Is it possible to do conditional highlighting of booleans in Apple Numbers?

I want to highlight TRUE values one way, and FALSE values another, but booleans don't seem to be supported - only numbers, text, dates, durations and blank:


I tried using "Numbers" => "equal to" but it didn't seem to accept my attempt at doing "equal to" FALSE.

I'm currently using Numbers 3.5.3.

One possible, hacky, workaround would be to change them from booleans to strings.

It looks like Apple has implemented this functionality natively now (at least on Numbers 11.2) so that no language-dependent workaround is needed.

When setting up a Highlighting Rule, choose Cell icon Cell as type, and there you will find the "Is true""Is false" rules


A boolean in Numbers seems to be represented internally as a String already. Setting "text is TRUE" and "text is FALSE" worked for me.


The OP does not specify how TRUE or FALSE are represented in the cell, but as was stated in another answer, using text is rule will work. This also works for checkboxes, they resolve to TRUE and FALSE as well.

  • Text is TRUE add formatting
  • Text is FALSE add other formatting

This works for the result of a formula returning the text TRUE or FALSE. If one is using numbers for Booleans, i.e.: 0 or not 0 then use a number rule.

  • Number is equal to 0 [zero representing FALSE] add formatting
  • Number is not equal to 0 [in the case of any number is TRUE] other formatting

See screenshots for examples.

IMHO, these answers are really bad advices if you happen to collaborate with other who have theirs macs not in the same language (so does Numbers). What I mean is if you edit the document in English and then hand it over to someone else who happens to have - let's say - Italian as default language, it will fail.

The only way I made it work was to introduce additional, hidden column that will explicitly convert value from the boolean column into 0/1 and filter by that hidden column.
