If your program is not listed here
Look for AAF, sometimes called the astrological exchange format, in its export menu. Failing that, look for any export at all that produces a spreadsheet or a text file, since those two cover almost everything. If you are not sure what you are looking at, send the file to support@arcusastrology.com and we will tell you whether Arcus can read it, or teach Arcus to read it.
Some programs keep your charts and offer no way out. If yours does, the file you originally brought into it is the one to use here.
