Export OneTab to another tool

1. Export from OneTab

1. Click the OneTab icon, or open the OneTab page from the extensions menu (the puzzle icon) if you've hidden it.
2. Choose Export / Import URLs. Depending on your version it sits at the top right of the page or in OneTab's menu.
3. The export box shows every saved tab, one per line, in the form https://example.com/page | Page title. A blank line separates the groups you saved at different times.
4. Click into the box, press Ctrl+A (Cmd+A on Mac), then Ctrl+C.
5. Paste into a plain text editor (Notepad, TextEdit in plain-text mode, VS Code) and save it as onetab-export.txt.

Check the end of the file: if you have thousands of tabs, make sure the last group made it into the paste.

2. What the export keeps, and what it drops

• Kept: every URL, its title, and the grouping (as blank lines).
• Dropped: group names, the date each group was saved, and starred or locked flags. If group names matter, write them down or rename the groups in your new tool after importing.

3. Bring it into another tool

The text format is simple enough that you have options:

• A tab manager with a OneTab importer (Tabkeep has one) reads the file as is and keeps the groups.
• Bookmarks: open a group with OneTab's Restore all, then press Ctrl+Shift+D (Cmd+Shift+D on Mac) to bookmark all open tabs into a new folder. Repeat per group.
• Another OneTab: on a new computer, paste the same text into Export / Import URLs → Import.

Keep the file

Even after you've switched, keep onetab-export.txt somewhere that's backed up. It's a complete, readable record of your saved tabs that doesn't depend on any extension.
