PS i dont see how i could add colorgroups clearly in the CSV without changing the formatting to much. Basically adding the gradient is already changing that. If i recall correct, the colorgroups are not exposed to script. ExtendScript doesnt know if a color is inside a color group

Understood. You’ve done a masterful job.

That script to convert colors to a gradient would be cool. Is it somewhere I can download?

@fuzenco
Actually swatchgroups are exposed. I see what I can do about that. I would need to check if can test if a swath or spot is a child of a search group, than it would be possible
..

I did found it, it was made by someone else. It only does CMYK now. I'll need to update it so it will do all kinds of document color modes

@schroef . Tested it. Gradient export works perfect. However…

I do see a bug in the script, though. After creating my gradients and properly exporting, if I add additional standard swatches (in my case 2 colors in a color group/folder), those two new colors do not get exported when the same file name is used for the CSV. In my case, I had to duplicate the file and rename it. Running the script did include the two new swatches this time around.

Here’s the file I used: http://fuzen.co/dropbox/test2.ai.zip

I just tested your file and it works just fine with v002. I opened your test doc and add a new swatchgroup and added 3 extra colors. I had the csv export from earlier open in Visual Studio Code and after a new export, those 3 colors where added.

You do have v002 right?

I do but it must have been an intermittent bug. 3x I tried to overwrite that initial file. The new file was saved (which overwrote the test2 file), but the new colors were not being added. However, today everything seems to be working fine although I had 002 all along. So disregard this report and if it pops up again, I’ll notify you. Thanks.
