Privacy and operation
This tool runs entirely in your browser using the built-in JSON parser. Input and output are not uploaded, saved to Lynxbee, included in the URL, or shared with analytics. Usage analytics receive only the tool name, action, and success state after an analytics provider is explicitly enabled.
What validation covers
The validator checks strict JSON syntax. Property names and string values require double quotes; comments, trailing commas, functions, and JavaScript-specific values such as undefined are not valid JSON.
Handling confidential data
Local processing reduces unnecessary disclosure, but clipboard history, browser extensions, screen recording, and managed-device software can still access information. Avoid processing production secrets when the device itself is not trusted.
