How it works

Enter hexadecimal byte values to generate an ASCII table showing the character representation of each byte. The tool displays hex values alongside their decimal equivalents and corresponding ASCII characters.

Printable characters (0x20-0x7E) are shown directly. Non-printable control characters (0x00-0x1F, 0x7F) are displayed with their standard names (NUL, SOH, LF, CR, etc.) or escape sequences.

Extended ASCII (0x80-0xFF) shows the character if displayable, with Unicode code point information. Results are presented in a tabular format with configurable columns for easy reference.

When You'd Actually Use This

Character Encoding Reference

Look up ASCII codes and their hex values for programming and data encoding tasks.

Binary File Analysis

Interpret hex dumps by seeing which bytes correspond to printable ASCII characters.

Protocol Debugging

Analyze network protocol data to identify ASCII commands and responses in hex streams.

Education

Learn ASCII encoding and the relationship between character codes and hex values.

String Manipulation

Find hex codes for specific characters when crafting strings for testing or exploits.

Data Validation

Verify that data expected to be ASCII doesn't contain unexpected control characters.

What to Know Before Using

ASCII range: Standard ASCII is 0-127 (0x00-0x7F). Extended ASCII (128-255, 0x80-0xFF) varies by code page.

Control characters: 0x00-0x1F and 0x7F are non-printable control codes like NUL, TAB, LF, CR used for device control.

Printable range: Printable ASCII is 0x20 (space) through 0x7E (~). This includes letters, digits, and punctuation.

Common codes: Space=0x20, '0'=0x30, 'A'=0x41, 'a'=0x61. Knowing these helps with quick mental conversion.

UTF-8 compatibility: UTF-8 is backward compatible with ASCII for 0x00-0x7F. Higher values are multi-byte UTF-8 sequences.

Common Questions

What is 'A' in hex?

'A' is 0x41 (decimal 65) in ASCII. Lowercase 'a' is 0x61 (decimal 97). The difference is 0x20 (32).

What does 0x0A mean?

0x0A is Line Feed (LF), the Unix newline character. Windows uses 0x0D 0x0A (CRLF) for line endings.

What is the hex for space?

Space character is 0x20 (decimal 32). It's the first printable ASCII character after the control codes.

How do I find hex for any character?

Use the text-to-hex converter for full strings, or note that ASCII letters are sequential: 'A'=0x41, 'B'=0x42, etc.

What are control characters?

Control characters (0x00-0x1F, 0x7F) control devices rather than display. Examples: 0x09=TAB, 0x0A=LF, 0x0D=CR, 0x1B=ESC.

What is 0x7F?

0x7F is DEL (delete), the last 7-bit ASCII code. It was used to mark deleted characters on paper tape.

Can I see extended ASCII?

Extended ASCII (0x80-0xFF) varies by code page. Modern systems use UTF-8 where these are multi-byte character starts.
