Escape JSON
「Escape JSON」はコード、データと QRに使えるブラウザツールです。入力内容と結果は通常この端末内で処理され、登録は必要ありません。
使い方
使い方
- Choose Escape JSON or Unescape JSON, then select JSON value or JSON string literal.
- Paste valid input and submit to validate the exact syntax and escape sequences.
- Review the result, then copy it or download a JSON file.
Values and literals are different inputs
JSON value mode accepts an object, array, string, number, boolean, or null and validates the complete document. JSON string literal mode requires one JSON quoted string, such as "hello\nworld"; it rejects objects and unquoted text so the boundary stays explicit.
Visible JSON error boundaries
Malformed JSON, trailing commas, unescaped control characters, invalid escape sequences, and extra content are rejected with the browser parser message. Processing, copying, and download preparation happen locally without a backend.
よくある質問
あわせて知りたいこと
What is a JSON string literal?
It is one quoted JSON string including its surrounding double quotes, for example "hello\nworld". A plain sentence without quotes is not a JSON string literal.
Can value mode handle arrays and numbers?
Yes. It accepts every JSON root type, including objects, arrays, strings, numbers, booleans, and null.
Does this upload my JSON?
No. Parsing and conversion run in your browser.
