How to restore a JSON string from a compressed blob in Google Apps Script?

I need to store a large json into a cell of a spreadsheet. Since there's a 50k character limit I thought of compressing the json string. I've managed to store the compressed blob as a base64 encoded string, but I'm failing to restore it to the original json. When the readLargeJson function is called I get the following error: "Blob object must have non-null content type for this operation".
The insertLargeJson function below seems to be working correctly.
I tried also storing without the base64 encoding, but didn't help.
function insertLargeJson()
{
var obj = {};
obj["dummy"] = [];
// Just to make the json huge
for (var i = 0; i < 10000; i++)
{
obj["dummy"].push("value");
}
var activeSheet = SpreadsheetApp.getActiveSheet();
var str = JSON.stringify(obj);
var blob = Utilities.newBlob(str, 'application/octet-stream');
var compressedBlob = Utilities.zip([blob]);
var encoded = Utilities.base64Encode(compressedBlob.getDataAsString());
activeSheet.getRange(1, 1).setValue(encoded);
}
function readLargeJson()
{
var activeSheet = SpreadsheetApp.getActiveSheet();
var values = activeSheet.getSheetValues(1, 1, 1, 1);
var value = values[0, 0];
var decoded = Utilities.base64Decode(value);
var blob = Utilities.newBlob(decoded);
var unzipped = Utilities.unzip(blob);
var obj = JSON.parse(unzipped.getDataAsString());
Browser.msgBox('Test Json array size', "" + obj["dummy"].length, Browser.Buttons.OK);
}
I don't necessarily need to use the blob interface to compress the json, any solution that would compress the json string and that would be storable in a cell for later retrieving the original json would work.

It is an interesting concept so I search a bit and get something working.
In your code you have to use compressedBlob.getBytes() to encode data and not compressedBlob.getDataAsString(). To create a blob in your read function you must use bytes in input.
Then in your read function the unzip return an array and before to get the data you have to use the getAs() function. So you must have unzipped[0].getAs('application/octet-stream').getDataAsString() and not unzipped.getDataAsString()
I made a single function to ease testing, so you just have to split it depending your need.
function insertReadLargeJson(){
var obj = {};
obj["dummy"] = [];
// Just to make the json huge
for (var i = 0; i < 10000; i++)
{
obj["dummy"].push("value");
}
// Logger.log(obj)
var activeSheet = SpreadsheetApp.getActiveSheet();
var str = JSON.stringify(obj);
var blob = Utilities.newBlob(str, 'application/octet-stream');
var compressedBlob = Utilities.zip([blob]);
var encoded = Utilities.base64Encode(compressedBlob.getBytes());
activeSheet.getRange(1, 1).setValue(encoded);
var decoded = Utilities.base64Decode(encoded);
var blob = Utilities.newBlob(decoded,'application/zip');
var unzipped = Utilities.unzip(blob);
var obj = JSON.parse(unzipped[0].getAs('application/octet-stream').getDataAsString());
// Logger.log(JSON.stringify(obj))
Logger.log(obj.dummy.length)
// Logger.log('Test Json array size', "" + obj["dummy"].length)
}

I was able to do it with the help of an external library.
I converted the code to be readable by Apps Script:

}
var activeSheet = SpreadsheetApp.getActiveSheet();
var packed = pack(obj);
var value = JSON.stringify(packed);
activeSheet.getRange(1, 1).setValue(value);
}
function readLargeJson()
{
var activeSheet = SpreadsheetApp.getActiveSheet();
var value = activeSheet.getRange(1,1).getValue();
var packed = JSON.parse(value);
var obj = unpack(packed);
Browser.msgBox('Test Json array size', "" + obj["dummy"].length, Browser.Buttons.OK);
}
Hope this helps!

xml2json - "X2JS is not defined"

Apologies if I've gone about this in the wrong way. I've done;
npm install xml2json
Which didn't flag up any errors but I still can't seem to get the data to load correctly.

Solution that after you import <script> from package x2js, you should use window.X2JS to get constructor of X2JS. Almost packages implementing for both NPM and browser, the browser version usually use via object window, because it is shared and free connected in almost browsers.
This is my demo for the solution: https://jsfiddle.net/huynhsamha/2evdgt7r/
In my demo, I've include package x2js from NPM here https://unpkg.com/x2js#3.2.3/x2js.js
var X2JS = window.X2JS;
var x2js = new X2JS();
const data = {
a: {
b: 1
},
c: [1, 2]
}
console.log(x2js.js2xml(data))
// <a><b>1</b></a><c>1</c><c>2</c>

Need to work this string in as a parameter in my url

I have a filter script that ads a value to my url trough a set of checkboxes. Each checkbox group can only ad one value.
First click on a checkboxgroup looks like this:
/Network-CAT-cables?fss=yellow
Where the fss=yellow is the added parameter. A click on another chekcbox group would look like this:
/Network-CAT-cables?fss=yellow+cat6
If I check another checkbox in one of the above groups it replaces the previous value.
Now i need to add a parameter that looks like this:
&sps=d211av450240_2.0
If I set that as a value in the checkbox it kinda work. It ads the parameter and sort after it. And if i add a "normal" value it places before it. and that works too - like this:
?fss=yellow+cat5&sps=d211av450240_2.0
The problem is that when I have several of the new custom parameter in a group. In the other checkbox groups I can only have one value - and the chosen one replaces the old parameter. with the custom parameter I want to add it just ads on, instead of replaceing - like this.
?fss=yellow+cat5&sps=d211av450240_2.0+&sps=d211av450240_1.0
The correct outcome would have been
?fss=yellow+cat5&sps=d211av450240_1.0
I know this is because of the "&" in the parameter - but unsure how to work it out. I cant change the parameter either - and I know checkboxes are ment to be for multiple choices, but its like this for a reason.
My filterscript:

Easy way to get multi-level javascript object property

I always need to deal with multi-level js objects where existence of properties are not certain:
try { value1 = obj.a.b.c; } catch(e) { value1 = 1; }
try { value2 = obj.d.e.f; } catch(e) { value2 = 2; }
......
Is there an easier way or a generic function (e.g. ifnull(obj.d.e.f, 2) ) that does not require a lot of try catches?

var value1 = (obj.a && obj.a.b && obj.a.b.c) || 1;
http://jsfiddle.net/DerekL/UfJEQ/
Or use this:
function ifNull(obj, key, defVal){
var keys = key.split("."), value;
for(var i = 0; i < keys.length; i++){
if(typeof obj[keys[i]] !== "undefined"){
value = obj = obj[keys[i]];
}else{
return defVal;
}
}
return value;
}
var value1 = ifNull(obj, "a.b.c", 1);

You could always create a helper function.
function isUndefined(root, path, defaultVal) {
var parts = path.split('.'),
i = 0,
len = parts.length,
o = root || {}, v;
while ((typeof (v = o[parts[i]]) === 'object', o = v) && ++i < len);
return (typeof v === 'undefined' || i !== len)? defaultVal: v;
}
var obj = {a: { b: { test: 'test' }}}, v;
v = isUndefined(obj, 'a.b.test', 1); //test
v = isUndefined(obj, 'a.test', 1); //1

Using lodash you can do this easily**(node exists and empty check for that node)**..
var lodash = require('lodash-contrib');
function invalidateRequest(obj, param) {
var valid = true;
param.forEach(function(val) {
if(!lodash.hasPath(obj, val)) {
valid = false;
} else {
if(lodash.getPath(obj, val) == null || lodash.getPath(obj, val) == undefined || lodash.getPath(obj, val) == '') {
valid = false;
}
}
});
return valid;
}
Usage:
leaveDetails = {
"startDay": 1414998000000,
"endDay": 1415084400000,
"test": { "test1" : 1234 }
};
var validate;
validate = invalidateRequest(leaveDetails, ['startDay', 'endDay', 'test.test1']);
it will return boolean.

Sorting two similar tables simultaneously

I've two tables which has exactly same columns. These tables are placed besides each other. Currently they are sorted separately. I want them to be sorted together. i.e. when I click on first column header of table 1 both tables should be sorted as if both are a single table.
This is the .js which I am using
function SortableTable (tableEl) {
this.tbody = tableEl.getElementsByTagName('tbody');
this.thead = tableEl.getElementsByTagName('thead');
this.tfoot = tableEl.getElementsByTagName('tfoot');
this.getInnerText = function (el) {
if (typeof(el.textContent) != 'undefined') return el.textContent;
if (typeof(el.innerText) != 'undefined') return el.innerText;
if (typeof(el.innerHTML) == 'string') return el.innerHTML.replace(/<[^<>]+>/g,'');
}
this.getParent = function (el, pTagName) {
if (el == null) return null;
else if (el.nodeType == 1 && el.tagName.toLowerCase() == pTagName.toLowerCase())
return el;
else
return this.getParent(el.parentNode, pTagName);
}
this.sort = function (cell) {
var column = cell.cellIndex;
var itm = this.getInnerText(this.tbody[0].rows[1].cells[column]);
var sortfn = this.sortCaseInsensitive;
if (itm.match(/\d\d[-]+\d\d[-]+\d\d\d\d/)) sortfn = this.sortDate; // date format mm-dd-yyyy
if (itm.replace(/^\s+|\s+$/g,"").match(/^[\d\.]+$/)) sortfn = this.sortNumeric;
this.sortColumnIndex = column;
var newRows = new Array();
for (j = 0; j < this.tbody[0].rows.length; j++) {
newRows[j] = this.tbody[0].rows[j];
}
newRows.sort(sortfn);
if (cell.getAttribute("sortdir") == 'down') {
newRows.reverse();
cell.setAttribute('sortdir','up');
} else {
cell.setAttribute('sortdir','down');
}
for (i=0;i<newRows.length;i++) {
this.tbody[0].appendChild(newRows[i]);
}
}
this.sortCaseInsensitive = function(a,b) {
aa = thisObject.getInnerText(a.cells[thisObject.sortColumnIndex]).toLowerCase();
bb = thisObject.getInnerText(b.cells[thisObject.sortColumnIndex]).toLowerCase();
if (aa==bb) return 0;
if (aa<bb) return -1;
return 1;
}
this.sortDate = function(a,b) {
aa = thisObject.getInnerText(a.cells[thisObject.sortColumnIndex]);
bb = thisObject.getInnerText(b.cells[thisObject.sortColumnIndex]);
date1 = aa.substr(6,4)+aa.substr(3,2)+aa.substr(0,2);
date2 = bb.substr(6,4)+bb.substr(3,2)+bb.substr(0,2);
if (date1==date2) return 0;
if (date1<date2) return -1;
return 1;
}
this.sortNumeric = function(a,b) {
aa = parseFloat(thisObject.getInnerText(a.cells[thisObject.sortColumnIndex]));
if (isNaN(aa)) aa = 0;
bb = parseFloat(thisObject.getInnerText(b.cells[thisObject.sortColumnIndex]));
if (isNaN(bb)) bb = 0;
return aa-bb;
}
// define variables
var thisObject = this;
var sortSection = this.thead;
// constructor actions
if (!(this.tbody && this.tbody[0].rows && this.tbody[0].rows.length > 0)) return;
if (sortSection && sortSection[0].rows && sortSection[0].rows.length > 0) {
var sortRow = sortSection[0].rows[0];
} else {
return;
}
for (var i=0; i<sortRow.cells.length; i++) {
sortRow.cells[i].sTable = this;
sortRow.cells[i].onclick = function () {
this.sTable.sort(this);
return false;
}
}
}
There are just two columns and are likely to remain the same. Some ideas would be really appreciated.

I don't quite follow the HTML you have (since you didn't include any HTML), so I created a simple version myself here and implemented a sort across tables. The basic idea is that it collects all the data out of the tables into a single javascript data structure, sorts the javascript data structure and then puts all the data back into the tables.
This makes the sorting much simpler and the only places you have to deal with the complexities of multiple tables is when retrieving the data and then putting it back into the tables. You can see it work here: http://jsfiddle.net/jfriend00/Z5ywA/. Just click on a column header to see both tables sorted by that column.
The code is this:
function sortTables(colNum) {
var t1 = document.getElementById("table1");
var t2 = document.getElementById("table2");
var data = [], sortFn;
function sortAlpha(a, b) {
// deal with empty strings
var aa = a[colNum].data, bb = b[colNum].data;
if (!aa) {
return(!bb ? 0 : -1);
} else if (!bb){
return(1);
} else {
return(aa.localeCompare(bb));
}
}
function sortNumeric(a, b) {
// deal with possibly empty strings
var aa = a[colNum].data, bb = b[colNum].data;
if (typeof aa == "string" || typeof bb == "string") {
return(sortAlpha(a, b));
} else {
return(aa - bb);
}
}
// get the data
function getData(table) {
var cells, rowData, matches, item, cellData;
var rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr");
for (var i = 0; i < rows.length; i++) {
rowData = [];
cells = rows[i].getElementsByTagName("td");
for (var j = 0; j < cells.length; j++) {
// add each cell in the row to the rowData data structure
item = {};
item.origStr = cells[j].textContent || cells[j].innerText;
cellData = item.origStr.replace(/^\s*|\s*$/g, "").toLowerCase();
if (cellData.match(/^[\d\.]+$/)) {
cellData= parseFloat(cellData);
} else if (matches = cellData.match(/^(\d+)-(\d+)-(\d+)$/)) {
cellData= new Date(
parseInt(matches[3], 10),
parseInt(matches[1], 10) - 1,
parseInt(matches[2], 10)
);
}
