This repo contains Python source and example files for the Tableau Document API. We're just getting started and have plans to expand what you find here. Help us by submitting feedback, issues, and pull requests!
The Document API provides a supported way to programmatically make updates to Tableau workbook and data source files. If you've been making changes to these file types by directly updating the XML--that is, by XML hacking--this SDK is for you :)
Features include:
- Support for 9.X, and 10.X workbook and data source files
- Including TDSX and TWBX files
- Getting connection information from data sources and workbooks
- Server Name
- Username
- Database Name
- Authentication Type
- Connection Type
- Updating connection information in workbooks and data sources
- Server Name
- Username
- Database Name
- Getting Field information from data sources and workbooks
- Get all fields in a data source
- Get all fields in use by certain sheets in a workbook
We don't yet support creating files from scratch, adding extracts into workbooks or data sources, or updating field information
###Getting Started To use this SDK, you must have Python installed. You can use either 2.7.X or 3.3 and later.
pip install tableaudocumentapi
Download the .zip file that contains the SDK. Unzip the file and then run the following command:
pip install -e <directory containing setup.py>
Only do this if you know you want the development version, no guarantee that we won't break APIs during development
pip install git+https://github.com/tableau/document-api-python.git@development
If you go this route, but want to switch back to the non-development version, you need to run the following command before installing the stable version:
pip uninstall tableaudocumentapi
###Basics The following example shows the basic syntax for using the Document API to update a workbook:
from tableaudocumentapi import Workbook
sourceWB = Workbook('WorkbookToUpdate.twb')
sourceWB.datasources[0].connections[0].server = "MY-NEW-SERVER"
sourceWB.datasources[0].connections[0].dbname = "NEW-DATABASE"
sourceWB.datasources[0].connections[0].username = "benl"
sourceWB.save()With Data Integration in Tableau 10, a data source can have multiple connections. To access the connections simply index them like you would datasources.
from tableaudocumentapi import Workbook
sourceWB = Workbook('WorkbookToUpdate.twb')
sourceWB.datasources[0].connections[0].server = "MY-NEW-SERVER"
sourceWB.datasources[0].connections[0].dbname = "NEW-DATABASE"
sourceWB.datasources[0].connections[0].username = "benl"
sourceWB.datasources[0].connections[1].server = "MY-NEW-SERVER"
sourceWB.datasources[0].connections[1].dbname = "NEW-DATABASE"
sourceWB.datasources[0].connections[1].username = "benl"
sourceWB.save()Notes
- Import the
Workbookobject from thetableaudocumentapimodule. - To open a workbook, instantiate a
Workbookobject and pass the file name as the first argument. - The
Workbookobject exposes a list ofdatasourcesin the workbook - Each data source object has a
connectionobject that supports aserver,dbname, andusernameproperty. - Save changes to the workbook by calling the
saveorsave_asmethod.
###Examples
The downloadable package contains several example scripts that show more detailed usage of the Document API.
