Developer Tools
Format JSON, encode and decode Base64, test regular expressions, and generate UUIDs. Quick utilities for everyday development tasks.
- JSON FormatterFormat, validate, beautify, and minify JSON data online. Paste raw or minified JSON and get properly indented, readable output with syntax highlighting. The tool also validates JSON structure and reports errors with line numbers. Useful for debugging APIs, formatting configuration files, and making JSON data readable. Works entirely in your browser.Developer Tools
- Base64 Encoder/DecoderEncode and decode Base64 strings online. Convert text to Base64 or decode Base64 back to readable text. Useful for encoding data for email attachments, API authentication tokens, and data transmission. Also handles URL-safe Base64 encoding. Works entirely in your browser.Developer Tools
- UUID GeneratorGenerate UUIDs (Universally Unique Identifiers) online. Create v4 random UUIDs for use as unique IDs in databases, APIs, software development, and testing. Generate one UUID at a time or batch-generate multiple UUIDs. Works entirely in your browser.Developer Tools
- Regex TesterTest regular expressions online with real-time matching. Enter a regex pattern and test string to see matches highlighted instantly. Supports common regex syntax including groups, quantifiers, and flags. Useful for debugging patterns, validating input formats, and learning regex. Works entirely in your browser.Developer Tools
Developer tools streamline common programming tasks. JSON formatting and validation helps debug APIs and configuration files, Base64 encoding converts binary data to text for email and web transmission, regex testing validates patterns against sample strings, and UUID generation creates unique identifiers for databases and applications.
All tools run in the browser with no data sent to external servers. Code snippets, configuration data, and API responses stay on your machine during processing. These are lightweight alternatives to running equivalent commands in a terminal.
