JSON Utils
JSON Utils gives your AI exact, deterministic tools for everyday JSON and developer work, so results are computed rather than guessed.
Validate JSON and get the line and column of any syntax error; repair broken JSON from LLM output; format, minify, sort, flatten, diff and query JSON with JSONPath; convert between JSON, CSV, YAML, XML and TOON; generate TypeScript, Zod, Pydantic, Go and Rust types from a sample; generate and validate JSON Schema; fix schemas for OpenAI strict structured outputs; and use helpers for Base64, URL encoding, JWT decoding, hashes and HMAC, UUID/ULID, timestamps, SQL formatting, cron explanations and LLM token counts. Every tool is read-only and stateless.

JSON Utils provides stateless developer tools: format, validate, repair, diff, query and convert JSON (CSV, YAML, XML, TOON, TypeScript/Zod/Pydantic/Go/Rust types), generate and validate JSON Schema, plus Base64, URL, JWT, hash, UUID, timestamp, SQL, cron and token-count helpers. Pass the data directly as text arguments. Nothing is stored or logged, and inputs are limited to 500,000 characters per argument. Tool failures return isError results with a plain-language explanation, including line and column for JSON syntax errors.
