Frequently Asked Questions
How do I view JSON in a readable format?
Paste your JSON into the input box and click View JSON. The viewer formats and indents the data so nested objects and arrays are easy to read.
Can I inspect large nested JSON and API responses?
Yes. The viewer is built for deeply nested JSON, large arrays and real API responses, presenting them in a clean, scrollable structure.
Does the JSON viewer validate my JSON?
Yes. If the JSON is invalid the viewer reports the parser error so you can fix syntax issues before using the data.
Is the JSON viewer private and safe to use?
Yes. All JSON parsing and viewing happens locally in your browser. Your data is never uploaded to a server or stored.
