There was a time, between stone age and modern times, when many people were formatting their code by hand. They would judge code by the beauty of it's looks. I was always of the opinion that code formatting was a machine task, and so I wrote this script for code that could not be formatted with indent, the only code formatter back then, for the c language. Now there are probably plugins for your code editor for most languages, but you might find it useful to use this website if you just have a single file to format or a new language, or do not use a fancy editor. Anyway, many people still use this service. Please let me know what for. Guessing from the feedback and the questions I get I think most use it to make sense of compact CSS. Thanks for using this service, please keep sending me feedback on how to improve it.
