What is the JSON Validator & Formatter?
The JSON Validator and Formatter is a powerful, client-side developer utility built inside CSharpTools. Its primary focus is to help you easily lint, parse, and structure your messy JSON strings into readable, syntax-highlighted blocks.
Unlike external tools where your payloads are sent online, this validator works entirely inside your browser. When you interact with the validation button, the CodeMirror engine handles parsing the syntax immediately. If there is a missing bracket, invalid properties, or dangling commas, the output editor will immediately reflect the exact parsing error to help you identify the problem inside your JSON payloads quicker.
How to Use
- Paste your unformatted JSON into the left panel.
- Click the large conversion button in the middle of the screen.
