Updating a google spreadsheet table with an excel file - excel

Question

I need to update a table that is shared. The info for this table is first collected into an Excel table files and then uploaded to google drive every day. I found some code that converts the .xls files to a google spreadsheet file, I need to copy the data from this converted file and update the shared one each day. My problem now is that the file I will use for updating the shared spreadsheet will be different eachday, so how can I have the script to get the new file ID eachday. I need these updates to be done automatically each day.
This is the code I have found so far but can't seem to get it to work. First part converts the .xls file to google spreadsheet file that part works but i cant seem to get the function for updating the shared table to work, i cant get the ID of the created file. Would also be nice if a function an be added to the code to to delete the files after they have been converted and the shared table has been updated with them.
function importXLS(){
var files = DriveApp.searchFiles('title contains ".xls"');
var destinationFolderId = "ID of folder with .xls file that is being converted each day";
var existingFileNames = getFilesInFolder(destinationFolderId);
while(files.hasNext()){
var xFile = files.next();
var name = xFile.getName();
try {
if (existingFileNames[name] && (name.indexOf('.xls')>-1)) {
var ID = xFile.getId();
var xBlob = xFile.getBlob();
var newFile = { title : name,
key : ID,
'parents':[{"id": destinationFolderId}]
}
file = Drive.Files.insert(newFile, xBlob, {
convert: true
});
}
} catch (error) {
console.error("Error with file " + name + ": " + error);
}
}
}
/**
* Get an object of all file names in the specified folder.
* #param {string} folderId
* #returns {Object} files - {filename: true}
*/
function getFilesInFolder(folderId) {
var folder = DriveApp.getFolderById(folderId);
var filesIterator = folder.getFiles();
var files = {};
while (filesIterator.hasNext()) {
var file = filesIterator.next();
files[file.getName()] = true;
}
return files;
}
function CopyContent() {
var ID = importXLS(ID);
var source = SpreadsheetApp.openById(importXLS(ID));//the source needs to be the new file i get eachday
var sheet = source.getSheets()[0];
var destination = SpreadsheetApp.openById("ID of shared table here");
sheet.copyTo(destination);
}

Use Paste Special > Paste values only
The copypastetype to use is PASTE_VALUES
Example from https://developers.google.com/apps-script/reference/spreadsheet/range#copytodestination-copypastetype-transposed
// The code below copies only the values of the first 5 columns over to the 6th column.
var sheet = SpreadsheetApp.getActiveSheet();
sheet.getRange("A:E").copyTo(sheet.getRange("F1"), spreadsheetApp.CopyPasteType.PASTE_VALUES);
