Local tab migration

Import tabs into a local FreeSpace workspace.

Bring a portable tab list into FreeSpace without uploading its URLs or titles to a FreeSpace server. Preview accepted tabs, duplicates, unsupported records, and safety-limit truncation; inspect a tab sample and edit the workspace name before creating anything.

Plan disclosure: In a qualified supported region, import is available during an eligible PayPal-approved 30-day trial and the $1.99 USD/month base-price subscription that follows until canceled. FreeSpace shows the selected region, exact seller-collected tax, recurring total, and due-now amount for acceptance before it creates a PayPal subscription. Checkout is available to United States residents only. Local read, unlock, export, and delete access remain if entitlement ends.

Accepted formats

What FreeSpace can parse today.

Generic formats create one workspace from portable URL records. Documented Session Buddy JSON uses a dedicated, multi-workspace adapter with explicit fidelity limits.

Supported tab-list formats and fields preserved
FormatAccepted shapePreserved fields
Session Buddy v4 or v3 JSONDocumented collections/folders/links or sessions/windows/tabs object hierarchies.Multiple workspace names and order, tab titles and order, valid URLs, pins, safe embedded raster favicons, and named folder/window grouping.
OneTab 2.18 text or plain URLsOne URL per line, or URL | title lines. Exact multi-section OneTab text is recognized only when it contains at least one titled line.Valid URL, optional title, and input order in one workspace. Two or more importable blank-line sections become numbered Chrome groups; plain URL-only lists remain ungrouped.

Three steps

Preview first, then create.

  1. 1
    Export a supported file.

    Save a text, HTML, Markdown, CSV/TSV, generic JSON, or documented Session Buddy JSON export from your current tool.

  2. 2
    Choose Import tab list.

    Use Move from another tab manager in the command menu, or open the same action from Settings, then select the file.

  3. 3
    Review the preview.

    FreeSpace shows the detected format, accepted-tab sample, and accepted, duplicate, unsupported, and safety-limit counts. Generic imports have an editable workspace name; multi-workspace Session Buddy imports have selective workspace checkboxes.

Kept and normalized

URLs and useful titles.

  • The source filename supplies an initial workspace name that can be edited in the preview.
  • Valid HTTP, HTTPS, and local file URLs are accepted.
  • SPA route hashes beginning with #/ or #!/ are retained.
  • Common tracking parameters are removed and normalized URLs are deduplicated.
Not reconstructed

Proprietary product metadata.

Generic imports do not preserve vendor-specific hierarchy, groups, pins, notes, resources, collaboration state, or other fields unless they reduce to supported URL and title/name fields.

Documented Session Buddy v4 and v3 JSON gets a dedicated adapter. FreeSpace does not claim a branded Workona, Toby, TabXpert, or TABLERONE importer and is not affiliated with those products.

Safety and privacy

Bounded, local processing.

  • Maximum file size: 4 MB. Maximum imported tabs: 5,000. Session Buddy imports can create at most 200 workspaces.
  • Invalid, unsupported-scheme, credential-bearing, control-character, and overlong URLs are skipped.
  • JSON depth and record traversal are bounded to reject unexpectedly complex files.
  • File parsing happens in the extension. Tab URLs, titles, and file contents are not sent to the entitlement service.
  • If optional Chrome Sync is already enabled, the created workspace may be included in its next compressed backup.
