Exception: Bad value (line 9, file "Code") - firebase

Question

I want to read my data from my firebase and write it in google sheet. When i run this Apps Script I got the error
Exception: Bad value (line 9, file "Code")
var ss= SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName('Sheet1');
var range=sheet.getRange(1,1,4,2);
var data= getFirebaseData("Entries");
Logger.log(data)
range.setValues(JSON.parse(data))
}
function getFirebaseData(data){
var firebaseUrl = "**";
var secret = "**";
var base = FirebaseApp.getDatabaseByUrl(firebaseUrl,secret);
var result = base.getData(data);
return result;
}
the data in Firebase is like this:
Entries
date:"09/09/2020"
docAmount:88
docNo:55
partyName: "ffg"
Solutions that I might accept,(solve this issue)or (show a better way to do the process)

Answer 1

You want to write an object's (data) key/value pairs to two columns in a sheet. setValues accepts a 2D array, not an object, so you should first transform data to a 2D array:
const array = Object.keys(data).map(key => [key, data[key]]);
sheet.getRange(1, 1, array.length, array[0].length).setValues(array);
Note:
Making the range dimensions dependent on the array dimensions (array.length, array[0].length) will give you more flexibility (what if the object has 5 properties instead of 4?).
This will only work for simple objects, not if they have nested properties.
Reference:
setValues(values)
Object.keys()
getData(path, optQueryParameters)
