## Overview

The CBOR Converter is a streamlined utility designed to encode JSON data into Concise Binary Object Representation (CBOR) or decode binary CBOR data back into readable formats. It simplifies the serialization process for developers working with IoT protocols, network communications, and binary data storage.

## Inputs

- **Input Data** (textarea): Enter JSON data to encode or CBOR data to decode...
- **Operation** (select)
- **Output Format** (select)

## When to use

- When you need to serialize JSON objects into a compact binary format for efficient network transmission.
- When debugging binary payloads received from IoT devices or embedded systems that utilize CBOR.
- When you need to convert binary CBOR data into a human-readable format for verification or documentation.

## How it works

- Paste your JSON or binary data into the input field.
- Select the operation mode: 'Encode' to create CBOR or 'Decode' to revert to JSON.
- Choose your preferred output format, such as Hexadecimal or Base64, to suit your integration requirements.
- Click the convert button to generate the processed output instantly.

## Use cases

- Optimizing data payloads for low-bandwidth IoT device communication.
- Inspecting binary data packets during API development and debugging.
- Converting configuration files into compact binary formats for embedded storage.

## Frequently asked questions

### What is CBOR?

CBOR (Concise Binary Object Representation) is a binary data serialization format designed for small code size and small message size, often used in IoT and constrained environments.

### Can I convert CBOR to JSON?

Yes, select the 'Decode' operation to transform binary CBOR data back into a standard JSON structure.

### What output formats are supported?

The tool supports outputting the resulting binary data in either Hexadecimal or Base64 strings.

### Is this tool suitable for large datasets?

The tool is optimized for standard data payloads. For extremely large files, ensure your browser has sufficient memory to process the serialization.

### Does this tool store my data?

No, all conversion processes occur locally in your browser. Your data is not uploaded to or stored on any server.
