--please help me what iam doing wrong thanks in advance

I am not sure the GET string really wants HTML in it and in particular the equals signs in your data will look like valid GET string separators. I think you might want to send you data via POST. Perhaps you should look at jQuery and $jquery.post(). — Paul Coldrey

Activity on C# Corner (%) - "#" in this line is causing the problem. encoding this will resolve the issue in above code.

But its better to use POST as suggested.

If you pass html code via get then you must encode it else you can use post method. following code would be useful to you.

<script type="text/javascript">
 var htmlString= document.getElementById(allTables).innerHTML;
    $.ajax({
        type: "POST",
        url: "excel.php",
    dataType:'html',// ***add this option!***
        data: {html:htmlString},
        success: function (data) {
            // this is executed when ajax call finished well
             alert('file has been saved');
             location.reload();
        },
        error: function (xhr, status, error) {
            // executed if something went wrong during call
            if (xhr.status > 0) alert("Error: " + status); // status 0 - when load is interrupted
        }
    });
    }

</script>

Your excel.php file should be

<?php
  header('Content-Type: application/vnd.ms-excel');
  header('Content-disposition: attachment; filename='.rand().'.xls');
  echo $_POST["html"];
?>

and if you want to use $_GET then you should refer how can I javascript decodeURI in PHP? to encode and decode uri in javascript to php
