you want to convert a file to Google Sheets, that likely requires several different microservices working in tandem to handle your request.

Because file conversion is pure (in the functional programming sense). It produces an output based solely on the given input, without side effects.

If you have to implement a pure function by splitting it across multiple services, there is something very, very wrong with your software architecture.
