LocalKitAbout JSON Validator
The validator checks whether a document can be parsed as standard JSON. It catches malformed separators, unquoted names and invalid syntax.
Why use JSON Validator?
Validate before importing data into an application. Syntax validity does not guarantee the data matches a particular schema.
