JSON Stringify and Unescape は何をしますか？
JSON Stringify and Unescape はブラウザ上でコンテンツをエンコードまたはデコードするツールで、結果と制限を明確に示します。 検証済みの機能： JSON stringify, JSON unescape, JavaScript literal output, Unicode-safe processing.
Transform only at a syntax boundary
Use stringify when embedding a text value in JSON or source code, and unescape when you need the represented text. Do not repeatedly escape intermediate values.
使い方
- Paste plain text or a complete JSON string literal.
- Select stringify, unescape, or JavaScript literal output.
- Run the transformation and copy the exact result.
実際の入出力例
Represent a line break inside JSON
入力
Hello
world出力
"Hello\nworld"Stringify adds quotes and escapes the line break so the result is one valid JSON string value.
一般的なエラーと対処
| 症状 | 原因 | 対処 |
|---|---|---|
| Unescape says the value is not a string. | The input is not a complete quoted JSON string literal. | Include the opening and closing double quotes and valid JSON escapes. |
| The result is escaped twice. | Already escaped text was stringified again. | Unescape once, inspect the plain value, then stringify only for the final destination. |
Important behavior of JSON String
このツール固有の制限： Escaping changes syntax representation; it does not encrypt, sanitize, or make untrusted content safe for every context.
標準と実装の参考資料
- ECMAScript JSON.stringify (opens in a new tab)Defines JSON serialization behavior.
- RFC 8259 — JSON (opens in a new tab)Defines JSON string grammar and escapes.
JSON String — FAQ
Does the JSON String upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the JSON String accept?
It accepts plain text or one valid JSON string literal. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the JSON String produce?
It produces escaped JSON text, unescaped text, or a JavaScript string literal. Copy and download controls appear when the output format supports them.
What limitation should I know?
Escaping changes syntax representation; it does not encrypt, sanitize, or make untrusted content safe for every context.
