Frequently Asked Questions
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data format widely used for storing and exchanging structured data between web clients and servers.
Is my JSON data uploaded to a server?
No. The conversion and validation process happens entirely inside your web browser. Your private API payloads or JSON data are never sent to external servers.
