Code & Data Formatters

Format, minify, and validate JSON, HTML, CSS, JavaScript, TypeScript, XML, YAML, and more—plus encoders for Base64, URL, UTF-8, hex, and classic ciphers. Free, browser-based, no install.

Start here if you are debugging

Paste a minified API response into the JSON formatter, a one-line HTML email into the HTML formatter, or a messy `.env` export into the YAML formatter. Readable structure makes missing commas, unclosed tags, and bad indentation obvious before you commit or reply to a ticket.

Naming and slug tools

Use camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and dot.case converters when renaming variables, REST fields, CSS classes, or config keys. Pair them with the slugify tool when you need URL-safe paths from human-readable titles.

Privacy for proprietary snippets

Standard formatters run in your browser after the page loads. That is useful on locked-down laptops where you cannot install CLI utilities but still need to inspect a customer payload or internal config sample.
