JSON Formatter

Pretty-print, minify and validate JSON in one place. Detect syntax errors with line and column hints, sort object keys, customize indentation and copy clean JSON for APIs, logs and configuration files.

Pretty Print Minify JSON Validation & Errors Key Sorting

Format, Minify and Validate JSON

Paste raw JSON, choose your indentation and optional key sorting, then format or minify it. The JSON Formatter highlights parse errors with approximate line and column positions so you can quickly fix issues in API responses, log files or configuration objects.

The formatter expects valid JSON (double-quoted keys and strings). For JavaScript objects with single quotes or trailing commas, adjust them to standard JSON first.

Sorting keys can make large configuration files easier to diff and compare, but it may change the order of properties relative to the original JSON.

Minify JSON by removing all unnecessary whitespace and line breaks, producing a compact one-line string ideal for embedding in code, URLs, or small config files. The minifier also validates the JSON before generating output.

JSON Formatter Inputs

JSON Formatter uses JSON input, Indentation, Sort object keys.

JSON Formatter Formula or Method

JSON Formatter is better described by a rule sequence than by one universal algebraic equation. The tool validates the supplied values, normalizes the units or formats needed by the selected mode, applies the calculator-specific lookup, date, scoring, conversion, or conditional rules, and then formats the resulting output.

Reading JSON Formatter Results

The results include Status, Root Type, Structure Summary, Formatted JSON, Minified JSON, Length Before.

Alongside JSON Formatter, use Hash Generator to generate cryptographic hashes (MD5, SHA-1, SHA-256, SHA-384, SHA-512) and HMAC in your browser. Supports text, bulk and file hashing.

For a different result from JSON Formatter, Base64 Encoder & Decoder can encode text or files into Base64, and decode Base64 back into plain text or downloadable files — all processed directly in your browser for security.
