when put formula on script editor using setformula() function, formula contains spaces 'abc list'!, shows syntax error when script saved. i saw answers mention putting + till looks '+abc list+'! didnt work (and if did, formula wouldn't work on normal cell). i'm curious - there no way write formulas reference sheets spaces in names in script editor? both of these work: spreadsheetapp.getactive().getsheetbyname('reports').getrange("g14").setformula('\'january 2017\'!a1'); spreadsheetapp.getactive().getsheetbyname('reports').getrange("g15").setformula("'january 2017'!a1");
