JSON Beautifier & Validator Pro
Format, validate, and explore JSON with syntax highlighting, JSONPath browser, tree collapse, and schema inference.
About this tool
A full-featured JSON workbench that goes well beyond basic formatting. Beautify with 2-space, 4-space, or tab indentation. Sort keys alphabetically, strip null values, and compact short arrays onto a single line. Syntax-highlighted output uses distinct colors for strings, numbers, booleans, and nulls. The interactive tree view lets you collapse and expand nested objects and arrays. Click any key to copy its JSONPath expression. Schema inference analyzes your JSON and reports the inferred type for every field — string, number, boolean, null, array, or object — with array element type summaries.
How to use
- 1 Paste or type your JSON into the editor on the left.
- 2 Choose indentation (2 spaces, 4 spaces, or tab) and toggle sort-keys, remove-nulls, compact-arrays.
- 3 Click Format to see the beautified output with syntax highlighting.
- 4 Switch to Tree View to browse, collapse, and expand nested nodes.
- 5 Click any key in the tree to copy its JSONPath.
- 6 Open the Schema tab to see inferred types for every field.
