Web authoring improvements

These sound like small features, but they're the big hitters that stop power users from working — and fixing workbooks — entirely in the browser.

Watch on YouTube
  • You can now add highlight actions directly in the browser, though the highlighter legend can sit awkwardly under labels in a worksheet (a dashboard gives you more control to remove or reposition it).
  • Mark labels work as on desktop by holding Command/Control and dragging a field to Label, and you can control what gets labelled (e.g. only highlighted marks), but performance in the browser is noticeably slower.
  • Uploading a static Excel file keeps it as a live local connection rather than auto-converting to an extract; you create the extract from the top-right of the data source connection window, and it gets queued in the background.
  • Filters can now be applied to selected worksheets from a dashboard using the same Apply to Worksheets menu as Tableau Desktop, making proper dashboarding viable in the browser.
  • Fixed sets can be created by lasso-selecting marks on a map and choosing Create Set from the context menu; sets can't be edited, so to change one you reselect marks and add to or remove from it, or delete and recreate.

Tableau's 2020.4 web authoring update brings several desktop-only capabilities into the browser — highlight actions, mark label control, extract creation, cross-worksheet filtering from dashboards, and fixed sets — closing gaps that previously forced power users back to desktop for even minor fixes.

Tim works inside Tableau Online, editing a previously-built map, to demonstrate each new web authoring feature in turn.

The Breakdown
  • Add highlight actions in the browser 0:42

    You can now enable a highlighter directly on a worksheet in the browser, the same as on desktop. Watch out that the highlighter legend can land underneath mark labels with no way to reposition or hide it at the worksheet level; you get much more control once the sheet is placed on a dashboard.

  • Control what gets labelled 2:01

    Holding Command/Control while dragging a field onto Labels works identically to desktop, and the label options let you restrict labelling to specific conditions, such as only highlighted marks. Performance is noticeably slower in the browser than desktop when labels update, even on repeated selections.

  • Create an extract from a browser upload 3:41

    Uploading a static file like Excel does not automatically convert it to an extract — it stays a live local connection. To extract it, you must go into the data source's edit/connection window and use the extract option in the top right, not the right-click menu on the data source itself, which has no extract option.

  • Queue the extract and keep working 5:40

    Creating the extract queues it in the background with an elapsed timer and an optional notification when it's done; ticking the extract option without immediately clicking 'create' lets you carry on working while it processes rather than being kicked back to a finished-looking state.

  • Apply filters to selected worksheets from a dashboard 7:13

    Once a filter from one sheet is added to a dashboard, the filter's dropdown menu now offers an 'Apply to Worksheets > Selected Worksheets' option identical to desktop, letting one filter control specific sheets rather than needing workarounds. This is what makes proper multi-sheet dashboarding viable entirely in the browser.

  • Create fixed sets by lasso-selecting marks 9:17

    On a map or similar view, you can circle-select a group of marks and choose 'Create Set' from the context menu to fix that group as a set. Sets created this way can't be edited directly — to change one, you reselect marks and choose add-to-set or remove-from-set from the context menu, or delete and recreate it from scratch.

  • Why it matters for real work 10:54

    These look like small conveniences but remove the main blockers that used to force power users back to desktop, including fixing broken filters or workbook issues on the fly — even from a mobile device like an iPad.

Worth Knowing
  • The highlighter legend can sit under mark labels at the worksheet level with no way to move or hide it — you need a dashboard for proper control.
  • Mark label toggling is visibly slower in the browser than desktop, and doesn't reliably speed up even when repeating the same selection.
  • Uploading an Excel file to the browser keeps it as a live connection, not an extract, despite feeling like it should auto-convert.
  • Fixed sets created in the browser can't be renamed or edited in place beyond adding/removing marks — anything else means deleting and recreating.
Use It When

Reach for these when you need to fix or adjust a published workbook — filters, labels, sets — without opening desktop, including when you're only on a browser or tablet.

How this Rollup was made provenance & method

A Rollup is drafted by AI from the video's transcript, then reviewed and edited by Tim. Everything used to produce this one is listed below — the model, the exact prompt, and the source video — so the process is transparent and reproducible.
