The JSON Formatter & Validator inspects, beautifies, validates, and minifies JSON payloads. It highlights syntactic discrepancies, pinpoints line and column errors, and outputs clean indented JSON for APIs and configuration files.
📋How to Use This Tool
- Input Data: Paste your raw, minified, or unformatted JSON text into the source editor.
- Adjust Options & Presets: Select your preferred indentation depth (2 spaces, 4 spaces, or 0 spaces for minification).
- Execute Calculation: Click Format & Validate (or Minify) to parse the payload and inspect validation results.
