CBOR Inspector & Converter
CBOR Inspector & Converter: Decodes Concise Binary Object Representation (CBOR) major types and emits JSON representation.
About this cbor inspector & converter
CBOR Inspector & Converter — browser-based utility.
How this tool works
Implements client-side CBOR Inspector & Converter operations. Decodes Concise Binary Object Representation (CBOR) major types and emits JSON representation specifically designed for an embedded systems engineer inspects a cbor (rfc 8949) binary packet received from a ble peripheral device.
- Lexical Scanning: Scans the input stream character by character, identifying string literals, escape sequences, numbers, and structural delimiters without converting numeric tokens to native floats.
- Syntax Validation & Invariant Checking: Enforces RFC 8259 syntax constraints, verifying matching braces, balanced brackets, unescaped control characters, and duplicate key collision detection.
- AST Assembly & Structural Transformation: Constructs an immutable memory tree representation, applying structural indentation, key alphabetical sorting, or schema-mapped transposition.
- Serialization & Diagnostic Formatting: Emits formatted, color-coded, or minified text with byte-length calculation, structural nesting depth metrics, and RFC-compliant line terminators.
Worked example
Scenario: Decode a definite-length CBOR map from hexadecimal.
Sample input:
Processing: Decode one supported top-level value and render JSON.
Illustrative output:
Limits and verification
Fails with descriptive line and column diagnostics when encountering unquoted object keys, single-quoted strings (in strict JSON mode), trailing commas (in RFC 8259 mode), or unescaped ASCII control codes (0x00 through 0x1F). Objects with circular self-references are intercepted by identity tracking sets before serialization begins. Input size is bounded by browser memory (typically 50-100 MB).
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

How to use it
- Enter, paste, or select your input data into the CBOR Inspector & Converter workspace controls.
- Review available parameter fields, units, formats, or options configured for your task.
- Click the action button or observe immediate live calculations rendered in your browser runtime.
- Inspect the resulting output and any diagnostic messages, then copy or download the result if needed.
Frequently asked questions
What CBOR value does the supported example decode?+
The hexadecimal bytes `a1 61 61 64 43 5a 4f 41` decode to the definite-length map `{ "a": "CZOA" }`, which the page serializes as JSON.
How should CBOR bytes be entered?+
Provide hexadecimal byte text, with the supported separators, and run locally. The decoder reads one top-level CBOR value before JSON serialization.
What decoder limits matter for CBOR?+
It rejects malformed byte text, truncation, indefinite-length items, unsupported simple values, invalid UTF-8, and trailing bytes. It implements a definite-length subset rather than every CBOR extension.
Does the page send entered CBOR bytes?+
The browser run decodes the entered hexadecimal text and renders JSON in the page. Its tool request log contains no request carrying the submitted CBOR bytes; normal page resources are a separate surface.
