Why Use Formatador JSON?
Most online JSON formatters paste your data into a remote server for processing — a problem if your JSON contains API keys, user data, or proprietary configuration. Zeraku's JSON Formatter works entirely in your browser: nothing is ever sent anywhere. It also goes beyond simple formatting with a collapsible tree view, built-in validation, type inspection, and one-click conversion to CSV or YAML — features usually locked behind paid tools.
Why Use Zeraku Instead of Other JSON Tools?
Most online JSON formatters send your data to a server. Zeraku runs entirely in your browser — critical when your JSON contains API keys, passwords, or proprietary data.

Beginner's Guide
JSON is a text format used by apps and websites to store and exchange data. When JSON is minified (squeezed into one line), it is nearly impossible to read. This tool takes messy or compact JSON and reformats it with proper indentation so you can read it easily. Just paste your JSON text into the editor and click Format. You can also use the tree view to explore nested data visually, and validate whether the JSON is correctly structured.
Technical Details
The editor is powered by Monaco Editor (the engine that drives VS Code) loaded via CDN, providing syntax highlighting, bracket matching, and real-time error underlining. JSON parsing uses the native browser JSON.parse() with a custom error-recovery layer that pinpoints the exact line and column of syntax errors with a human-readable message. Tree view rendering uses a virtual-DOM diffing strategy so even JSON documents with tens of thousands of nodes render smoothly. JSON-to-CSV conversion flattens nested objects using dot-notation keys. JSON Schema validation uses the Ajv library compiled to a single WASM bundle. All operations are synchronous on the main thread since typical JSON documents are small enough not to block the UI.
