import chart data from Excel or CSV
Need to be able to import data from an Excel (or at least a CSV) file, to create chart with Charting tool. Rather antiquated to have to copy/paste to get data for a chart. (In more than 30 years of using AI, I've NEVER been given a data file in TXT format--the only option currently available to import graph data.)
Check out Datylon Graph for Illustrator extension. Maybe this solves the data importing issues you are facing?(and maybe even some more!)
From Excel, do File > Save As unicode text file. WIth a .csv, change the file extension to .txt. They are the same thing.
