I want to develop a synchronized master player blueprint software. But I don't know the format of the blueprint-storage.dat file. If there is a way to know the file format, please let me know:)

Besides, my English is very bad. If you use the wrong words, please forgive me.

The format is the same as the save file format: quazi-random from an external perspective. It's a serialized version of the runtime data in a format the game knows how to read back later. There is no documentation and likely won't ever be since the format changes from game release to release as we need it to. The only way to know the format would be to have the source code and just use that to read it.

Sorry.

I've decoded the blueprint-storage.dat format -- the code is in GitHub: Factorio Blueprint Decode
You can use that code as a description of the format
