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!

Yeah. It was Firefox. It works in chrome. Is there a way of having the file save dialogue with this like the load one so it's possible to name the file and decide where it will be downloaded to?

Both scripts don't work in Firefox. The first one does nothing but there are no errors. The second script returns a warning that it was prevented from running because there was no user interaction in Firefox. But they both work in edge and chrome. Just need the filebsave duologue for the save script.

For security reasons, I Don't think there is an easy way of having the file save dialogue to save the file (disclaimer: I am not an expert in javascript/browsers). You better download the file and then move it.

You can do it, but for some bizarre reason you can't call the function with a button. It has to be called with <input type "file" which gives you a file picker but then if you assign the load function to it, you get the file picker dialogue twice. It's just another weird thing that the drug addled creators of HTML and JavaScript designed to make us suffer.
