Allow script to run as admin to update spreadsheet - google-apps-script

Question

I have a spreadsheet that is shared with some other users. Many of the cell are range protected. However, through a menu I allow a user to run a script (which access an external library therefore invisible and not in the control of the user) that will modify some of the protected ranges. However, the script throws that there is no permission to perform this operation.
Is there any option to have this library run with library 'admin' rights so it doesn't throws due to protection?
Thx!

Answer 1

According to the documentation : "the library does not have its own instance of the feature/resource and instead is using the one created by the script that invoked it. "
So library is not the way to go.
You can achieve that behavior using a standalone script that would run as a service (a doGet() function in a deployed webapp) that you would deploy as "running as you" and that you would call with parameters to tell it what to do on the target spreadsheet range.
Edit : in its most basic implementation you can use a simple script like this one as a server app :
function doGet(e) {
if(e.parameter.mode==null){return ContentService.createTextOutput("error, wrong request").setMimeType(ContentService.MimeType.TEXT)};
var coord = e.parameter.coord;
var mode = e.parameter.mode;
var value = e.parameter.value;
var ss = SpreadsheetApp.openById('11myX1YX_________________FS6BesaBEnQ');
var sh = ss.getSheetByName(e.parameter.sN);
if(mode=='r'){
var sheetValue = JSON.stringify(sh.getRange(coord).getValue());
var valToReturn = ContentService.createTextOutput(sheetValue).setMimeType(ContentService.MimeType.JSON);
return valToReturn;
}
if(mode=='w'){
sh.getRange(coord).setValue(value);
return ContentService.createTextOutput(value).setMimeType(ContentService.MimeType.JSON);
}
return ContentService.createTextOutput('error').setMimeType(ContentService.MimeType.TEXT);
}
The above script should be deployed with the following parameters :
Then you can use it with a simple urlFetch like below :
var url = "https://script.google.com/macros/s/AKfycbxs9M0ib-VRmmcVJ0UUJXmHITOrWcoG8bYrK4EK7Tvl0krzsYc/exec"
function testServerLink(){
var coord = 'A3';//coordinates in A1 notation
var sheetName = 'Sheet1';
var data = 'test value';
var mode = 'w';// w for "write" and r for "read"
var write = sheetService(mode,coord,sheetName,data);
Logger.log(write);//shows the result in logger
var read = sheetService('r','A1',sheetName,data);
Logger.log(read);//shows the value that was in A1 cell
}
function sheetService(mode,coord,sheetName,data){
Logger.log(url+"?mode="+mode+"&coord="+coord+"&sN="+sheetName+"&value="+data);// shows the actual url with parameters, can be tested in a browser
var result = UrlFetchApp.fetch(url+"?mode="+mode+"&coord="+coord+"&sN="+sheetName+"&value="+data);
return result
}
