About JSONLintPlus

JSONLintPlus was created by developer, for developers, with a simple mission: to provide the most reliable, secure, and user-friendly JSON validation tool available online.

Our Story

JSONLintPlus emerged from a common frustration among developers: existing JSON validators either compromised on privacy by uploading data to remote servers, lacked essential features, or were cluttered with unnecessary complexity. We believed there should be a better solution—one that prioritized both functionality and user privacy.

Our Commitment to Privacy

What sets JSONLintPlus apart is our unwavering commitment to privacy. All JSON processing happens entirely within your browser using client-side JavaScript. Your data never leaves your device, never gets transmitted to our servers, and is never stored or analyzed. This approach eliminates security risks associated with cloud-based validators while delivering faster performance without network latency.

Technical Excellence

Our validation engine is built with precision and performance in mind. It provides detailed error reporting with exact line and column numbers, supports large files, and includes advanced features like syntax highlighting, tree view visualization, and JSON schema validation. The tool is continuously updated to support the latest JSON standards and browser capabilities.

Open Source Philosophy

We believe in the power of open source software. JSONLintPlus is built with open-source technologies and follows web standards for maximum compatibility. Our code is regularly audited for security and performance, ensuring a reliable tool that developers can trust.

Looking Forward

JSONLintPlus is continuously evolving based on user feedback and emerging web technologies. We're committed to maintaining the tool as a free resource for the developer community, with no premium tiers or usage restrictions. Your feedback helps us prioritize new features and improvements that matter most to developers worldwide.
