Using Copy/Paste is often preferred to import/export, since you have more fine-grained control over the data transfer process.

Adobe Illustrator

When pasting in LED Wizard, if there's a PDF format in the clipboard (which is what AI creates with Copy), it will be the default format pasted when you selected Edit | Paste in LED Wizard. This format is the same as importing from a PDF file, with the added benefit of being to select just the objects you want in AI.

Corel Draw

With Corel Draw, we support full copy and paste, including all special LED elements, along with the statistics.

When using Edit | Paste in Corel Draw, the default format will be a bitmap, so you need to select Edit | Paste Special and select Picture (Enhanced Metafile) in order to transfer the full vector data (and text) from LED Wizard
