setFormulas won't skip empty array elements, over-writes values

Question

Consider the code below: it sets values then sets functions across a range, however it overwrites the values that were set.

function test() {
  var ss = Spre         


        

Answer 1

This certainly explains why setting values overwrites formulas, but wouldn't it be nicer if there were a way to getValuesandFormulas together into an array?

If (like me) you were distracted into getValues and getFormulas, realise that you can use copyTo between ranges to copy the overall contents!

Answer 2

I think the problem can be largely mitigated by the fact that setValues() can be used to set formulae.

  var range = ss.getRange("A1:B2");
  var values = range.getValues();

  // process the array, eg values[0][0] = "=42";

  range.setValues();
