JSON Format Online: How to Format JSON and Fix Errors in Seconds
Short answer: Use the free JSON Formatter on Bsks. Paste your JSON, click Format JSON, and the tool beautifies it into clean, indented text — for example, {"name":"Bsks","tools":150} becomes a tidy multi-line object. It also validates your JSON and reports errors.
How to format JSON online
- Open the JSON Formatter on Bsks.
- Paste your JSON into the “Input JSON” box, or click Load Sample to try an example.
- Click Format JSON. The formatted result appears in the “Formatted Output” box.
- Use Copy to copy the result, or Minify to shrink it back to one line.
The tool validates as it formats: valid JSON gets a “Valid JSON” message, while broken JSON produces an error message so you can find the problem.
Tips for clean JSON
- Use 2 spaces of indentation for everyday reading — the tool's default — and switch to 4 spaces for deeply nested data.
- Fix missing commas and quotes first; the validator flags invalid JSON before formatting.
- Use Minify when you need compact JSON for an API request or a config file.
- Use Clear to empty both boxes before pasting a new snippet.
