问题
I tried using JSON.stringify(object)
, but it doesn't go down on the whole structure and hierarchy.
On the other hand console.log(object)
does that but I cannot save it.
In the console.log
output I can expand one by one all the children and select and copy/paste but the structure is to big for that.

Update: You can now just right click
Right click > Save as in the Console panel to save the logged messages to a file.
Original Answer:
You can use this devtools snippet shown below to create a console.save method. It creates a FileBlob from the input, and then automatically downloads it.
(function(console){
console.save = function(data, filename){
if(!data) {
console.error('Console.save: No data')
return;
}
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')
a.download = filename
a.href = window.URL.createObjectURL(blob)
a.dataset.downloadurl = ['text/json', a.download, a.href].join(':')
e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
a.dispatchEvent(e)
}
})(console)

In case you have an object logged:
- Right click on the object in console and click
Store as a global variable
- the output will be something like
temp1
- type in console
copy(temp1)
- paste to your favorite text editor

You can use the Chrome DevTools Utilities API copy() command for copying the string representation of the specified object to the clipboard.
If you have lots of objects then you can actually JSON.stringify() all your objects and keep on appending them to a string. Now use copy()
method to copy the complete string to clipboard.

There is an open-source javascript plugin that does just that - debugout.js
Debugout.js records and save console.logs so your application can access them. Full disclosure, I wrote it. It formats different types appropriately, can handle nested objects and arrays, and can optionally put a timestamp next to each log. It also toggles live-logging in one place.

You can use library l2i
(https://github.com/seriyvolk83/logs2indexeddb) to save all you put into console.log
and then invoke
l2i.download();
to download a file with logs.

There is another open-source tool that allows you to save all console.log
output in a file on your server - JS LogFlush (plug!).
JS LogFlush is an integrated JavaScript logging solution which include:
- cross-browser UI-less replacement of console.log - on client side.
- log storage system - on server side.

This is really late to the party, but maybe it will help someone. My solution seems similar to what the OP described as problematic, but maybe it's a feature that Chrome offers now, but not then. I tried right-clicking and saving the .log file after the object was written to the console, but all that gave me was a text file with this:
console.js:230 Done: Array(50000)[0 … 9999][10000 … 19999][20000 … 29999][30000 … 39999][40000 … 49999]length: 50000__proto__: Array(0)
which was of no use to anyone.
What I ended up doing was finding the console.log(data)
in the code, dropped a breakpoint on it and then typed JSON.Stringify(data)
in the console which displayed the entire object as a JSON string and the Chrome console actually gives you a button to copy it. Then paste into a text editor and there's your JSON
