Minecraft UUID Converter

This tool converts Minecraft player identity between UUIDs and usernames, intended for developers, admins, and data engineers who handle player data, logs, and analytics. It uses Mojang's public API for live lookups and provides an offline UUID generator to work without external access. The converter supports both directions (UUID to name, and name to UUID) and returns clean, normalized results suitable for databases and reports.\n\nHow it works conceptually: when given a UUID, the tool queries the Mojang endpoint to fetch the current username; when given a username, it fetches the most recent UUID. If the API is unavailable, it derives an offline UUID from the username using the standard OfflinePlayer namespace for consistent records. Output includes the mapped value and a timestamp.\n\nCore features and use cases: real-time mapping, hyphen normalization, lowercase hex formatting, compatibility with hyphenated or non-hyphenated UUIDs, support for name histories, and optional result caching. Typical workflows include ingesting logs with numeric IDs and mapping them to names, reconciling legacy data, or preparing onboarding data by resolving a player's UUID from a given name.\n\nValue proposition and differentiators: reliable API-backed lookups, offline fallback, explicit input validation, and structured outputs suitable for ETL pipelines. The tool supports batch readiness through internal batching and outputs use consistent formatting to ease integration with analytics platforms.
