ASCII转十六进制转换器
将文本转换为ASCII十六进制代码，或进行反向转换。每个字符都会转换为其2位的十六进制值。
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').
什么是ASCII转十六进制转换器？
你文本中的每个字符都对应一个数字（基础拉丁字符用ASCII，其他一切则用Unicode码点）。十六进制是表示这些数字的紧凑形式：“A”的十进制是65，十六进制是41。这种转换在调试文本编码问题、处理二进制协议或构建转义序列时很有用。
常见使用场景
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.
