I'm looking for a desktop application that lets you check whether a json file satisfies a certain json schema. I've found some web applications that do the job, though I have to use the tool on Windows without being connected to the Internet. It would be nice if the tool has a UI that allows me to edit the json file and the schema. It would also be nice if the tool tells me exactly what's wrong with a given json file that violates the schema. However, I can live without these two features.
I'm aware to the fact that JsonBuddy can validate jsons with respect to a schema but I prefer a freeware if one exists. Unfortunately, I couldn't have found one. Is there such a tool?
