## How to use it

1. **Paste JSON.** Paste the JSON you want to check into the editor.
2. **Validate or format.** Validate to check syntax, or format to pretty-print valid JSON.
3. **Copy the result.** Copy the formatted JSON if you need to use it elsewhere.

This tool runs entirely in the browser. Fluent BI does not receive the file or text you paste.
