# 全角英数字と半角カナをまとめて正規化（日本語テキスト）

**Use case:** 

日本語のテキストの表記ゆれをまとめて直します。全角の英数字（ＡＢＣ１２３）は半角に、半角カナ（ｶﾀｶﾅ）は全角に、濁点の分かれた文字は1字に、ダッシュと長音は1種類にそろえます。URL・メールアドレス・コードブロックは変えません。テキストを貼るか、スクレイパーなどの出力のデータセットを選んで実行します。

## FAQ

### 全角の記号も半角になりますか？

既定（alphanumeric）では、全角の英字と数字だけを半角にし、「（）」「：」などの全角の記号は日本語の文の中で自然なのでそのまま残します。記号も半角にしたいときは fullwidthAscii を all にします。

### URL やメールアドレスは変わりますか？

Japanese Text Normalizer は URL・メールアドレス・コードブロックを変えません。リンクやコードはそのまま使えます。

### 料金はいくらですか？

Japanese Text Normalizer は入力1,000字ごとに $0.0001（100万字で $0.10）です。1文書は最低100字として数えます。ほかに Apify の Actor の開始のイベントがかかります。

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/quietworkslab/japanese-text-normalizer.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
