I\'ve read and even used code for treating dat

Answer 1

For the ShowColumns() script, are you just needing to unhide all columns in the sheet? If so, you could at least simplify that one a bit:

function ShowColumns() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getActiveSheet();
  var range = sheet.getRange("1:1");
  sheet.unhideColumn(range);
}

Answer 2

unfortunately hiding columns is a "spreadsheet only" function, no way to make it faster or in batch...

maybe you could imagine a custom UI (built with UiApp or HTMLService) to show only the user relevant data ? but that might not be possible, depending on how much you need spreadsheet specific features..., not speaking of the work it might represent.
