Solution needed to export Custom Audience from Facebook

Hello,

I have build a custom audience by putting a facebook retargeting pixel on my website.

I need to export the list to add to other facebook accounts I use.

I do not want to share my ad account with other facebook users.

What is the tool needed to extract the UID's from this Custom audience to a CSV file or TXT file.

Please get back to me!

Bump .. still looking for a solution.
Please help!

Have you found the solution? Is it possible at all?

not sure if thats possible :s
