Ask Data and Slack integration: New in Tableau 2021.4

Ask a question in plain English, get a chart, then ping it straight to a colleague on Slack.

  • Tableau 2021.4 lets you send Ask Data notifications to Slack as well as email, provided notifications are enabled
  • Ask Data now requires a lens before you can ask a question, so you need one set up first
  • You type a natural-language question (like 'busiest day in 2018') and Tableau interprets it into a chart you can refine
  • Sharing a result sends it to multiple destinations at once, and recipients can continue the analysis from where you left off
  • Notification links contain a hidden ID that is removed after viewing, likely to stop them being endlessly reshared

Tableau 2021.4 lets you ask a natural-language question in Ask Data and push the resulting chart straight to a colleague via Slack (as well as email), so insights can be shared and continued by someone else without leaving the flow.

Demoed using two Tableau Online profiles: one admin sending the notification, one user receiving it in Slack, to show both sides of the interaction.

The Breakdown
  1. Start from an Ask Data lens 0:21

    You must have an Ask Data lens set up first, since Tableau now requires a lens before it will let you ask a question — go to the Explore tab and pick or create one.

  2. Type a plain-English question 0:41

    Type a natural-language question like 'busiest day in 2018'; Tableau translates it into a structured query and returns a chart, which may need a bit of refining if it misreads your intent.

  3. Share the result to Slack and email at once 1:21

    Hitting Share from an Ask Data view sends the result to multiple destinations simultaneously — Slack and email notifications — as long as notifications are enabled for the recipient.

  4. Add a message and pick the recipient 1:40

    When sharing, you type a short message and choose the specific user profile to send to; this only reaches people set up to receive Tableau notifications in Slack.

  5. Recipient opens the link while logged in 2:22

    The Slack notification links back to the exact Ask Data view; the recipient needs to be logged into their own Tableau account to open it and see the shared analysis.

  6. Recipient can continue the analysis 2:41

    Once opened, the recipient isn't just viewing a static chart — they can carry on asking their own follow-up questions from where the original person left off.

  7. Notifications also land in Tableau's own inbox 3:01

    The same shared notification also appears in Tableau's in-product notifications area (not just Slack/email), giving another route back to the shared view.

Worth Knowing
  • Ask Data now requires a lens before you can ask any question at all — this is a prerequisite, not optional
  • Sharing only reaches someone via Slack if that user has Slack notifications enabled and is set up as a Tableau user with a linked Slack account
  • The recipient must be logged in as themselves to open the shared link — it isn't a generic public link
  • The hidden ID in the notification URL disappears after use, seemingly to stop links being freely reshared
Use It When

Reach for this when you spot something interesting in an ad-hoc Ask Data query and want to flag it to a colleague immediately, letting them pick up and extend the same analysis rather than just sending a static screenshot.
