Description:

This function is case sensitive, but the values do not need to be alphabetized, and the duplicates do not need to be next to each other. It will leave the list in the order it received it, minus any duplicates.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

That's possible, but it would require some extra work. Also, certain plurals would be more problematic, such as jelly/jellies.

After giving it more thought, I'm not sure how well it would work in practice. You'd have to do multiple passes to remove plurals that were encountered before their singulars, among other issues.

Unfortunately, this will take more time than I can spend pro bono. Good luck!

Could this be adjusted to remove duplicate strings of text as opposed to just a single word?

Scott, I think it does that already. Did you test it? The parameter the function requires is a string; and it looks for identical strings.
