Format negative numbers as red

As a hardcore excel user, I feel like an idiot here not being able to do simple things I’m used to.

How can I format negative numbers to show as red in a table?


You use the “Conditional Formatting” feature which is the icon that looks like “Aa” in the table config settings:


Like this…

/edit- you can choose which columns to change colour, or the entire row if you want. :slight_smile:

Thanks… this is much simpler. Here is what I did an not getting results

I want anything that is < 0 to be red letters (not background). I realize I picked above zero… that’s not working either.

It looks like the problem is that it doesn’t know what number in the table you want to test. You just say “thisTable >0” instead of something like “thisTable.Month 1 < 0”.

/edit - this post might also be interesting. :wink: Listing all columns that are not blank

I’m trying to keep it general as the user may add multiple columns which will also need to be conditional.

Any thoughts on why thisTable >0 isn’t working?

When I enter the >0, it goes from saying “-> 10 of 10 rows” to “-> 0 of 10 rows” like something isn’t right.


You have to check a specific column, not the entire table. Either that or you could create a hidden boolean column and set up logic to make it true if any of a number of columns are negative - then you can apply formatting based on the hidden column.

That’s a clever way to do it. Not sure it would work as I can’t imagine it turning individual cells “conditional”. Please let me know if I’m not clear on this yet.

Your original solution seems like something that should work.

If you check my example above you can see I’ve added a second table with a hidden column called “Negative?” that is used to drive the colour change. Simply add whichever columns you want checked to the formula.
