1. Validate & View

Paste your JSON into the left editor. The tool validates in real-time. If there is an error, the specific position and reason will appear below the editor.

2. Side-by-Side Diff

Switch to Compare Mode to see two JSON files side-by-side. Our engine recursively traverses nested structures to find value and structural gaps.

3. Format, Sort & Minify

Use the Beautify button to add indentation, Sort Keys to alphabetically reorder object keys, or Minify to remove whitespace for efficient data storage/transfer.
