FAQ

Frequently asked questions

What does JSON Viewer do?

It helps you view and inspect JSON in a readable form and then copy or download the result where supported.

Can I paste data instead of uploading a file?

Yes. The JSON tools support direct text input, and file upload is optional for many workflows.

Why do I see a syntax error?

The input may contain invalid JSON, CSV, XML, or YAML syntax. Check quotes, commas, brackets, and indentation.
