Instructions

Software Usage Instructions

Enter text content: Enter the text to be converted in the text input box. Any characters are supported, including Chinese, English, numbers, and symbols.
Select encoding format:
- UTF-8 (Unicode): Supports all characters, including Chinese, Japanese, emojis, etc.
- ASCII: Only supports English letters, numbers, and basic symbols (0-127)
- Latin-1: Supports the Western European character set (0-255)
Select output format:
- Space-separated: numbers are separated by spaces (e.g., 65 66 67)
- Comma-separated: numbers are separated by commas (e.g., 65, 66, 67)
- Line-separated: each number appears on its own line
- No separator: all numbers are joined together (e.g., 656667)
Select conversion mode:
- Convert by character: Displays the Unicode code value of each character
- Convert by byte: Displays the byte values of characters in the specified encoding
Start conversion: Click the "Convert" button or enter text directly to automatically convert it into decimal values.
Copy and reverse conversion: You can copy the conversion result, or use the "Reverse Conversion" feature to convert decimal values back into text.

FAQ

A: Text to decimal conversion is the process of converting text characters into their corresponding numeric codes. Each character has a unique numeric code in a computer, such as the letter 'A' corresponding to 65 and the Chinese character '你' corresponding to 20320. This is commonly used in programming, data analysis, and other fields.

A: ASCII can only represent 128 characters, mainly English letters, numbers, and basic symbols; UTF-8 is an implementation of Unicode and can represent almost all characters in the world, including Chinese, Japanese, emojis, etc. When ASCII is selected, only English characters can be entered.

A: Convert by character displays the Unicode code value of each character, with one value per character; Convert by byte displays the byte values of characters in a specific encoding, where one character may correspond to multiple byte values. For example, Chinese characters usually occupy 3 bytes in UTF-8 encoding.

A: In convert by byte mode, Chinese characters usually occupy 3 bytes in UTF-8 encoding, so 3 decimal values are displayed. If you choose convert by character, only one Unicode code value is displayed. This is normal and reflects the characteristics of different encoding methods.

A: The conversion results can be used in many areas: 1) programming debugging, viewing the numeric encoding of characters; 2) data analysis, processing text data; 3) cryptography research; 4) learning character encoding; 5) network protocol analysis, etc. Programmers often need to view the ASCII or Unicode values of characters.

A: After there are decimal values in the output box, click the "Reverse Convert" button to convert these values back to the original text. Make sure the value format is correct; they can be separated by spaces, commas, or line breaks. The system will automatically recognize the numbers and convert them into the corresponding characters.

A: The tool supports four output formats: space-separated (65 66 67), comma-separated (65, 66, 67), line-separated (one number per line), and no separator (656667). You can choose the appropriate format based on your usage needs and subsequent processing requirements.

A: The tool uses local processing and converts text of normal length very quickly. Processing extremely large text may take a few seconds, so it is recommended to process especially long text in sections. All processing is completed locally and is not uploaded to the server, ensuring data security.
