With my very basic knowledge I have compiled the following function to save a html-table as .json file. This function works very well and quick as long as the html table is not filtered.

function invent2JSON(fname) {
    var table = document.getElementById("myTable");
    var header = [];
    var rows = [];
    var totalsObj = {rows};
        
    for (var i = 0; i < table.rows[0].cells.length; i++) {
        header.push(table.rows[0].cells[i].innerHTML);
    }
 
    for (var i = 1; i < table.rows.length; i++) {
        var row = {};
        for (var j = 0; j < table.rows[i].cells.length; j++) {
            row[header[j]] = table.rows[i].cells[j].innerHTML;
        }
        rows.push(row);
    }
 
        
        
    var myBlobFile = new Blob([JSON.stringify(totalsObj,null,2)], { type: 'text/json;charset=utf-8' });
    
    var url = window.URL || window.webkitURL;
    
    var temp_link = document.createElement('a');
    temp_link.download = fname+".json";
    temp_link.href = URL.createObjectURL(myBlobFile);
    //temp_link.hidden = true;

    

    // This link should not be displayed
    
    document.body.appendChild(temp_link);
    temp_link.click();
    document.body.removeChild(temp_link);
        
        
    }

As soon as I apply the filter function ddtf.js (ddtf.js) to the html table and try to export the html table again as .json file I get an error message indicating that there is a Uncaught RangeError: Invalid string length. This error happens exactly at this line of the export function

var myBlobFile = new Blob([JSON.stringify(totalsObj,null,2)], { type: ‘text/json;charset=utf-8’ });

I really don’t get the point why I get this error message. Anyone around who has an idea? I thank you very much in advance.
