This turns patterns from regular punchcards to those that work with colour changers, so if you have a punchcard meant for 2 colour knitting but that isnt what you need, this makes it so each colour is separated. It only works with 2 colours at the moment, and it assumes you swap colour every 2 rows even if none of the other colour is present. Its fine. Edit the text yourself to remove the extra lines if its needed. Stick the output text in the text to punchcard generator to get an svg for cricut or whatever.
this one only works with 0 and 1 input. 0 means hole, 1 means not hole. the svg generator can take this format just fine.
