How to Create an Empty Column Name in Tableau


Quick tip on how to create a blank field name in Tableau. Create a calculated field to be the blank column and save it as normal – i.e. with a name!

This calculated field returns a zero length string

Renaming the calculated field with a blank causes an “empty name is not allowed” error in Tableau. Naming with a space character doesn’t work, it returns the same error.

The solution is to use a zero width space character as the name. Tableau recognises this as a character, not an empty name.

To get a blank character, go to, and search for “zero width space“.
