Collect data from multiple spreadsheets into one spreadsheet - google-apps-script

Question

I have 184 audit sheets in one folder. I want to reference one cell in each of these sheets and bring them back in to one master spreadsheet.
I have a code that does the opposite that sends a value to each sheet in the folder and changes it to the value that I want. So in essence I want to do the opposite of the script below:
function getdata() {
var files = DriveApp.getFolderById("1gbA2JI1DYNku7SQPaCq1Qk27hnbimPag").getFiles()
while (files.hasNext()) {
var file = files.next();
var shoot = SpreadsheetApp.openById(file.getId());
var sourcesheet = SpreadsheetApp.getActive().getSheetByName("Jan");
var sourcerange = sourcesheet.getRange('A3');
var sourcevalues = sourcerange.getValues();
var destsheet = shoot.getSheetByName('Front Sheet');
var destrange = destsheet.getRange('B5');
destrange.setValues(sourcevalues);
}
}

Your example code doesn't appear to match your explanation but I think I got the basic idea so I made up some of the needed details on my own. I included filenames, ids and 'A3' values. You can choose to modify as needed.
function getdata(month) {
var monthA=["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"];
var date=new Date();
var mss=SpreadsheetApp.getActive();
var ms=mss.getSheetByName("Master Sheet");
var vObj={name:[],id:[],value:[]};
var files = DriveApp.getFolderById("1gbA2JI1DYNku7SQPaCq1Qk27hnbimPag").getFilesByType(MimeType.GOOGLE_SHEETS);
while (files.hasNext()) {
var file = files.next();
var fid=file.getId();
var ss = SpreadsheetApp.openById(fid);
var sh = ss.getSheetByName(monthA[date.getMonth()]);
var rg = sh.getRange('A3');
vObj.name.push(file.getName());
vObj.id.push(fid);
vObj.value.push(rg.getValue());
vObj['month']=monthA[date.getMonth()];
}
vObj.id.splice(0,0,'ids');
ms.appendRow(vObj.id);
vObj.name.splice(0,0,vObj.month);
ms.appendRow(vObj.name);
vObj.value.splice(0,0,'values');
ms.appendRow(vObj.value)
}
