## Overview

The Avro Converter is a specialized utility designed to seamlessly encode JSON data into the Avro binary serialization format or decode existing Avro data back into readable formats. With support for custom Avro schemas, this tool ensures data integrity and compatibility for developers working with Apache Avro in big data pipelines and messaging systems.

## Inputs

- **Input Data** (textarea): Enter JSON data to encode or Avro data to decode...
- **Operation** (select)
- **Output Format** (select)
- **Avro Schema (Optional)** (textarea): Enter Avro schema JSON (optional)...

## When to use

- When you need to serialize JSON objects into Avro binary format for storage or transmission.
- When you need to inspect or debug binary Avro data by decoding it back into a human-readable format.
- When you are developing data schemas and need to verify that your JSON payloads conform to specific Avro definitions.

## How it works

- Select your desired operation: 'Encode' to convert JSON to Avro, or 'Decode' to convert Avro to JSON.
- Paste your input data into the primary text area.
- Optionally provide your Avro schema in the schema field to ensure accurate parsing and validation.
- Choose your preferred output format (Hexadecimal or Base64) and execute the conversion.

## Use cases

- Preparing JSON payloads for ingestion into Apache Kafka topics using Avro serialization.
- Debugging binary data captured from network logs or message queues.
- Validating that application-generated JSON objects match established Avro schema definitions.

## Frequently asked questions

### What is Avro format?

Avro is a row-oriented remote procedure call and data serialization framework that uses JSON for defining data types and protocols.

### Do I need to provide a schema?

While the tool can attempt to process data without one, providing an Avro schema is highly recommended for accurate encoding and decoding.

### Can I convert binary Avro files directly?

This tool processes text-based representations of binary data, such as Hex or Base64 strings.

### What output formats are supported?

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

### Is my data stored on your servers?

No, all encoding and decoding operations are performed locally in your browser for your privacy and security.
