Missing Headers row and Leaving space-CodePudding

I was working with a combine sheets app script which is working fine at the spot by mereging A bunch of 36 sheetsinto one masterenter code here the only flaw of the script is that it is not showing a common header row in the top and also leaving a space after data end from first sheets and so on >>> here the code can anyone help a bit here

function combineSheets() {
  var sApp = SpreadsheetApp.getActiveSpreadsheet();
  var s1= sApp.getSheetByName("A1");
  var s2= sApp.getSheetByName("A2");

Modification points:

About not showing a common header row in the top, in your script, all values are retrieved from the 2nd row. I thought that this might be the reason for your issue. From a common header row, in this modification, the header row is retrieved from the 1st sheet.
About also leaving a space after data end from first sheets and so on, I thought that the reason of your issue is due to getRange(2,1,s1.getLastRow(),27). In this case, the values are retrieved from 2nd row to the last row 1 rows. In this case, it required to be getRange(2,1,s1.getLastRow() - 1,27).
In your script, I thought that the sheet names from "A1" to "A36" can be created using a script.

When these points are reflected in your script, it becomes as follows.

Modified script:

function combineSheets() {
  var sApp = SpreadsheetApp.getActiveSpreadsheet();
  var values = [...Array(36)].map((_, i) => `A${i   1}`).flatMap((s, i) => {
    var sheet = sApp.getSheetByName(s);
    var lastRow = sheet.getLastRow();
    if (i == 0) {
      return sheet.getRange(1, 1, lastRow, 27).getValues();
    }
    return lastRow > 1 ? sheet.getRange(2, 1, lastRow - 1, 27).getValues() : [];
  });
  sApp.getSheetByName("Master").getRange(1, 1, values.length, 27).setValues(values);
}

The headr row is retrieved from the 1st sheet.

Note:

In this modification, it supposes that the sheet names of "A1" to "A36" and "Master" are existing in your Spreadsheet. Please be careful about this.
From a common header row in the top, this script supposes that your all sheets have the same header row. Please be careful about this.
About Exception: The number of rows in the range must be at least 1. AT HERE................var values = [...Array(36)].map((_, i) => A${i 1}).flatMap((s, i) => { var sheet = sApp.getSheetByName(s); return sheet.getRange(i == 0 ? 1 : 2, 1, sheet.getLastRow() - (i == 0 ? 0 : 1), 27).getValues(); , from your question, I had thought that your all sheets have the values. But from your reply, it seems that my understanding was not correct. So, I updated my proposed script. Could you please confirm it?
