Frequently Asked Questions
How do I format messy JSON?
Paste your JSON into our formatter and click Format. It instantly adds proper indentation and line breaks. If your JSON has errors, the tool highlights exactly where they are.
What's the difference between Format and Minify?
Format adds spaces and line breaks for readability. Minify removes all whitespace to create the smallest possible file — useful for API requests and production deployments.
Can I validate JSON without formatting it?
Yes — just paste your JSON and the tool automatically validates it. Errors appear in red with the exact line and position. No need to click anything.
Does this work with large JSON files?
Yes, our formatter handles JSON up to several megabytes. For extremely large files (50MB+), your browser may slow down, but typical API responses format instantly.
