How to export content in Chrome's local storage for a website

LocalStorageExport.md

Original idea is from this post

1. Open a tab and navigate to the website where you have content to export.

2. Open devtools and switch to the console tab.

3. Copy and paste the following snippet in the console and Chrome should ask you to save the output file

var obj = JSON.stringify(localStorage, null, 4)
var vLink = document.createElement('a')
vBlob = new Blob([obj], {type: "octet/stream"})
vUrl = window.webkitURL.createObjectURL(vBlob);
vLink.setAttribute('href', vUrl);
vLink.setAttribute('download', vUrl.split('/')[2] + '-export.json'); // give you the website name + "export.json"
vLink.click();

4. Profit!

I tried to use this to transfer my telegram web to another machine. The script worked fine, but telegram detected the tampering and logged me out :(
A note for others that may try to do something similar to this
