Convert text to decimal ASCII codes and back instantly
When converting text to decimal, each character is converted to its ASCII (American Standard Code for Information Exchange) value—a number between 0 and 127 for standard ASCII. For example, the capital letter "A" has ASCII value 65, lowercase "a" is 97, and the space character is 32. Decimal representation shows these values in standard base-10 format, making character codes human-readable.
ASCII is a fundamental character encoding standard in computing. Numbers 0-31 are control characters, 32-126 represent printable characters, and 127 is the delete character. Extended ASCII (128-255) handles additional characters for different languages. Understanding ASCII values helps programmers debug text processing issues, validate input, and work with character-level operations.
Decimal conversion is useful in programming when you need to check character codes, validate input types, or transform text data. It's commonly used in security contexts to understand encoding schemes, in educational settings to teach character representation, and in data processing where text must be analyzed at the character level.

Standard ASCII uses values 0-127. Extended ASCII goes to 255. Most printable characters fall between 32 (space) and 126 (tilde ~).
This tool primarily handles ASCII. For Unicode characters with values above 127, results depend on character encoding. Standard ASCII text works perfectly.
Enter decimal values separated by spaces, like "65 66 67", which converts to "ABC". The converter automatically handles spacing.
