When making CUSTOM number format,
In excel when you use this :
Your number format becomes optional (if larger than thousand>> k, larger than million>> m , smaller than thousand >> normal format
In tableau , when K is chosen millions also shown as K (for ex. 1,5 million becomes 1500 K) I do not want that.
Is there a CUSTOM NUMBER FORMAT like it is in EXCEL above?
Tableau does have custom number formats, but I don't believe you can replicate that formatting logic using Tableau formatting. Specifically, I don't think that Tableau allows comparison operators like [>999999] in your Excel syntax for example.
A workaround might be to build the comparison logic into a calculated field that outputs a string.
