JSON Formatter

Beautify compact or irregular JSON with consistent indentation while preserving every parsed value. Your input is processed locally in the browser and is not uploaded to YourConvertor.

How to use JSON Formatter

  1. Paste valid source data into JSON Formatter.
  2. Choose formatting options such as Indent.
  3. Run JSON Formatter to create the normalized representation.
  4. Compare the result with the source, then copy it for its intended use.

Common uses

  • Make minified API responses readable
  • Normalize JSON before code review
  • Inspect nested configuration files

Example input

{"hello":"世界"}

Example result

{
  "name": "YourConvertor",
  "private": true
}

Common mistakes

  • Trailing commas
  • Unquoted property names
  • Missing closing braces

Tips for reliable results

  • Validate the source first when formatting reports an error; indentation cannot repair malformed data.
  • Compare parsed values rather than whitespace when reviewing the formatted result.
  • Preserve the original source until the normalized output has been accepted by the target system.

Frequently asked questions

Does formatting change JSON values?

No. Formatting changes whitespace and indentation, not the underlying values.

Can it format nested arrays?

Yes. Objects and arrays at every depth are indented consistently.

Why does JSON Formatter reject data instead of repairing it?

Formatting preserves meaning and therefore requires valid source syntax. Automatic repair could silently change values or structure.

How should I verify the formatted result?

Parse or validate the result, then compare its data values with the original rather than comparing whitespace.

Does JSON Formatter upload my data?

No. Supported JSON Formatter processing runs locally in your browser.

What is the Web Free input limit?

The maximum input size is 5 MB per operation. For a larger input, reduce it to a representative sample or process it in smaller sections.

意味を変えない JSON 整形

文字列、数値、配列、オブジェクト構造を保ったまま JSON を読みやすくします。

注意すべき失敗

末尾カンマと単一引用符は JavaScript の慣習であり、正しい JSON ではありません。

安全上の境界

認証情報を削除し、整形後に解析した構造を比較してください。

解像度、コントラスト、回転、言語選択で認識精度を上げます。

注意すべき失敗

低解像度、傾き、誤った言語モデルで文字を誤認します。

安全上の境界

画像はローカルに保ち、氏名、数値、句読点を確認してください。
