SpreadsheetApp.getUi().alert('foo bar')

When I use this piece of code, it appears as 'foo bar', removing the additional spaces in between. is there a way coerce Google App Script to do otherwise? It appears to only remove additional spaces, which makes sense, but I'd rather have spaces than dashes. If there isn't a way to do it through the UI API, what alternatives do I have?

Instead of using spaces consider using non-breaking spaces \xa0 instead.

The following code uses the String.prototype.replace with a regular expression / /g * to replace all spaces with non-breaking spaces.
* Global flag g is required or it'll only replace the 1st space.

function myFunction() {
  const message = 'foo        bar'.replace(/ /g,'\xa0');

If using this repeatedly in your script, you could also create a function and call it where needed:

function myFunction() {
  const message = noBreakSpaces('foo        bar');
  function noBreakSpaces(txt) {
    return txt.replace(/ /g, '\xa0');
  • Oh thanks this works! That's a nifty trick I'll keep in mind.

I created a short function from Rubén's solution:

function SpaceBuilder(spaces){  
    var mySpaces = ' ';  
    for(var nnn=1;nnn<spaces;nnn++){  
        mySpaces = mySpaces + ' ';  
    return mySpaces.replace(/ /g,'\xa0');  


var xxx = SpaceBuilder(5);  
Ui.alert('Hello' + xxx + 'World')


Hello     World

    OP doesn't indicate a need for reuse but even so, this seems to add new requirements unnecessarily. This seems to be an answer to a different question. See the updated accepted answer for how the functionality could be transferred to a function without changing the requirements.
