About this utility
How to use Binary Serialization Inspector
Detect and decode MessagePack, CBOR, or BSON into a bounded, navigable structure without executing decoded values.
What to provide
Drop one local binary serialization file. Auto detection tries the three supported decoders in a deterministic order.
- Choose or drag the local file into the clearly labeled drop area.
- Choose the options that match your intended result.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
Detected format, byte length, and a JSON-safe structured representation.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- Everything is processed in this browser tab. Input, filenames, keys, and output are never uploaded or saved. Binary byte strings are represented as bounded hex previews, and extension/tag semantics remain format-specific.
