Reference Tables

Lookup tables for hex, decimal, binary, and ASCII values.

About Reference Tables

Sometimes you need to scan a whole range of values rather than convert one at a time. This category provides lookup tables for hex, decimal, binary, and ASCII values, for exactly that case.

Frequently Asked Questions

When should I use a table instead of a converter?

When you need to see a whole range at once — like every byte value 0-255 — rather than convert a single number.

What's on the ASCII hex table?

Every standard ASCII character alongside its hex and decimal code, useful for reading raw byte dumps.
