How do I export Adobe Photoshop color table (.ACT) files as csv files?
Well, in photoshop you do not. But the file itself is just a list of 8bit binary rgb colors (according to adobe). So converting that to a csv should be pretty trivial to do with say python for example, you could also do it with jsx but its a bit more involved.
Here is a quick python example (quickly tested on the run):
#!/usr/bin/python # -*- coding: utf-8 -*- # act2csv.py quick script no warranties whatsoever import struct import csv DATA =  with open("test.act", "rb") as actFile: for _ in range(256): raw = actFile.read(3) color = struct.unpack("3B", raw) DATA.append(color) with open('test.csv', 'wb') as csvfile: csvWriter = csv.writer(csvfile) csvWriter.writerows(DATA)
