No server upload is required for formatting/validation. Clearing the page removes the text from memory.
Validators report problems; formatters beautify valid structure. Severely broken input may need manual fixes first.
Formatters and converters aim to preserve meaning. Always review diffs for mission-critical code before committing.
Paste smaller chunks if the tab slows down. Minifiers and deep validators scale with input size on the CPU you have.
Many tools support Ctrl/⌘+Enter to run and standard copy shortcuts. Check the tool toolbar for Sample / Clear / Download.
When options exist (spaces vs tabs, indent width), set them before copying output into your repo to match project style.
After the page loads, formatting continues offline. CDN libraries need an initial network load.
