Data & Encoding tools
JSON, Base64, CSV, and URL encoding - the format conversions every project needs eventually.
JSON to TypeScript Interface Generator
Paste a JSON sample - a TypeScript interface, nested objects broken into named interfaces.
Base64 Encoder/Decoder
Encode or decode Base64 with correct UTF-8 handling - emoji survive the roundtrip.
JSON to CSV Converter
Paste a JSON array of objects - a proper CSV, columns are the union of keys across every row.
URL Encoder/Decoder
Encode or decode a URL component or a full URL - two distinct modes for two different jobs.
Visual Regex Builder
Compose a regex from building blocks - pattern out, plain-English explanation.
