Download & install

In your ribbon in about two minutes.

Tellsheet installs from inside Excel — no separate download, no installer wizard, no admin rights on most setups. Here’s the whole process.

1

Open Excel and find the add-in store

In Excel, go to Home → Add-ins (or Insert → Get Add-ins on older versions). This works the same on Windows, Mac, and Excel on the web.

2

Search for “Tellsheet” and add it

Type Tellsheet in the search box, click Add, and accept the permissions prompt. A Tellsheet button appears on your Home ribbon. If your organization manages add-ins centrally, forward our admin guide to your IT team — sideload manifests are available.

3

Enter your license key

Click the Tellsheet button, open the panel, and paste the license key from your purchase email. That’s it — all 21 tools and the command bar are live. Don’t have a key yet? Get Tellsheet for $39, or try the tools first and buy when you’re convinced.
