JSON Validator: private online developer utility
JSON Validator is a focused developer utility for validate schema (ajv). It is part of Sreejith Tools, a collection of fast online tools for API work, data cleanup, debugging, and web development.
When to use it
- - Clean API payloads before sharing them in tickets or docs.
- - Validate structured data copied from logs, webhooks, and config files.
- - Convert or inspect developer data without opening a heavyweight IDE.
Common input issues
- - Pasted input includes invisible whitespace or smart punctuation.
- - The source data is valid in one format but invalid in the target format.
- - A copied value includes surrounding quotes, shell escaping, or truncated content.
Example
