Prevent Cells From Being Edited Based on Date - Google Sheets

Question

I am looking for a way to accomplish the following:

1) We have a Google Sheet where in Row A (Columns B-...) have dates, such as 10/30/18 in B1, 10/31/18 in B2, etc. We

Answer 1

I've tried to provide an answer based on some previously described approaches. Essentially, you create a protected range based on the date - we need to be aware that protection automatically applies to the full range, and we need to remove protection afterwards from dates in the future.

The below will be simpler, comparing only the date (and not time), locking cells with past dates. Under I mention an approach for date/time.

a = SpreadsheetApp.getActiveSpreadsheet();
  var s = a.getSheetByName('ExportPlan');
  var values = s.getRange("M1:M").getValues();
  var row, col, len, index; 

function mylockranges() {
  var myDate = TODAY(); //myDate is today

  //First range to lock
  var row = 1;
  var col = 1;


  for (row = values.length-1; row >=3 ; row--) {
    // Only unprotect rows with dates from today onwards
  if (typeof values[row][0] == 'object' && values[row][0] < myDate) {
    lockRange(row, col);

    }
  }
}

function lockRange(row, col){
  row = row+1 ; 
  var range = s.getRange(row, col, 1, 25);

  // Create protection object. Set description, anything you like.
  var protection = range.protect().setDescription('Protected, row ' + row);
}

For a date/time implementation, you can use myTime=NOW() for your date/time input. You can do addition on NOW() where adding 1 adds 1 day. Given that 70 minutes is roughly 0.0486 days, you can do something along the lines of if(NOW()< myTime +.0486) for your lock range. You can simplify this by using var allowedTime=NOW() + .0486 at the start.
