Data & Formatting Tools

Developers and data analysts move between formats dozens of times a day, and this hub covers the conversions that come up most. Format and validate JSON or YAML instantly, catching a missing comma or bad indent before it breaks a build. The CSV processor cleans and restructures spreadsheet exports, while the data format converter switches between JSON, YAML, CSV, and XML without a script. Base64 and URL encoding/decoding handle the everyday chores of preparing data for APIs, query strings, or email attachments. The timestamp converter turns Unix epoch values into readable dates across time zones, and the color converter moves between HEX, RGB, and HSL for design handoffs. Every tool runs client-side, so API keys, config files, and other sensitive data never leave your browser.

Format, validate, and minify your JSON data online. Free tool for developers.
