TWB - The Tableau Tools Ruby gem.

This gem provides a collection of classes to manage Tableau workbooks and their major components. It's the result of years of writing similar code.

Philosophy

Tableau Workbook governance should be:

• simple and straightforward in the way that basic data analysis is simple and straightforward in Tableau,
• free, as in beer and speech, and
• constantly evolving to incorporate new and interesting things people can think of to see about do with their Workbooks.

Tableau Tools are designed in the model of mini-tools, small independent tools that are individually useful and can be used together to accomplish broader tasks.

The gem is released to the Tableau community in the hope that it will prove to be useful and valuable, that people will build useful things with it, and that they will offer improvements and extensions to it.

History and rationale

A number of Ruby scripts that parse Workbooks and emit a variety of their contents/properties have been published at Tableau Friction, including a couple that identify Calculated fields and the fields they reference: http://tableaufriction.blogspot.ca/2015/02/more-calculated-field-analysis-fields.html http://tableaufriction.blogspot.ca/2014/09/do-you-know-what-your-calculated-fields.html

Other scripts find and record other useful information, still others enable Workbook management, e.g. unhiding worksheets and making field comments consistent across workbook. One of them produces HTML pages with dynamic dashboard wire frames, making it easy to see what's in the dashboards and their properties

Historical: TWIS - The Tableau Workbook Inventory System

There's also TWIS - the Tableau Workbook Inventory System, an application that parses workbooks and extracts most of their important elements into CSV files, allowing one to see things such as which sheets are in which with dashboards, the data sources they connect to, and which Workbooks they're in. TWIS also generates diagrams/maps of the Workbook - Dashboard - Worksheet - Data Source relationships, one for each Workbook in PDF, PNG, and SVG.

TWIS is described and available here: http://betterbi.biz/TWIS.html

TWIS is deprecated, no longer maintained

I created TWIS in Java, beginning in 2007. It was very valuable but became exceedingly difficult to maintain.
