How to format text on all sheets of Google Sheets at once?

Question

Google Sheets

I have a google spreadsheet with 10 sheets. I want to change the font in each. Are there extensions or ways that can do this for the entire table as a whole?

Answer 1

1) Record actions on one sheet
with a macro recorder 2) Edit the script so that it works on all sheets
3) Run the function

let sheets = SpreadsheetApp.getActiveSpreadsheet().getSheets();
  for (var sheet in sheets){
    // do something
    // Очередной лист - sheets[sheet]
  };
