Google sheet protect based on cell value

Question

I have like 30 tabs in one google sheet file and all of them have the same structure but different data

I want a script that locks (protect) the whole sheet based on the value

this value is defined as range and I want to lock the tab if the value is (audited)

• cell position : A5
• cell value : "audited"

Answer 1

function protectAudited() {
  var ss=SpreadsheetApp.getActive();
  var shts=ss.getSheets();
  shts.forEach(function(sh) {
    if(sh.getRange('A5').getValue()=='audited') {
      sh.protect();
    }
  });
}

Perhaps like this:

function protectAudited() {
  var ss=SpreadsheetApp.getActive();
  var shts=ss.getSheets();
  shts.forEach(function(sh) {
    if(sh.getRange('A5').getValue()=='Audited') {
      sh.protect();
    }else {
      var protection=sh.getProtections(SpreadsheetApp.ProtectionType.SHEET)[0];
      if(protection && protection.canEdit()) {
        protection.remove();
      }
    }
  });
}
