If var isnumber, for script

Question

I need to run a script which contains the logic: If isNumber, Then DoSomething.

I\'ve run other such if then tests such as if blank, and if cell contains \"

Answer 1

Google Apps Script could use most of the JavaScript methods and operators.

One alternative to check if an object is a number is to use typeof.

The following code will return the type of the value of the cell specified by the reference.

function typeofcellvalue(reference) {
  var ss = SpreadsheetApp.getActive();
  var rng = ss.getRange(reference);
  var value = rng.getValue();
  return typeof value;
}

Example of use as a custom function

=typeofcellvalue("A1")

If cell A1

• has a number, the result will be number.
• is empty, the result will be string.
