CBOR EDN Editor

CBOR EDN Editor allows you to open, view, and edit binary CBOR files as human-readable Extended Diagnostic Notation (EDN) directly in VS Code.

Open .cbor files instantly in a split-view editor.

Core Features

Live Side-by-Side Hex Editing

Watch your binary data change as you type. The integrated view shows the exact Hex representation of your CBOR structure in real-time. No manual compilation needed.

Live syntax error checking & Quick Fixes

Powered by a custom parser, the editor catches syntax errors instantly, underlines them in red, and offers Quick Fix suggestions when available.

Export Options

• When a CBOR file is opened, it can be exported as EDN.
• When an EDN file is opened, it can be exported as CBOR.

Advanced Capabilities

• Smart Formatting
• Cross-selection highlighting between EDN and binary bytes
• One-click data export for sharing via cbor.me
• Hover support for Lexer/Parser Errors and tags

Known Issues / Limitations

• Syntax Checking: The validation is currently experimental. It may not catch all edge cases or complex nested structures yet.
• Large Files: Very large files might cause performance problems during live updates.
• Comments in CBOR: Since CBOR is a binary format, comments in .cbor files are discarded when saving. Comments in .edn files are preserved.
