Can we convert a byte array of office file to pdf byte array in ASP.NET Core 6 MVC?

Question

I have an ASP.NET Core 6 MVC project. I want to convert my Office files to PDF. But the problem is I take my files as byte array and I must convert them to byte array pdf.

I tried to use gotenberg api but not worked. And also I asked this , but not worked too.

Note: I do not want to take any string path, I want to convert my byte array to PDF byte array.
