I have searched online on how to import Mist APs via a CSV file but found nothing, could someone provide a link to documentation on how this can be  achieved?

There is no option for claiming AP's using a CSV file.  Unless you have a file with a list of claim codes, then just cut copy and paste the codes…

AP's can be claimed in bulk using an activation code from your sales order, one code will claim all devices (AP's, switch's, Edges, WAN edges) and activate your paid subscriptions with just one entry. Useful for anywhere from one to thousands of devices.

Claim codes can be used to claim a device individually, multiple claim codes can be used at the same time to claim multiple devices. Useful for anywhere from one to dozens of devices.

The QR code on an AP can be scanned and will claim the AP using the App. Useful for one at a time, especially during installation and mounting, take pictures, set height and orientation, name the AP and place it on the map. App instructions Mist AI Mobile App - Mist

Everything can always be done via API calls.

After the fact, all devices claimed can be exported to a CSV file by going to Organization -> Inventory and clicking on the download button in the upper right-hand corner.

You probably read the doc, but for reference Claiming APs - Mist

Hope this helps
