Data transfer from IPad Pro to PC

What kind of data?

Photos for instance can be transferred directly by accessing the iPad through Windows explorer as a camera.

Some Apps support iTunes File Sharing and files can be extracted from them through iTunes.

Use iTunes to share files between your computer and your iPhone, iPad, or iPod touch - Apple Support

Send it in an email. However, the data must be in a format that a program on the PC can read. That will only happen it the iPad app has a PC equivalent app from the same producer. Otherwise, your iPad app needs to export in a text format such as CSV or TSV.

It's also possible to move data back and forth using iTunes. See iOS- Syncing your data with iTunes.
