Export Your Arc Tabs & Spaces to Bookmarks

Load Arc's StorableSidebar.json and recover saved Spaces, pinned tabs, and URLs into a standard bookmarks file.

Runs entirely in your browser. Nothing leaves your device.

Recover Arc tabs from StorableSidebar.json

Where to find it:
macOS: ~/Library/Application Support/Arc/StorableSidebar.json
Windows: %LOCALAPPDATA%\Packages\TheBrowserCompany.Arc_ttt1ap7aakyb4\LocalCache\Local\Arc\
Drop StorableSidebar.json here Click to choose a file, or paste copied JSON while this box is focused.
Arc doesn't publish how this file is organized, so this tool first looks for named Spaces, then falls back to finding any links in the raw text.

How it works

  1. Find Arc's StorableSidebar.json file and make a copy before opening it here.
  2. Drop the copied file into the converter, or paste the JSON text.
  3. The tool looks for saved Arc links and Space titles without assuming one fixed file layout.
  4. If it can't find named Spaces, it extracts every http or https link it can find and tells you the folder structure was not recovered.

Rescue Arc Spaces before they become stranded

Arc did not include a normal bookmark export button, which makes leaving Arc more awkward than it should be. The useful data is often inside a local file named StorableSidebar.json. This page reads that file in your browser and converts recoverable saved tabs into a standard bookmarks HTML file.

Arc doesn't publish how this file is organized internally, and the layout can shift between versions. Instead of relying on one fixed path, the converter searches through the whole file looking for saved links and titles. When it can identify Space titles, those Spaces become bookmark folders.

If that search finds nothing, the tool falls back to finding raw links in the file's text. That is less tidy, but it is better than losing the links entirely. You will see a clear message when this happens: recovered links without folder structure.

Arc development stopped in May 2025 as The Browser Company pivoted to Dia. If you are landing back in Chrome, make a boring portable backup first, then decide what should become bookmarks, saved tab groups, or a fresh workspace.

Frequently Asked Questions

Where do I find StorableSidebar.json?
On macOS, look in ~/Library/Application Support/Arc/StorableSidebar.json. On Windows, check %LOCALAPPDATA%\Packages\TheBrowserCompany.Arc_ttt1ap7aakyb4\LocalCache\Local\Arc\. Copy the file somewhere easy to find, then drop the copy into this page.
Is Arc really discontinued?
Arc development stopped in May 2025 when The Browser Company shifted focus to Dia. Existing Arc installs may still run, but the lack of a normal export button makes a local backup smart. This tool is meant for that rescue step.
Will my Spaces become folders?
When the file makes Spaces identifiable, each Space becomes a bookmark folder. If Arc has changed the file's layout too much to recognize, the tool falls back to recovering raw links from the text and clearly tells you that folder structure was not available.
Does this touch Little Arc or history?
No. The page only reads the file you choose and looks for saved tab URLs inside it. It does not connect to Arc, inspect browser history, or modify your Arc profile.

Landing back in Chrome?
