Automatic rostering in Google Sheets

I need help in rostering employees. I did it in MS. Excel but I don't know how to do it in google Sheets scripts.

I want the same to be implemented in google sheets

Please, post text data. Not image.

Probably you need something like this:

function rostering() {
  var ss = SpreadsheetApp.getActiveSheet();
  var emps = [];

  emps[0] = 'OOXXXXX';
  emps[1] = 'XOOXXXX';
  emps[2] = 'XXOOXXX';
  emps[3] = 'XXXOOXX';
  emps[4] = 'XXXXOOX';
  emps[5] = 'XXXXXOO';
  emps[6] = 'OOXXXXX';
  emps[7] = 'XOOXXXX';
  emps[8] = 'XXOOXXX';
  emps[9] = 'XXXOOXX';

  emps = emps.map(e => new Array(5).fill(e).join('').slice(0,31).split(''));

  ss.getRange(2,3,emps.length,31).setValues(emps);
}

The crazy one-liner, just for fun:

function rostering_one_line() {
  SpreadsheetApp.getActiveSheet().getRange(2,3,10,31).setValues (
    ['OOXXXXX','XOOXXXX','XXOOXXX','XXXOOXX','XXXXOOX','XXXXXOO','OOXXXXX','XOOXXXX','XXOOXXX','XXXOOXX']
    .map(e => new Array(5).fill(e).join('').slice(0,31).split('')) );
}
