About this Tool
Instantly generate production-grade Zod validation schemas (z.object, z.array, z.string, z.number) from any raw JSON API response.
Standard Technical Protocol Implementation
RFC 8259 (JSON), RFC 4648 (Base64), RFC 7519 (JWT)Text is parsed according to official RFC syntax standards. Validation routines detect syntax errors with line and column accuracy, and token decoding runs strictly client-side.
Worked Example: Data Transformation Example
Unformatted 1-line JSON payload with minified nested objects
Properly indented 2-space formatted JSON with syntax validation pass
Trailing commas, unquoted keys, and mismatched brackets are flagged with exact line indicators.
Frequently Asked Questions
Why does Base64 encoding increase data size by 33%?
Base64 takes three 8-bit bytes (24 bits total) and splits them into four 6-bit chunks. Each 6-bit chunk maps to an ASCII character, increasing total data size by exactly 4/3 (33.3%).
Is it safe to paste API keys, JSON tokens, or secrets here?
Yes. All parsing, formatting, and decoding happens inside your browser. No strings, tokens, or payloads are ever sent to an external server.
What is the difference between standard Base64 and URL-Safe Base64?
Standard Base64 uses + and / characters, which have special meanings in URL parameters. URL-Safe Base64 replaces + with - and / with _ to prevent URL corruption.
