About

WeJSON is an online JSON and JSON5 processing tool with a Monaco Editor-based interface. It provides a dual-pane editing interface where the left pane accepts JSON or JSON5 input and the right pane shows a formatted, read-only preview. You can format (pretty-print), minify, or sort keys in ascending or descending order. Syntax errors are highlighted inline within the editor. Files can be loaded by dragging and dropping a .json file onto the editor. The output can be copied as formatted or minified JSON, downloaded as a .json file, or exported to YAML or XML (with a configurable root element name). The JSONPath query panel lets you run queries using the full jsonpath-plus syntax, with results displayed in real time. The JSON Schema validation panel supports Draft-07 schemas entered manually or auto-inferred from the current JSON, showing each validation error with its path and reason. A built-in history stores up to 10 past entries, each of which can be restored with a click or deleted individually. The app is available in 4 languages.
