Master Data Sheet from a folder without Blank spaces between pulled files - google-apps-script

Question

I know there has been a lot said on the topic of a Master Sheet already. However as I haven't found the relevant answer to my question, I was hoping you could be so kind and help. The issue is very trivial I have a script that looks into the specific folder and grabs the data from those sheets. I just don't know how to modify it so that it doesn't retrieve the empty cells too ( due to the import range function sitting in the subfiles). So in the nutshell, it would be great if the code will only retrieve a range of data, for column "A" <> ""
function myFunction() {
var folder = DriveApp.getFolderById("xcv");
var filesInterator = folder.getFiles();
var file;
var fileType;
var ssID;
var combinedData = [];
var data;
while(filesInterator.hasNext()){
file = filesInterator.next();
fileType = file.getMimeType();
if(fileType === "application/vnd.google-apps.spreadsheet"){
ssID = file.getId();
data = getDataFromSpreadsheet(ssID);
combinedData = combinedData.concat(data);
} // if ends here
} // while loops ends here
Logger.log(combinedData.length);
var ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Master");
ws.getRange("A2:BK").clearContent();
ws.getRange(2,1,combinedData.length,combinedData[0].length).setValues(combinedData);
}
function getDataFromSpreadsheet(ssID) {
var ss = SpreadsheetApp.openById(ssID);
var ws = ss.getSheetByName("ABC");
var data = ws.getRange("A2:KB" + ws.getLastRow()).getValues();
return data;
}

Answer 1

Try this:
function getDataFromSpreadsheet(ssID) {
var ss = SpreadsheetApp.openById(ssID);
var ws = ss.getSheetByName("ABC");
var data = ws.getRange("A2:KB" + ws.getLastRow()).getValues().filter(r => r[0] != ''});
return data;
}
Array.filter()
