Office Tab: Browser-Style Tabs for Word, Excel and PowerPoint
Office Tab is a $39 one-time-purchase Windows add-in from ExtendOffice that opens Word, Excel and PowerPoint files as tabs in a single window, for anyone who keeps many documents open at once.
Every Office file normally gets its own window, so a busy afternoon ends with a taskbar full of near-identical icons. Office Tab brings the way your browser works to Office, and it's one of those changes you stop noticing until you're on a computer without it.

Overview
Office Tab adds a tab bar under the ribbon and an Office Tab ribbon tab for its settings. ExtendOffice says it uses standard Office add-in technology and has more than 900,000 users. The product dates back well over a decade, and it's still maintained, with version 19.00 arriving in July 2026 after 18.00 in April 2025.
Office Tab is the standard edition. Office Tab Pro adds the same tabs to Publisher, Access, Project and Visio. ExtendOffice no longer sells separate Tabs for Word, Tabs for Excel or Tabs for PowerPoint products, because all three are part of this one.
Features
Open files as tabs in one window
Office Tab puts every open document on a tab bar in a single window, like a web browser. You switch with a click or with Alt + N, and drag tabs to reorder them.
Color-coded tabs across the top of an Excel window, switching between open reports.
Save or close everything at once
Office Tab adds Save All and Close All commands to the tab menu, so ending the day doesn't mean a dozen separate prompts. You can also rename a file right from its tab, without the Save As dialog.
Group documents by project
Office Tab lets you collect files into groups, then open, save or close a whole group together. That's handy when a job always involves the same five files.
Make the tabs look the way you want
Office Tab offers new and classic tab styles, color-coded tabs, custom fonts, and fixed, adaptive or automatic tab lengths. The newer layout shows two lines of text, so long file names stay readable.
Put the tab bar anywhere
Office Tab can place the bar at the top, bottom, left or right of the window, and hide or show it with a shortcut, which defaults to Win + Q. Other shortcuts can be changed too.
Three documents on tabs in Word, shown with an older Office look.
The same tab bar in PowerPoint.
Benefits
You lose less time hunting. When twelve Excel files are open, the taskbar shows twelve green icons, while a row of named, colored tabs shows you where everything is. Fewer windows also means fewer cases of editing the wrong version of a file.
The Close All and Save All commands are a small thing that adds up, especially at the end of the day. And since tabs behave like a browser's, nobody needs training.
Real-World Uses
- Monthly reports: keep twelve workbooks open and color each quarter differently.
- Contract work: group the agreement, schedules and cover letter, then open or close them together.
- Copying between decks: flip between PowerPoint files without losing your place on the taskbar.
- Laptop screens: keep one maximized window with tabs when you have no room for side-by-side windows.
Who It's For, and Who Should Skip It
Office Tab suits people who regularly have five or more Office files open on Windows: analysts, lawyers, admins and project staff.
Skip it if you usually work in one file at a time, since there's nothing for it to organize. Skip it on a Mac, where it doesn't run, or if you do most of your work in Office on the web. And if you live in Publisher, Access, Project or Visio, get Office Tab Pro instead. To tab windows across every application rather than just Office, tools such as TidyTabs or Stardock Groupy fit better.
Usage Guide
- Close your Office programs and run the installer.
- Open Word or Excel. New documents now open as tabs in the same window.
- Right-click a tab to find Save All, Close All, Rename and tab colors.
- Open the Office Tab ribbon tab to change the style, position and shortcuts.
- To update later, uninstall the old version from the Control Panel first, then install the new one.
Before you buy
- Pick the right edition. Moving from Office Tab to Office Tab Pro later means emailing sales@extendoffice.com with your order details.
- Lifetime means the version you have. Updates and support stop after two years unless you renew at a discount. Since new Office builds can break add-ins, consider renewing if you're on Microsoft 365.
- No free edition. Older listings mention one, but ExtendOffice now offers only the 30-day trial.
Where it falls short
- Office updates can break it. ExtendOffice's own notes for version 16.00 say a Microsoft Office upgrade had disabled the Word tab feature until that release fixed it. That's the risk with any add-in, and it's a good reason to keep update coverage current.
- Occasional crashes are a documented issue. ExtendOffice keeps a support page on Office crashes linked to tabbed windows. Its advice is to update Office Tab, disable other add-ins and check any desktop-management tools, which can conflict with it.
- Small quirks exist. See the Visual Basic Editor taskbar snag in the user comments below, which matters mainly to people who write macros.
- The screenshots lag behind the product. Much of the vendor's gallery still shows an older Office look, so the trial is the better preview.
What Users Say
Recent independent reviews of Office Tab are few, but they're consistent.
Trustpilot
Trustpilot, ExtendOffice company page: 4.3 out of 5 from 8 reviews when we looked on November 6, 2026. That's a small sample, and it covers the company rather than this one product.
Vaibhav, "I have been using ExtendOffice tools", 5 stars, August 5, 2026, on Office Tab: "Excellent software and great customer service." He mentions a discount and help getting a new license key after reformatting.
Jesse Crenshaw, 5 stars, May 7, 2026, a retired banking analyst, has bought Office Tab products alongside Kutools and praises the no-subscription pricing and the support team.
Terry Bradley, 1 star, July 16, 2022, on recovering licenses after a machine failure: "It is a long and drawn out and impossible process to try and retrieve your very long serial code." He adds "I regret having purchased." ExtendOffice answered in May 2026 with an apology.
Microsoft Tech Community forum
Charles_Kenyon, January 18, 2023, answering a question about whether Office Tab is safe: "Like all third-party tools, it could break when Word is updated." He later adds: "It works in my installation and they offer a free trial."
He also reports one snag: "One minor drawback I have noticed involves use of the visual basic editor". With the add-in installed, clicking the editor on the taskbar takes you to the document instead, so "You must use Alt+F11 to switch to the vbe even if already open." His view: "For most users, this would not even be noticed."
AlternativeTo
Shoji VR, January 17, 2018: "Each document appears as a new tab in a tabbed window (not a new window) and can be accessed in one click."
A user writing on April 7, 2015: "I like this BUT the description says it is Free for personal use. It's not." Today ExtendOffice offers a trial, not a free edition.
Customers quoted by ExtendOffice
George: "Ku Tools for Word, Ku Tools for Excel, and Office Tabs are the very best tools in my software library. I use them every single day". ExtendOffice shows this on its own site, so treat it as hand-picked.
The pattern: people who install it tend to keep it for years, and the complaints are about licensing and small side effects, not the tabs themselves.

Conclusion
Office Tab is worth $39 if you regularly juggle several Office files on Windows. It does one thing, it does it in a way anyone can use, and it's been maintained for many years.
The reason to buy is a calmer screen and fewer wrong-window mistakes for a one-time $39. The reason to pass is that it's an add-in that sits in the middle of Office, so an Office update can occasionally trip it up, and one-file-at-a-time users get nothing from it.
