Add Comments to Calculations

Hey Tableau Community! Did you know you can add comments directly into your Tableau calculations? This simple trick can make your work more understandable, easier to revisit later, and more collaborative for anyone else working with your dashboards. It's a great way of documenting calculations as you go!

How to Add Comments in Tableau 💬

Single-line comments

Use // to create a comment

Multi-line comments

If your explanation stretches across several lines, start with /* and end with */

Why Comments Matter

Documenting your work isn’t just good practice - it’s essential:

• Helps you understand your logic when revisiting a workbook after a break.

• Makes it easier for others to follow your thought process and maintain your dashboards.

• Keeps calculations clean, organized, and transparent.

Best Practice Tip 💡

Whenever you create a new calculated field, add a brief comment explaining what it does and why you built it. It only takes a moment, but it can save hours down the line!
