Frequently asked questions
Questions about JSON Formatter
Is my JSON data sent to a server?
No. All formatting happens entirely in your browser. Your data never leaves your device.
What is the maximum file size?
The tool handles JSON up to several megabytes. For very large files, browser memory may become a constraint.
Can I format JSON with comments?
Standard JSON does not support comments. Remove comments before formatting, or use a JSON5 parser if needed.
