# Check a non empty cell if not protected then protect it [closed]

I'm using below script to check if cell is non empty then protect it.

BUT

I want to also check if that non empty cell is unprotected then only protect it.

How to do that in below script ???

function onOpen() {
var range = SpreadsheetApp.getActiveSheet().getDataRange();
//range.unprotect();
var values = range.getValues();
for (var i = 0; i < values.length; i++) {
for (var j = 0; j < values[i].length; j++) {
if (values[i][j] !== "") {
range.getCell(i + 1, j +
1).protect().setDescription("lock").removeEditor('xxx.........@gmail.com');
}
}
}
}
