See, for example:

- [How to read binary file in Julia? - Stack Overflow](https://stackoverflow.com/questions/59991708/how-to-read-binary-file-in-julia)
- [How do I read a binary file back into an Array?](https://discourse.julialang.org/t/how-do-i-read-a-binary-file-back-into-an-array/28454)
- [Read binary data of arbitrary dims and type](https://discourse.julialang.org/t/read-binary-data-of-arbitrary-dims-and-type/28560)

All of these appeared in the first page of Google results for “read binary file Julia”, and they all point to the same function: [`read!`](https://docs.julialang.org/en/v1/base/io-network/#Base.read!).

(Of course, this assumes that your “binary data” just consists of raw arrays written directly to a file, as opposed to a more structured binary format like HDF5.jl.)
