Frequently Asked Questions about Developer Tools
Does the JSON formatter highlight syntax errors?
Yes, if invalid JSON is entered, our parser points out the exact error message to assist with debugging.
Does the tool send my API responses or payloads to any server?
No. All JSON, URL, and HTML formatting executes strictly inside your local browser memory.
