Google Workspace Add-ons for Small Business (2026): 9 by Job

Small teams lose hours every week copying numbers into spreadsheets, forwarding emails to each other and guarding diary space by hand. Google Workspace add-ons can take a lot of that off your plate, as long as you pick by the chore rather than by the logo.

So I've sorted nine add-ons by the Workspace app they live in and the job they do there. They come from each vendor's own pages, they're in no particular order, and anything a vendor says about itself is labelled as its claim.

Your admin may have to say yes first

Here's the thing that trips most small businesses up. An add-on only works if the person installing it has permission to. Slack's own help page says that if you can't install its Gmail add-on, a Google Workspace administrator has to approve it in the Admin Console. That pattern applies across business domains: whoever runs admin decides which add-ons people can use.

Each add-on also asks for access to your mail, sheets or calendar when you connect it, and that request is worth reading. A personal Gmail account has no admin gate at all, which is why a tool that worked on your home account can be blocked on the company one. If you're the owner and the admin, give yourself ten minutes to check the settings before you roll anything out.

Which Workspace app each add-on lives in

Tool	Workspace app and job	Good for
Ablebits	Sheets clean-up, Gmail templates	Duplicates, text case and merged data in spreadsheets
Asana	Gmail: tasks	Turning emails into tasks from the Gmail sidebar
Awesome Table	Sheets: data onto a website	Pulling HubSpot, Zendesk or Stripe data into a sheet
Coupler.io	Sheets: scheduled imports	Scheduled data imports from other apps into a sheet
Reclaim	Calendar: planning and focus time	Fitting tasks, habits and focus time round meetings
Sheetgo	Sheets: data automation	Moving data between spreadsheets and business systems
Slack	Gmail: team chat	Sending emails into team channels and conversations
Supermetrics	Sheets: marketing data	Ad and marketing reports that refresh on their own
Yet Another Mail Merge (YAMM)	Sheets and Gmail: mail merge	Personalised emails from a sheet, sent from your Gmail

Sheets: reports, clean-up and mail merge

Most of the add-ons here live in Sheets, because that's where small businesses do their reporting. Coupler.io imports data from other apps on a schedule, and Supermetrics does the same for marketing and ad data, with reports that refresh themselves. Sheetgo moves data between spreadsheets and other systems, while Awesome Table pulls data in and shows the sheet on a website.

For clean-up, Ablebits sells a family of separate Sheets add-ons for jobs like removing duplicates and merging data, and one Gmail add-on for shared email templates. For mail merge, Yet Another Mail Merge sends personalised emails from your Gmail using a sheet. If mail merge is your main job, our round-up of Gmail mail merge tools goes further.

Gmail and Calendar: tasks, team sharing and focus

In Gmail, Asana turns an email into a task and lets you work on tasks from the sidebar. The team chat add-on in the table sends emails into your channels so colleagues see them without a forwarding chain. In Calendar, Reclaim plans tasks, habits and focus time around your meetings.

Add-ons and Chrome extensions aren't the same thing

Workspace add-ons install from Google's own Workspace app directory and open in the side panel of Gmail, Sheets or Calendar, while Chrome extensions install in your browser. The difference matters because admins control the two in different places. If a browser tool is what you're after, our guide to Chrome extensions for Gmail covers that side.

All nine add-ons, in no particular order

Ablebits

Best for: Spreadsheet tidying through separate add-ons such as Power Tools, Merge Sheets and Remove Duplicates, plus a Gmail add-on for shared email templates.

Asana

Best for: Teams who plan work in a task manager and want to turn an email into a task, then search, comment on or complete tasks without leaving Gmail.

Awesome Table

Best for: Showing spreadsheet data on a website: it imports from sources such as HubSpot, Zendesk and Stripe, with connectors the vendor says only work in its Sheets add-on.

Coupler.io

Best for: Anyone rebuilding the same spreadsheet by hand each week: it imports data from other apps on a schedule, set up from its web app or inside the sheet.

Reclaim

Best for: Protecting focus time: it schedules tasks, habits, breaks and focus blocks around your meetings in Google Calendar, and the vendor says it works with Outlook Calendar too.

Sheetgo

Best for: Small teams linking several spreadsheets and business systems, with its Automations product run from a Sheets add-on or the web app (vendor description).

Slack

Best for: Sharing an email with colleagues without a forwarding chain: it sends Gmail messages into team channels or conversations straight from the sidebar.

Supermetrics

Best for: Marketers reporting on ads: install the add-on, choose a connector such as Facebook Ads, run a query, and the vendor says reports then refresh automatically.

Yet Another Mail Merge (YAMM)

Best for: Sending personalised emails from your own Gmail using a sheet, with follow-ups, and opens, clicks and replies written back into the same sheet (vendor claim).

My advice for small teams adding add-ons

Pick the one chore that eats the most time each week and install a single add-on for it. Live with it for a fortnight before you add another, because every add-on is another set of permissions on your data and another thing to remove when someone leaves. Start in Sheets if your pain is reporting, and in Gmail if it's emails falling between people.

If you're the admin, make a short allow-list of approved add-ons and tell your team it exists. It's quicker than approving requests one at a time, and it stops people quietly using personal accounts to get around the block.

Why there's no Docs add-on here

You'll notice Docs has no entry. I couldn't confirm a vendor Docs add-on from the vendors' own pages, so rather than guess, I've left that app out. Docs add-ons do exist, but check each one's own page and the permissions it asks for before you install it.

Frequently asked questions

What is a Google Workspace add-on?

It's a small app that runs inside Gmail, Sheets, Calendar or another Workspace app, usually in the side panel. You install it from Google's Workspace app directory and connect it to your account.

Why can't I install an add-on at work?

On a business domain, your Workspace admin may have restricted add-ons. They can approve the one you need in the Admin Console. Personal Gmail accounts don't have this gate.

Are Workspace add-ons safe to use?

Each add-on asks for access to your data when you connect it. Read what it requests, install only what you need, and remove add-ons nobody uses any more.

What's the difference between an add-on and a Chrome extension?

An add-on lives inside a Workspace app and installs from Google's app directory. A Chrome extension lives in your browser. Admins manage them in different places.

Which Workspace app has the most useful add-ons for small businesses?

For many small teams it's Sheets, because reporting, data imports, clean-up and mail merge all happen there. Gmail add-ons help most when emails need sharing or turning into tasks.

Can I use Workspace add-ons with Microsoft 365 too?

Add-ons are built for Google Workspace, though some vendors also offer versions for Microsoft apps. If you're still choosing a suite, compare the two suites on the apps your team uses every day.
