How to use this tool
1
Paste or type a JSON object, array, string, number, boolean, or null into the input panel.
2
Choose Format to pretty-print the JSON, Minify to remove unnecessary whitespace, or Validate to check the syntax without changing your input.
3
Use Copy output to copy the result. Invalid JSON displays a parsing error so you can locate and correct the problem.
