JSON is the lingua franca of web APIs. The JSON formatter beautifies minified JSON into readable, indented structure — essential when debugging API responses. It also validates syntax, catching missing commas and unmatched brackets instantly. Need to convert JSON to a spreadsheet? The JSON ⇄ CSV converter handles it in one click.
Regular expressions are a developer superpower. The regex tester provides real-time match highlighting, capture group display, and a replace mode for search-and-replace operations. New to regex? Our Regex for Beginners guide covers patterns, quantifiers, groups, and real-world examples.
The diff checker compares two text blocks and highlights every addition, deletion, and modification. It uses the LCS algorithm and offers both unified and split-view modes. Invaluable for comparing code versions, reviewing edits, and verifying config changes.
Base64 encoding converts binary data to text — used for embedding images in CSS, transmitting data in URLs, and encoding auth credentials. The hash generator produces MD5, SHA-1, SHA-256, and SHA-512 hashes for checksums and data integrity. The text-to-binary converter handles binary, hex, decimal, and octal conversions. And the URL encoder handles percent-encoding for safe URL parameters.
The SQL formatter beautifies messy queries with proper indentation and keyword uppercasing. It also offers minification for embedding SQL in code. Pair with the JSON ⇄ CSV converter for data transformation tasks.
