JSONLint

Description

JSONLint is a web-based editor, syntax validator, and beautifier for JSON, a lightweight, language-agnostic data-interchange format. It allows users to paste, type, or load JSON from a URL to check for syntax errors, highlighting line numbers and error details for quick debugging. It also formats messy JSON into readable output and provides a “Compress” function to minify. The tool operates entirely in-browser with no signup needed and ensures privacy by not storing user input.
