JSON Checker

JSON Checker is a console-based tool implemented as a Pushdown Automaton that very quickly determines if a JSON text is syntactically correct. It could be used to filter inputs to a system, or to verify that the outputs of a system are syntactically correct.

JSON Checker is a straight C# port of JSON_checker written in C.

Download

Download JSON Checker v1.0 (build 9330) . It includes C# source code as well as binaries compiled in debug and release configurations.

Usage

JSON Checker reads the JSON text source from the standard input and emits a message on the standard error as soon as it encounters a syntax error. JSON Checker does not attempt to recover errors so it halts further processing once a syntax error has been detected. To check a file, use JSON Checker on the Windows Command Prompt as follows (replacing FILE with the actual file path):

$ jsonchk < FILE

To check several files in a single run, consider using FOR like this:

$ for %i in (*.json) do jsonchk < %i

Requirements

JSON Checker requires requires Microsoft .NET Framework 2.0 to run and supports the same set of operating systems as the runtime.
