Trying to append rows what am I not grasping? - google-apps-script

Question

Summary:
I need to get a range of values from one sheet, then set them into the first empty row of the second sheet. If that row is full, then append to the next.
I can get the script to set values into their corresponding cells, but not append; and I've been able to append a single cell value into an empty cell, but not the entire range. What am I not comprehending?
The goal:
Basically I'm taking user input (lets say race data) and saving it to another sheet for referencing later. (possibly to average race times by weight and height or something)
Research: I'm a bit new to this, but I've also done a good bit of research, such as ben collins free introductory course and other questions from here (just to name a couple):
[Get Range] SpreadsheetApp: getRange and setValues
[Copy Range] How to copy row ranges in Google docs?
Code
Grab my data:
const data1 = sheet1.getRange("A2:F2").getValues(); //grab data
Sets the range where I want it, but doesn't append:
sheet2.getRange("A2:F2").setValues(data1) //gets range and sets the value
So I've tried:
function r () {sheet2.getRange(newRow,1,1,data1.length).setValues(data1)};
return (r);
and even added:
sheet2.appendRow(data1);
(newRow is essentially getLastRow)
The above gives me a row of set values, then appends this in the following row: [Ljava.lang.Object;#f2a6014
-which in my research I've found what it is, but I don't understand why it happens.
I know I'm overlooking something or arranging something incorrectly but I cant figure out what it is that I'm not understanding.

Answer 1

Using your first two example I wrote this script and it works:
function copydata() {
const ss=SpreadsheetApp.getActive();
const sheet1=ss.getSheetByName('Sheet1');
const sheet2=ss.getSheetByName('Sheet2');
const data1 = sheet1.getRange("A2:F2").getValues();
sheet2.getRange("A2:F2").setValues(data1);
}
And this works also assuming that you realize that data1 is only a single row but it's still a two dimensional array so you have to use data1[0] to extract the single dimensional array from the two dimensional array
function copydatatofrom() {
const ss=SpreadsheetApp.getActive();
const sheet1=ss.getSheetByName('Sheet1');
const sheet2=ss.getSheetByName('Sheet2');
const data1 = sheet1.getRange("A2:F2").getValues();
sheet2.getRange("A2:F2").setValues(data1);
sheet2.appendRow(data1[0]);
}
