Binary / Hex / Octal / Decimal Converter

Provide an interactive "ASCII Text Equivalence Table Viewer" grid element.

Note on errors: the most common slip-up here is a missing comma, an unclosed bracket, or a stray character carried over from a copy-paste. If that happens, double-check your input rather than the tool — the calculation itself runs the same way every time.

Your data stays private. Everything you type runs locally in your own browser tab. Nothing is uploaded, logged, or stored on a server — close the tab and it's gone.

This tool processes everything client-side, inside your browser window, using native browser string and encoding APIs (no external conversion service is ever contacted). Bitwise shifting structures tracking input changes instantly across grids Nothing is sent to a server, so there's no upload delay and no privacy trade-off.
