G-code viewer
Open a .tap, .nc, .gcode or .cnc file directly in your browser. It highlights G/M-codes and axes, and lets you save the result as .txt — the old rename trick, done properly.
Why a .tap file is just text
A .tap, .nc or .cnc file is plain text. Rename it to .txt and it opens in any editor. This tool does that for you, with colors so you can spot G-words, M-words and axes (X/Y/Z) at a glance.
Is my file uploaded anywhere?
No. Everything happens in your browser. Nothing is sent to a server.
Which extensions work?
.tap, .nc, .gcode, .cnc, .ngc, .txt — and really any plain-text file.
