From Config Files to Codebases: A Field Guide to the Formats Developers Format Every Day
Most developers don't think of themselves as working with "data
formats" -- but between a Dockerfile, an Nginx config, a
.env file, some YAML, and whatever language the actual
application is written in, format-wrangling is a constant, quiet
part of the job. Each one has its own quirks: Dockerfiles care about
instruction case and layer order, Nginx configs live and die by
matching braces, and .env files are deceptively easy to
get subtly wrong (quoting, especially).
We built FormatterHub to cover this whole surface -- not just JSON/XML/JS, but the config files and languages that surround them -- because a project's data problems rarely live in just one format. Being able to paste any of it into one consistent, honest tool (one that tells you plainly when it's doing "best effort" formatting versus a fully-verified parse) saves the mental overhead of remembering which of a dozen single-purpose sites handles which format.
