How to organize data export from 1C?

Question

.NET

Greetings,
I am now making some kind of integrator in C #, which should receive data from 1C. Since I have never been one-stop, a number of questions arose:
- What formats can be exported from 1C - CSV, XML, JSON? Do you need support for all three formats or is there some main one?
- In what form can data be uploaded from 1C for exchange in an external system? Through FTP (a file server from which files will be read at a certain frequency) or is it possible to organize a service that issues a data stream?
The question is rather chaotic, but this is because I don’t even have a close idea of ​​\u200b\u200bwhat 1C is and how data storage is organized there.
