About Code Beautify
Code Beautify is a free, browser-based suite of developer utilities for formatting, validating, minifying and converting code and data. It covers JSON, XML, HTML, CSS, JavaScript, SQL, YAML, CSV and Excel alongside hundreds of smaller converters, encoders and generators. Everything runs in the browser with no signup required, and the site is funded entirely by advertising rather than a paid plan.
Pros & Cons
Pros
- Genuinely free with no usage caps, paywalled features or account requirement
- Enormous breadth in one place, covering JSON, XML, SQL, YAML, CSV, Excel, colour, encoding and hashing tools
- JSON viewer is one of the more capable free ones, with a tree view, validation error locations and direct export to CSV, XML and TypeScript
- Nothing to install, works from any machine including locked-down work laptops
- Long-established and widely used, running since 2013 with millions of monthly visits
Key Features
JSON viewer and beautifier
Formats, minifies and validates JSON with an expandable tree view, configurable indentation from 1 to 10 spaces, big-number handling, and one-click export to XML or CSV.
Multi-language code formatters
Beautifiers and minifiers for HTML, CSS, JavaScript, SQL, XML, Java, C#, PHP, Lua, ActionScript and MXML, each with its own dedicated editor page.
Validators
Syntax checking for JSON, XML, CSS, JavaScript, YAML and TOML that reports the error location so malformed input can be traced and fixed.
Format converters
Two-way conversion between JSON, XML, YAML, CSV, TSV, SQL, TOML and Excel, plus JSON to TypeScript interfaces, PHP arrays, JSONL and JSX.
Encoding and cryptography tools
Base32, Base58 and Base64 encode/decode, URL and HTML encoding, UTF-8 and hex conversion, JWT decoding, MD5/SHA-256/SHA-512 hashing, HMAC generation and gzip compression.
Image and Base64 utilities
Image to Base64 and back, PNG/JPG/BMP/GIF conversion, SVG viewing and formatting, GIF splitting, pixelation and screenshot beautifying.

Best For
Reading an unformatted API response
Paste a minified JSON payload from a log or API call and get an indented, collapsible tree view to find the field you need.
Debugging a syntax error
Run malformed JSON, XML, YAML or CSS through the matching validator to get the line and column of the break instead of a vague parser message.
One-off data format conversion
Turn a JSON export into CSV for a spreadsheet, an Excel sheet into JSON for a fixture, or a SQL result into YAML, without writing a throwaway script.
Quick encoding and hashing checks
Decode a JWT to inspect its claims, Base64 an image for an inline data URI, or generate a SHA-256 hash to verify a value while debugging.
