📖 Description
1. Why Do You Need an ASCII Conversion Tool?
ASCII (American Standard Code for Information Interchange) is the cornerstone of computer communication. When dealing with low-level data, manually looking up tables is both time-consuming and error-prone:
- Protocol Debugging: When analyzing network packets or serial communication (RS232/485) data, it's necessary to convert received hexadecimal streams (e.g.,
48 65 6C 6C 6F) back into human-readable text (Hello).
- Programming Learning: Helps beginners intuitively understand how characters are represented at the computer's low level through $0$s and $1$s or hexadecimal numbers.
- Data Masking & Simple Encryption: Converts sensitive strings into numeric sequences, increasing the difficulty for non-professionals to read them directly.
- Special Character Handling: Finds the ASCII codes for invisible characters (e.g., Line Feed
LF, Carriage Return CR) to solve code formatting issues.
2. Core Feature Analysis
This site's tool provides a comprehensive radix conversion solution, meeting all needs from development to debugging:
A. Text to ASCII
- Multi-Radix Output: Supports converting text into Decimal, Hexadecimal, or Binary sequences with one click.
- Custom Separators: Supports using spaces, commas, slashes, or
\x prefixes (e.g., \x41) as separators between values, adapting to the syntax of different programming languages.
B. ASCII to Text
- Intelligent Parsing: Automatically recognizes the format of the input sequence. Whether you paste a sequence of 01s or hexadecimal codes, the system can accurately restore the original characters.
- Real-time Preview: Dynamically displays the decoding result as you input, allowing for quick error checking in data streams.
C. Complete ASCII Code Table Reference
- Built-in Lookup Table: Includes the complete $0-127$ ASCII standard reference table, containing control characters, escape characters, and their corresponding descriptions for convenient on-demand retrieval.
D. Privacy & Security (Local Computation)
- Localized Conversion: All logical operations are performed entirely in the browser frontend. Your data is never sent to the server, ensuring absolute privacy when handling keys, passwords, or internal protocols.

4. Brief Operation Process
- Select Mode: Determine whether you want "Text to ASCII" or "ASCII to Text".
- Paste Content: Paste your string or numeric sequence into the input box.
- Configure Format: Select the target radix (Decimal, Hex, or Binary) and the separator style.
- Execute with One Click: Click the "Convert" button, and the result appears immediately.
- Copy with One Click: Click "Copy Result" to directly apply it to your code, serial port assistant, or documentation.
