Script to automatically capitalize contents of a cell in Google Sheets?

Question

I have a spreadsheet that takes input of stock symbols. I would like them to always be in ALL CAPS regardless of how they are typed in. This appears to require some scripting

Answer 1

So, anyone know a way to do exactly what the above code does, but not touch the actual formulas inside the cells, only the text that they output?

Consider to make a slight change in the OP approach: rather than capitalize all the cells content for any case, capitalize according the following conditions:

1. If the cell value, including the values of cells that holds constants or formulas, is not a string then do nothing .
2. If the cell value is a string
   • and the cell content is a constant, then change the case directly from the script.
   • and the cell content is a formula, then nest the original formula inside the built-in function UPPER.

Example:

function onEdit(e) {
  var range = e.range;
  var value = range.getValue();
  var sheet = range.getSheet();
  var sheetName = sheet.getName();
  if (sheetName === 'Sheet1' && 
      range.getRow() > 1 && 
      range.getColumn() > 1 && 
      typeof value === 'string') {
    if(!range.getFormula()) {
      range.setValue(value.toUpperCase());
    } else {
      if(range.getFormula().substring(0,6).toUpperCase() == '=UPPER') {
        return;
      } else {
        range.setFormula('=UPPER(' + range.getFormula().substring(1) + ')');
      }
    }
  }
}

Notes:

• For simplicity the ind array was not included.
• typeof e.value always returns 'string', so instead range.getValue(); is used.
