JSON Formatter

Expand compressed JSON into a readable structure for API responses, logs, and examples. Formatting runs locally in the browser.

  1. Open the tool
  2. Add the content you want to process
  3. Check the result before you copy or download it

API debugging

Turn minified responses into readable structures before you inspect fields.

Data review

Format copied logs or payloads so nested arrays and objects become easy to scan.

Docs cleanup

Present example JSON in a cleaner format before sharing it in docs or tickets.

Confusing formatter with validator

A formatter improves readability. A validator tells you whether the JSON is actually valid.

Ignoring escaped JSON strings

Logs often contain stringified JSON. Check whether you are formatting raw JSON or a wrapped string first.

FAQ

Is a JSON formatter the same as a JSON validator?

Not exactly. A formatter focuses on readability, while a validator checks whether the structure is valid JSON.

Can I use it for API responses?

Yes. It is especially useful for minified responses and log payloads.

Does it upload my JSON anywhere?

No. Formatting, minifying, and validation stay in the browser.

Can it minify JSON?

Yes. Minify removes whitespace. It does not encrypt the data or replace validation.

What if validation fails?

Check trailing commas, comments, or a JSON string wrapped in quotes. Escaped log text may need to be unwrapped first.
