JSON formatter
Format, validate, and minify JSON directly in your browser. Find syntax errors, switch between readable and compact output, and copy the result without uploading your data.
How to use JSON formatter
- Paste JSON into the input, or load the example.
- Choose Format for indented output or Minify for a compact string.
- Review the result and copy it when you are ready.
A few small questions.
Does my JSON leave my device?
This tool processes the text in your browser. It does not send the input or output to a TinyDing server.
Does this fix invalid JSON automatically?
No. Invalid input produces an error so you can correct the source deliberately.
Can I format passwords or API keys?
Processing stays in this page, but you should still use sample values when sharing results. Copied text enters your system clipboard.
