Frequently Asked Questions

What is ASCII?

ASCII (American Standard Code for Information Interchange) is a 7-bit character set with 128 codes used for basic English text and control characters.

Why are some characters blank?

Codes 0–31 and 127 are control characters (non-printable). They are listed with standard control names instead of a visible glyph.

Can I copy hex or decimal values?

Yes. Click a row or use the copy action to copy decimal, hex, or character values to your clipboard.

Does this include extended ASCII?

This table covers standard ASCII 0–127. Extended 128–255 codes depend on locale and are not included here.
