ipushpull updates your pages on Excel and the web live, so you never need to save your sheet or refresh your browser.
You can set an update interval for each of your pages. This can be as low as one second.
On your Excel spreadsheet, the ipush(...) function updates your pages according to this interval. If your spreadsheet is updating faster than the specified interval, the latest value of your range will get pushed. So your pages will always be up-to-date.
