I was just given a job which required me to extract data from two separate Excel files, perform some calculations, and save back to a new file. I am not too familiar with Excel and I haven't used this module before, but thanks to the clear documentation I was able to complete the job quickly and accurately. Excellent!
I really like the concept of the ::Tiny modules and use this one all the time. It is ideal for small and/or new projects where the temptation is often to just stick the configuration in a hash at the top of your program. Using this module makes keeping it separate from my code trivial, and with minimum overhead.
