What is Lexicon?

Lexicon is a data dictionary that lets you store event descriptions for everyone in your project to see. It surfaces them in Insights, Segmentation, Funnels, and Retention, so your team can pull the right data and answer product questions with confidence. Lexicon is available on all paid plans.

Lexicon is located in your Applications folder, it looks like this!

Add an event description

All events in your project automatically appear in the dropdown menu. When you add a description (up to 170 characters) to an event, it will be temporarily tagged with a yellow triangle and have an unverified status. Click the big play button below to see it in action!

Verify an event description

Verification helps you distinguish valid and accurate events from invalid or inaccurate ones. We suggest verifying events only after you've confirmed they are being sent correctly. Only Owner or Admin team members can verify event descriptions. And if necessary, click the same icon to unverify!

Where do event descriptions appear?

Event descriptions show up inside Lexicon and throughout your reports. They appear in two ways:

  • Unverified descriptions: Display the event description only
  • Verified descriptions: Also possess green event icons, the verifier name and the date of verification.

Check out the video to see how it works!

Delete an event description

Deleting an event description will remove it for everyone in the project. If you want to change the description you can edit it by clicking directly on the text!

Can properties have descriptions?

Lexicon allows you describe events only. We suggest mentioning key properties in your event description to remind you and your team what to filter by. You have 170 characters, make it count!

Which Team Member Roles can use Lexicon?

Both default team roles (Owner and Admins) can add, edit, verify, and delete Event Descriptions.

If you have Team Member Roles, the Analyst and Consumer roles can only view the Event Descriptions. They cannot add, edit, verify, or delete them.

Some events have descriptions already? Where did those come from?

Mixpanel will create events for common mobile events, notifications, page views, A/B tests and more! Here are the Default Event Descriptions for events created by Mixpanel. Enjoy!
