How to transfer ipad keynote to laptop?

I bought an ipad and I don't know how to use Keynote to transfer my presentations to a laptop. Because I want to present it at school with a projector.

The Apple cosmos is also fairly isolated there.

I would suggest saving it in a PC-compatible format and sending it by email.

What is preventing you from using the iPad on the projector via Bluetooth or WLAN?

I do not know if it works

What operating system is on the laptop and how does the laptop connect to the projector at school?

Believe with a USB connection

An iPad can also be connected via USB.

Then you should first inquire how the projector is connected, whether a radio connection is possible or a driver is necessary, and then provide the necessary data.
