Import and export

Import brings tabs, bookmarks, and history from another browser into Sval. Export saves your Workspaces and Favorites for another browser, or everything Sval keeps as plain JSON.

Settings › Workspaces › Import and export

Section titled “Settings › Workspaces › Import and export”
  • Import data opens the import dialog.
  • Export data opens the export dialog.
  • Export all Sval data opens the export dialog on Sval (complete data): Workspaces, Favorites, history, and settings from this device, unencrypted.

In the menu bar, File › Import From Another Browser… opens the import dialog too.

The import dialog

Section titled “The import dialog”

The dialog lists the browsers it finds on this computer, one row each, however many profiles a browser has. It can read Chrome, Edge, Brave, Vivaldi, Arc, Dia, Safari, Orion, Firefox, and Zen. The browser you used last starts checked.

  • A browser’s row shows what it holds, like the number of Workspaces, tabs, and bookmarks. Checking it opens its choices, and the arrow folds them to one line that says what will import.
  • Import a bookmarks file… adds a row for a bookmarks HTML file, or for the Arc Data Export.md file Arc’s data export makes.
  • Workspaces lists each profile, Space, Workspace, or Tab Group the browser holds. Each has a checkbox, a name you can change, Isolated, and a count of its tabs that shows a preview of them.
  • Isolated gives the new Workspace its own cookies and sign-ins.
  • Choose how to import the browser’s bookmarks: Into Favorites, into a Workspace of their own with a name you give it, or Don’t import.
  • Also import history from the browser brings its recent history.
  • Archive tabs you haven’t used, like Arc did shows for Arc. It turns on Archive idle tabs with the time Arc used, which you can change next to it.
  • Move your passwords to your password manager shows when a checked browser has saved passwords. Sval doesn’t import passwords. Show steps lists how to export them from that browser and import them into your password manager.
  • Open System Settings shows for Safari until Sval has Full Disk Access on your Mac.
  • Import imports what’s checked. Cancel closes the dialog.

While the import runs, the dialog shows each browser’s progress. When it ends, it says what arrived, with Done to close it. A browser that failed gets its own line, with Try Again, Import Bookmarks File…, or Send Report….

When you first set up Sval, the Import from another browser step offers the same choices.

The export dialog

Section titled “The export dialog”
  • The browser you’re moving to lists Chrome, Edge, Brave, Vivaldi, Opera, Arc, Dia, Firefox, Zen, Safari, Another browser, and Sval (complete data).
  • What to export lists your Workspaces, each checked, then Favorites. For Safari, History shows too. Agent Workspaces aren’t listed.
  • Export… asks where to save the file. Once it’s saved, the dialog says where to import the file in the browser you chose, with Done to close it.
  • Cancel closes the dialog.

Each Workspace becomes a folder of bookmarks, and Favorites go to the new browser’s favorites bar. Sval (complete data) saves a ZIP of plain JSON with a README, and includes no key.
