Custom Theme Generator
A new 100% free tool for Tableau 2025.1

Tableau 2025.1 is right around the corner and with it, Custom Themes.
The Custom Theme feature, long requested by the Tableau Community, allows you to change many formatting options in your Tableau workbook simultaneously.
The feature is great, but as a user, the experience of creating and modifying a Theme could be improved.
A Custom Theme in Tableau must be configured through a JSON file. You must check which formatting options are available, ensure that no typos are made, and constantly go back and forth in Tableau to see the results of your changes.
That’s why we created: Custom Theme Generator!
Instead of writing your JSON manually, you can edit the different formatting options, see the result live, and click Export when ready!
We added all the formatting options that Custom Theme supports. In my opinion, some important ones are still missing, but hopefully, Tableau will continue to add more options.
The best part about this tool is that it’s 100% free!
Tableau 2025.1 is not available yet, but as soon as it is, give the Custom Theme a try!
We still have this challenging goal of releasing one new product and a major update every month! That’s it for February!
March will be even more challenging as we start heavy renovation, but we have already begun working on cool stuff. 💪
Stay tuned!
