In my previous post (this post is the continuation of it) , I said that Tableau 8 introduced 130+ new features, 3 times more then Tableau 7 did. Tableau Forums Digest Weekly #4, #3 and #2 Richard Leeke’s Super-Charged ZIP Code Radius-Finder: Tableau Digest for 11/12 by Andy Cotgreave: Minard redone in Tableau (stupidity of french generals was the main reason, not a temperature, sorry Minard):ĭata Visualization course from Stanford University (Jeffrey Heer):ĭiscrete/blue and Continuous/green Fields in Tableau: (can you answer on the eternal question: to read or to write?)

Below is a link to a gist with the full code. So the general steps are: unzip packaged workbook > load in new data > create new data extract w/ API > replace extract > zip back up as a new packaged workbook. In addition to the Data Extract API, the sort of trick to this is that packaged workbooks are actually a different type of zip file. With Tableau Desktop you get access to the Tableau Data Extract API in Python. It's a great a language used in web applications, data analysis, office automation, and so on. If you're not familiar with Python it's worth looking into, it's a pretty intuitive programming language with powerful libraries for loading in data from csv, excel, MySQL, SQLite, APIs, etc. One approach is using Python and the Tableau Data Extract API to update the data extract for a packaged workbook (.twbx). Not good solution, but the best I have :( If you have Tableau on your actual machine, well, you need to make sure there's nothing there to mess with your script when you run it. I run Tableau Desktop on a virtual machine, and my script will only work if I'm actually logged in to the machine (otherwise it will not run the keyboard commands). It's not only a non-elegant solution, but a very unstable one too. twb file (if not already open), bring it to front, give an alt + d + x command (refresh all extracts), hit enter, wait for some time (in seconds, didn't figure out how to discover if the process is done), hit enter again, alt + f + k (export packaged workbook), some shift+tabs to go to folder prompt, enter the path, a few tabs to get to name prompt, enter the name, enter again, voila So I went to a non-elegant solution, used win32 api to make a script to give keyboard commands. twbx automatically (which is probably what you want to do. tde files, but yet you'll not be able to generate a. ![]() ![]() Extract data API can be used (with lots of effort) to update (replace). While I don't have it, I didn't find any "reasonable" solution for the problem. The final solution is going for Tableau Server. Have exactly the same problem, only I have to update hourly my database :) ![]()
