I have been testing it myself, and it works beautifully

So do most of my programs. Once I get others to start testing them, well, that's a different story ;-).

Wish to comment?

Yes, if it makes your job, and other's jobs easier/more productive, then release it. If nothing else you can include it on your resume at a later date.

Depending on your arrangement with your employer, you may also consider releasing it under an open source license.
