ASCII 轉十六進位轉換器
將文字轉換為 ASCII 十六進位碼，或進行反向轉換。每個字元都會轉換為其 2 位數的十六進位值。
如何使用本工具
- 1
Pick a direction from the dropdown: 'Text -> Hex' to encode, or 'Hex -> Text' to decode.
- 2
Type or paste your input into the text box.
- 3
Read the converted result in the output box below — it updates live as you type.
- 4
For decoding, separate each hex value with a space (for example '48 65 6C 6C 6F').
什麼是 ASCII 轉十六進位轉換器？
你文字中的每個字元都對應一個數字（基礎拉丁字元用 ASCII，其他一切則用 Unicode 碼位）。十六進位是表示這些數字的精簡形式：「A」的十進位是 65，十六進位是 41。這種轉換在偵錯文字編碼問題、處理二進位協定或建構跳脫序列時很有用。
常見使用場景
Inspecting invisible control characters (tabs, newlines, non-breaking spaces) that are breaking a parser or CSV import.
Hand-building escape sequences like \x41 for code, regex, or shell snippets.
Decoding a space-separated hex dump pasted from a log, packet capture, or protocol trace back into readable text.
Teaching or learning how characters map to numeric codes and base-16 notation.
Quickly checking the hex code of a specific symbol before hard-coding it into a config or test fixture.
Spotting smart quotes or homoglyphs by confirming whether a character is the plain ASCII version or a higher code point.
