem)});
), 1000*i}
catch (err) {
var randomID = Platform.Function.GUID();
ZB_Status = String("ERRO AMPScript");
logsDE_ZB.Rows.Add({log_guid:String(randomID),C7_CustID:String(item.C7_CustID),Status:String("Failure"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem)});
}
}
</script>

Your loop will execute the right number of times and at the right interval, but the value of the variable item inside the timeout might not be what you expect.
Try this:
for (var i = 0; i < results.length; i++ ) {
(function(i){
setTimeout(function(){
var item = results[i];
var zeroBounceUrlItem = "";
var ZB_Status = "";
var currentDateTime = Now();
try{
zeroBounceUrlItem = String(zeroBounceFullUrl).split("CUST_ID").join(String(item.C7_CustID));
var req = new Script.Util.HttpRequest(zeroBounceUrlItem);
req.emptyContentHandling = 0;
req.retries = 3;
req.continueOnError = true;
req.contentType = "application/json";
req.method = "PUT";
var payload='{"emailMarketingStatus": "Unsubscribed"}'
req.postData = payload ;
var resp = req.send();
var returnStatus= resp.returnStatus;
updateDE_ZB.Rows.Update({C7_API_Answer:String(returnStatus),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
if (returnStatus==0) {
updateDE_ZB.Rows.Update({C7_API_Answer:String("Success"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
}
else {
//ZB_Status = String("ERRO ZB API Call");
//var responseJson = Platform.Function.ParseJSON(String(resp.content));
updateDE_ZB.Rows.Update({C7_API_Answer:String("Failure"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem),EmailAddress:String(item.EmailAddress)}, ["C7_CustID"], [String(item.C7_CustID)]);
}
var randomID = Platform.Function.GUID();
logsDE_ZB.Rows.Add({log_guid:String(randomID),C7_CustID:String(item.C7_CustID),Status:String("Success"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem)});
catch (err) {
var randomID = Platform.Function.GUID();
ZB_Status = String("ERRO AMPScript");
logsDE_ZB.Rows.Add({log_guid:String(randomID),C7_CustID:String(item.C7_CustID),Status:String("Failure"),ValidationDate:currentDateTime,ValidationUrl:String(zeroBounceUrlItem)});
}
}, i*1000);

Can we able to update a particular cell in csv file using Javascript?

Can we able to update a particular cell in csv file using Javascript?
Can anyone share please share the sample javascript code?

Considering you have a workbook, here is how you may loop through the rows and change the cell value:
var rows = workbook.sheets[0].rows;
for (var ri = 0; ri < rows.length; ri++) {
var row = rows[ri];
for (var ci = 0; ci < row.cells.length; ci++) {
var cell = row.cells[ci];
cell.value = new_data;
cell.hAlign = "left";
}
}
Update
var file = document.getElementById('docpicker')
file.addEventListener('change', importFile);
function importFile(evt) {
var f = evt.target.files[0];
if (f) {
var r = new FileReader();
r.onload = e => {
var contents = processExcel(e.target.result);
console.log(contents)
}
r.readAsBinaryString(f);
} else {
console.log("Failed to load file");
}
}
function processExcel(data) {
var workbook = XLSX.read(data, {
type: 'binary'
});
// inject your logic as per need
var rows = workbook.sheets[0].rows;
for (var ri = 0; ri < rows.length; ri++) {
var row = rows[ri];
for (var ci = 0; ci < row.cells.length; ci++) {
var cell = row.cells[ci];
cell.value = new_data;
cell.hAlign = "left";
}
}
};

Google sheets incorrect range width when no cmc matches

I am using this function to pull information from coinmarketcap using their v2 api. The problem I am getting is that if a "website_slug" does not exist on coinmarketcap, I get an incorrect range width error instead of the function just putting xxx in the cell. This can be recreated by having a cell in column B that doesn't match a website_slug on cmc (https://api.coinmarketcap.com/v2/ticker/).
function getMarketCap(sheetname) {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName(sheetname);
var assets = [];
var idRange = sheet.getRange("B1:B");
var lastRow = getLastRowOfRange(idRange);
var cellRange = sheet.getRange(1, 2, lastRow).getValues();
var mcRange = sheet.getRange(1, 3, lastRow);
var mcValues = [];
for (var i = 0; i < cellRange.length; i++) {
assets[i] = cellRange[i];
}
var req = [];
for (var i = 0; i < 16; i++) {
req.push({
muteHttpExceptions: true,
method: "get",
url: "https://api.coinmarketcap.com/v2/ticker/?start=" + (i * 100 + 1),
});
}
var responses = UrlFetchApp.fetchAll(req);
var res = responses.filter(function(e){return e.getResponseCode() == 200}).map(function(e){return JSON.parse(e.getContentText())});
if (responses.length != res.length) Logger.log("%s errors occurred.", responses.length - res.length);
var mcValues = [];
assets.forEach(function(e, h) {
mcValues[h] = []
res.some(function(f) {
Object.keys(f.data).some(function(g) {
if (f.data[g].website_slug == e[0]) {
mcValues[h][0] = f.data[g].quotes.USD.market_cap;
return true;
}
});
if (mcValues[h][0]) return true;
});
if (!mcValues[h][0]) mcValues[h][0] = 'xxx';
});
mcRange.setValues(mcValues);
}

How do I build my JSON object using two parts when concatenated together produces the correct JSON data path

Is this possible to do, or how do I do it?
arrayElement = new Object();
JSONkey = jsonData.table[0].key; // key in table[0] is "ident/Lesson/Value"
JSONkey = JSONkey.replace(/\//g, '.'); // now JSONkey is "ident.Lesson.Value"
arrayElement.JSONkey = "value1" // Can I do this or how would I?
So arrayElement.JSONkey is the same as arrayElement.ident.Lesson.Value

arrayElement = new Object();
JSONkey = jsonData.table[0].key; // key in table[0] is "ident/Lesson/Value"
JSONkey = JSONkey.replace(/\//g, '.'); // now JSONkey is "ident.Lesson.Value"
deepRef(arrayElement, JSONkey, "value1");
function deepRef(ref, key, value) {
var segments = key.split("."),
n = segments.length;
for (var i=0, skey; i<n; i++) {
skey = segments[i];
if (i < n - 1) {
ref[skey] = {};
ref = ref[skey];
} else {
ref[skey] = value;
}
}
}

compressing string in js and save in localStorage

I'm trying to save a HUGE json string in my localStorage but for some reason sometimes it saves it and sometimes not, I thought I should compress it so I took an LZW implementation in js from one of the threads in stackoverflow.
The problem is when I try to localStorage.setItem() the compressed string it gives me an error "Invalid argument", any idea why or what should I do?
Edit:
this is the code I'm using:
// LZW-compress a string
function lzw_encode(s) {
var dict = {};
var data = (s + "").split("");
var out = [];
var currChar;
var phrase = data[0];
var code = 256;
for (var i=1; i<data.length; i++) {
currChar=data[i];
if (dict[phrase + currChar] != null) {
phrase += currChar;
}
else {
out.push(phrase.length > 1 ? dict[phrase] : phrase.charCodeAt(0));
dict[phrase + currChar] = code;
code++;
phrase=currChar;
}
}
out.push(phrase.length > 1 ? dict[phrase] : phrase.charCodeAt(0));
for (var i=0; i<out.length; i++) {
out[i] = String.fromCharCode(out[i]);
}
return out.join("");
}
// Decompress an LZW-encoded string
function lzw_decode(s) {
var dict = {};
var data = (s + "").split("");
var currChar = data[0];
var oldPhrase = currChar;
var out = [currChar];
var code = 256;
var phrase;
for (var i=1; i<data.length; i++) {
var currCode = data[i].charCodeAt(0);
if (currCode < 256) {
phrase = data[i];
}
else {
phrase = dict[currCode] ? dict[currCode] : (oldPhrase + currChar);
}
out.push(phrase);
currChar = phrase.charAt(0);
dict[code] = oldPhrase + currChar;
code++;
oldPhrase = phrase;
}
return out.join("");
}
this is the code that calls the compressing algorithm and saves it in LS
LOG("GetMerchantList(): Done");
var SITESVAR = unescape(data)
localStorage.setItem("MYSITES", lzw_encode(SITESVAR)); //this throws error
IWT.BuildMerchantList(SITESVAR);
