Answer:

You can define a textFinder and run it over your data range.

Code:

function findSam() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];  
  var range = sheet.getDataRange();
  var textFinder = range.createTextFinder('Sam');
  var locations = [];
  
  var occurrences = textFinder.findAll().map(x => x.getA1Notation());
  
  if (occurrences == []) {
    // do something if "Sam" not in sheet 
  }
  else {
    // do stuff with each range: 
  }  
}

This code will:

• Find all cells that contain "Sam" in the first sheet of the Spreadsheet
• Append the Range object that contains "Sam" to an array of ranges
• Map the array of ranges to an array of A1 notations which are all the cells which contain "Sam".

From here you can do what you wish with the ranges. If "Sam" is not in the sheet then occurrences will be an empty array and you can do here what you wish.

I hope this is helpful to you!
