How to find the right solution with loading data from google spreadsheets?

Question

PHP

Good day.
There are 140 google tables from which you need to get information from each active sheet with saving to a file ( file name = table name ) for further verification of changes, and if changes are found, then the telegram bot reports the line, column, changed text.
A script was written that conducts all the indicated manipulations, but only with 1 table . I am sitting for the second day and do not understand: how to process all tables correctly.

i would do like this:

element.onscroll = function (e) {
elem=e.target
  if (elem.scrollTop == 0)
    //с помощью CSS делаем тень СВЕРХУ
  else if (elem.scrollTop == elem.scrollTopMax)
    //с помощью CSS делаем тень СНИЗУ
}
