Category FAQ
When should I use an online formatter?
Use an online formatter when you need fast cleanup for one-off snippets, payloads, or config files and do not want to switch into a local editor or CLI.
Do formatter tools change my data?
In most cases they only adjust whitespace, indentation, and layout. They are meant to improve readability rather than change the underlying meaning.
