Use focused utilities for structured data, identifiers, encoding, formatting, and development checks. Validation confirms the rules implemented by a tool; it does not prove that input is trustworthy or correct for every runtime.

Most used
JSON Formatter
Parse and reformat valid JSON with two-space, four-space, tab, or minified output. The formatter reports syntax errors rather than attempting to repair malformed input.
In your browserUUID Generator
Create up to 1,000 random UUID version 4 identifiers in the browser with the native cryptography API, one canonical lowercase value per line.
In your browserTimestamp Converter
NewConvert Unix timestamps in seconds or milliseconds to ISO 8601, UTC, and local time, or parse a date string back to epoch values. Pick the input type when detection is ambiguous.
In your browserLorem Ipsum Generator
Generate a chosen number of placeholder words, sentences, or four-sentence paragraphs from a fixed six-sentence local Lorem Ipsum corpus for layout testing.

In your browserBcrypt Generator
NewGenerate salted bcrypt password hashes with a selectable cost factor, right in your browser. Useful for seeding test data and migrations rather than as a full auth system.

Edit JSON in a local text area, validate and format it with two-space indentation, or minify it. Copy or download the current document when finished.
In your browserJSON to XML
Convert JSON into well-formed XML using documented rules for arrays, null values, invalid property names, escaping, and the required root element.
In your browserJSON Viewer
Parse a JSON document and explore its arrays, objects, keys, and primitive values as an expandable browser tree with bounded visual depth and entries.
In your browserSHA-256 Generator
NewCompute a lowercase hexadecimal SHA-256 digest from any UTF-8 text using the browser's Web Crypto API. Compare digests to detect even single-character changes.
In your browserSHA-512 Generator
NewGenerate a SHA-512 hash of any text as a fixed 128-character hex digest. Runs on the browser's Web Crypto API, so your input never leaves your device.
