A wise person once said "If it's free, the price is right." There's lots of free formatting to be had at freeformatter.com, to the tune of more than formatting, actually. Here are the main categories of free conversion, help, code, etc. only a click away:
Formatters
Validators
Encoders & Decoders
Code Minifiers / Beautifiers
Converters
Cryptography and Security
String Escaper and Utilities
Web Resources - including a Lorem Ipsum generator?!
I'm only just getting familiar with many of these tools and many I don't even know what are good for (bad English but you understand). I have a word of caution for you regarding the Cryptography section, though: use at your own risk.
I don't mean to suggest that there are flaws with the tools. As far as I know, the tools work just fine. What I don't trust is endpoint security (me and a BUNCH of people smarter than me). Your hashes or SHA-whatevers are probably handled flawlessly by this free website, but if they're being created via a compromised laptop or (gag) phone, then browser https won't save the day.
So for best results, use these free tools from a box and network you trust, rather than over free wifi at a coffee shop or over the library system at a high school. And not with a laptop that hasn't been updated in a year.
Just sayin'.
