Cleaning up bibtex files

Sometimes bibtex files are Frankenstein's monster like documents crafted quickly from the scraps of project's past or assembled quickly from the bibliographies of review chapters using ADS or Google Scholar. A really incredible tool to clean bibtex files has been created by FlamingTempura called bibtex-tidy.

Here is the GitHub page: https://github.com/FlamingTempura/bibtex-tidy

But here is a link directly to a web browser tool that one can just paste one's bibtex file into to clean-up: https://flamingtempura.github.io/bibtex-tidy/index.html

Make sure to keep back-up copy.
