How to format JSON
Paste a JSON object or array into the input area and select Format JSON. The tool checks syntax and displays an indented result. Select Minify when you need a compact JSON string for an API request or configuration file.
Privacy and limitations
The formatting code runs in your browser. TxConv does not receive the JSON you enter. JSON must use double quotes around property names and string values; JavaScript object literals with comments or trailing commas are not valid JSON.
Common uses
Use this tool to inspect API responses, prepare fixtures, validate configuration files, or make JSON easier to review in a pull request.
