Save Developer’s Console Output as a File

You can create a save() method in the console object. From the Console window, you should be able to invoke the newly created method and pass the data that you wish to save. A popup window will prompt you to save the file.


(function(console){ = function(data, filename){

    if(!data) {
        console.error(' No data')

    if(!filename) filename = 'console.json'

    if(typeof data === "object"){
        data = JSON.stringify(data, undefined, 4)

    var blob = new Blob([data], {type: 'text/json'}),
        e    = document.createEvent('MouseEvents'),
        a    = document.createElement('a') = filename
    a.href = window.URL.createObjectURL(blob)
    a.dataset.downloadurl =  ['text/json',, a.href].join(':')
    e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
