A snippet to automatically move to n-row on open in Google Sheets

function onOpen() {
var file = SpreadsheetApp.getActiveSpreadsheet();
var sheet = file.getSheetByName("sheetName");
file.setActiveCell(sheet.getRange(rowNumber, columnNumber));

Where "sheetName" is the name of the sheet you want to move within, rowNumber the number of the desired row, and columnNumber the number of the desired column.
