如果小于当前日期，则删除范围内的单元格

Question

I have a range of dates in plain text format (must stay this way) and I need to clear them at 1am if the date in each range cell is less than the current date. I can set up the run schedule later, but can anyone tell me why this isn't working?

I'm using =TEXT(TODAY(),"m/dd") to insert the current date in the correct format in cell AE3.

Thank you!

function clearOldDate() 
{

    var ss = SpreadsheetApp.getActiveSpreadsheet();  
    var sheet = ss.getSheetByName("Loads");
    var cells = sheet.getRange('AC9:AE33').getValues();
    var data = [cells];

    var date = sheet.getRange('AE3').getValues();
    //var Sdate = Utilities.formatDate(date,'GMT+0900','MM/dd');



    for(i=0; i<76; i++) 
    {


          if (date > data[i])
          {
              data[i].clear();  
          };
    };
 };

This should do the trick

function clearOldDate() 
{

    var ss = SpreadsheetApp.getActiveSpreadsheet();  
    var sheet = ss.getSheetByName("LogSheet");
    //getValues gives a 2D array. 
    var data = sheet.getRange('AC9:AE33').getValues();

    var date = sheet.getRange('AE3').getValues();
    //var Sdate = Utilities.formatDate(date,'GMT+0900','MM/dd');


    //This for loop with loop through each row
    for(i=0; i<data.length; i++) 
    {
          //This for loop with loop through each column
         for (var j = 0; j < data[i].length ; j ++){
          //This assumes Column AC has the dates you are comparing aganist
          if (date > data[i][j])
           {   
              //sets that the Row with index i to empty
              data[i] =  ["","",""]
           };
          }
    };
     //finally set the value back into sheet
     sheet.getRange('AC9:AE33').setValues(data)
     };

Basically, you need to setValues once data array is modified.

Note: This Statement (date > data[i][0]) doesn't work as expected when the values are stored as text.

Edit: Modified the code and added a new for loop to go through each column, based on comments
