How it works
Updated July 2026Parsing & Validation
The Number Base Converter tokenizes and validates input against the relevant specification (RFC, W3C, or language standard). Syntax errors include line/column hints when the format supports positional parsing.
Transform Pipeline
Input passes through a deterministic transform pipeline: normalize → validate → format/encode → output. The same input always produces identical output with no server round-trip.
Encoding & Escaping
Special characters, Unicode code points, and escape sequences are handled per the target format's rules. Output preserves semantic meaning while conforming to structural requirements.
