FAQ

Q: What is Tableau Public?

Tableau Public is a free service that lets anyone publish interactive data to the web. Once on the web, anyone can interact with the data, download it, or create their own visualizations of it. No programming skills are required. Be sure to look at the gallery to see some of the things people have been doing with it.

Q: Who is Tableau Public for?

Tableau Public is for anyone interested in understanding data. Writers, bloggers, students, professors, hobbyists, journeymen, critics, citizens and more. It’s also meant for organizations, but only as an introductory service. If your organization wants to put data online for the public, you are welcome to explore what Tableau has to offer via Tableau Public. If you like what you see, contact us at public@tableau.com to discuss a commercial relationship.

Q: How does Tableau Public work?

Tableau Public combines a free version of our data visualization app (Tableau Desktop) with a free version of our cloud-based server service (Tableau Online). Use Tableau Desktop Public Edition to explore your data and save it to your profile on Tableau Public. You can then share and/or embed your visualizations (we call them vizzes) from there. Everything saved to Tableau Public is accessible by anyone on the internet, so be sure to post only with publicly available (and appropriate) data.

Q: I have my own blog or website. Can I use Tableau Public to share data there?

Yes. Use Tableau Public to share data and insights with your community. Embed the content in your blog or website, or share it via links on web pages or in emails.

Q: How much storage space do I get?

We provide ten gigabytes (10 GB) of storage space for your workbooks (aka. vizzes).

Q: Do I need to know code to use this stuff?

No programming skills of any kind are required to use the app or the site. You'll need to have some basic HTML skills in order to embed your viz on a website, but we make that as easy as possible by providing you all the HTML necessary for the embed itself.

Q: I work for an organization that has lots of data to share with the public. Can we use Tableau Public?

Yes — so long as you and everyone in your organization together use less than 50 megabytes of space. Tableau Public gives your organization (e.g., a company, government agency or educational institution) the opportunity to explore its capabilities. If your organization wants to put data online for the public, please contact us at public@tableau.com to discuss a commercial relationship.

Q: Do I need to use Tableau Desktop (Public Edition) if I already own a commercial version of Tableau Desktop (Personal or Professional)?

Nope! Tableau Desktop comes in three editions: Public, Personal, and Professional. All of them work with Tableau Public.

Q: What kind of data can I use?

Tableau Desktop (Public Edition) works with data from Microsoft Excel, Microsoft Access, and multiple text file formats.

Q: Are there any limits to the amount of data I can work with?

Tableau Desktop (Public Edition) is limited to 10,000,000 rows of data per workbook.

Q: Can I set permissions or protect the data I save to Tableau Public?

All content saved to Tableau Public is accessible to everyone on the internet. As the author, you are the only one who can delete your own content, but anyone on the internet can view it. In addition to viewing it, anyone can download a copy of your workbook (including the underlying data) as well, which will let them work with and build upon your original.

Q: If I publish my data on Tableau Public, is my data now public?

Yes, the workbook you publish to Tableau Public using your data is now viewable by anyone on the world-wide web. You aren’t able to prevent others from accessing your workbook, sharing it via social media, or downloading it in various formats including images, pdfs, or, unless you disable it, the full workbook itself. If you intend to share proprietary data on the web and want to control who has access to it, we suggest you consider using Tableau Online.

Q: What blog services is Tableau Public compatible with?

Embedding Tableau Public content requires support for embedded html content, including script tags. Compatible blogs include

  • Blogger by Google (blogger.com)
  • Typepad (typepad.com) – Make sure to edit your posts in HTML mode rather than Rich Text, otherwise the Tableau Public embed codes don’t get preserved.
  • Wordpress (wordpress.org) – WordPress is completely customizable and can be used for almost anything. Web host required.

Q: What kind of technology is a Tableau viz?

A Tableau viz is essentially an AJAX-based JavaScript application.

Q: How do people find the visualizations I've saved to Tableau Public?

Once you save your work to Tableau Public, it may be shared (by emailing a link or embedding the work in your blog, wiki, or website). If you embed the work onto a webpage, anyone who visits the page will see the live interactive view. If you email a link, just clicking the link will open a browser page with the view loaded.

Q: What’s the "Download" link on the viz?

Any Tableau Public viz can be downloaded by pressing the download link in the lower right corner. It saves to your computer as a TWBX file. Anyone with Tableau Desktop (Professional, Personal or Public Edition) can open the file and review or extend the work that was behind the original posting. You can disable the ability to download the workbook in the viz settings.

Q: Are any plug-ins required to view a Tableau viz?

No plug-ins are required. All you need is a web browser with JavaScript enabled.

Q: What happens if I delete a workbook from Tableau Public and there are links to it in blogs or other web locations?

Once a workbook or view is deleted from Tableau Public, it cannot be retrieved from Tableau Public by anyone. All links or other references to it that may have been shared will not be able to load the viz and will display an error message on the page.

Q: What are the system requirements for the desktop software?

Check out our product page for complete specs and system requirements.

Q: Is Tableau Desktop (Public Edition) available for Mac?

Yes! Version 8.2 (and up) work with OS X. Download the latest version and give it a try.
