JSON Utils
Claude connectorCommunity30 free, read-only JSON and developer tools: format, validate, repair, diff, convert, and generate types or schemas. No login; nothing stor…
JSON Utils gives Claude 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. Inputs are processed in memory and are not stored or logged. No account, API key or cost.
JSON Utils is #6,676 of 11,065 Claude connectors by popularity.
