Developer & data tools

JSON, HTML, XML, CSS, JavaScript, Base64, URL encoding, JWT, UUID, hashing, regex, and structured conversions.

Format code, encode data, test regex, convert JSON or CSV, decode JWTs, and generate UUIDs or hashes — all without sending your snippets to a backend.

Pretty-print messy JSON, minify to shrink size, validate syntax, and browse nested objects in a tree view — ideal for REST APIs and config files. Everything runs in your browser.

Indent HTML for readability, or preview rendered output inside a sandboxed iframe so scripts from your snippet cannot affect this site.

Add indentation to XML, surface parser errors, and read configs, RSS feeds, enterprise payloads, or SVG fragments more easily.

Beautify CSS for review and debugging, or minify it to strip whitespace and trim download size (formatter library loads only on this tool page).

Turn minified bundles into indented, readable code, or compress snippets by removing excess whitespace — helpful when inspecting production JS.

Encode plain text to Base64, or decode Base64 back to text with correct UTF-8 handling for emoji, accents, and non-Latin scripts.
