How to Format MessagePack - Step by Step Guide

Step 1

Input Your MessagePack Data

Let's get your MessagePack data into the formatter! You have several convenient options:

•
Paste directly: Copy your MessagePack data in Base64 or Hex format from APIs or binary tools
•
Upload a file: Click "Upload" to select a .msgpack or .bin file from your computer
•
Try the sample: Click "Sample" to load example data and see how the formatter works

Example: MessagePack Binary Data (Base64)

Here's what encoded MessagePack looks like:

Step 2

Automatic Decoding & Formatting

The magic happens instantly! As soon as you input MessagePack, the formatter automatically:

•
Decodes binary data: Converts MessagePack Base64 or Hex to readable JSON format
•
Adds proper indentation: Makes nested objects and arrays easy to read
•
Syntax highlighting: Color-codes different elements for better readability

Example: Decoded and Formatted Output

The MessagePack data decoded to readable JSON:

{
  "name": "John",
  "age": 30,
  "active": true
}
Step 3

Choose Format Options

Customize your output based on your needs! The formatter gives you control over how your decoded JSON appears:

•
Pretty format: Default beautified JSON with proper indentation (2 spaces)
•
Minify option: Click "Minify" to compress JSON into a single line for production use
•
Syntax highlighting: Color-coded elements make it easy to spot different data types
Step 4

Export Your Formatted JSON

Get your perfectly formatted JSON ready for use! Multiple export options make it easy to integrate into your workflow:

•
Copy to clipboard: One-click copying for quick pasting into your code editor or application
•
Download as file: Save as a .json file for later use or sharing with your team
•
Real-time validation: Green checkmark confirms your MessagePack is valid and decoded successfully

Frequently Asked Questions

How do I format MessagePack binary data?

Simply paste your MessagePack data (in Base64 or Hex format) into the formatter. The tool automatically decodes the binary data and displays it as beautifully formatted JSON with proper indentation, line breaks, and syntax highlighting.

Can I format and minify MessagePack in the same tool?

Yes! The formatter decodes MessagePack and displays it in "Pretty" mode for readable formatting, or click "Minify" for compressed single-line JSON. Perfect for development (pretty) and production (minified) use cases.

What MessagePack formats are supported?

The formatter supports Base64-encoded MessagePack (most common for web APIs) and hexadecimal format. Simply select the format using the radio buttons and paste your data.

Can I format large MessagePack files?

Absolutely! The formatter handles large MessagePack files efficiently. The tool processes them in chunks to maintain smooth performance while preserving perfect formatting. You can also use MessagePack Validator to validate without formatting.

Why use MessagePack instead of JSON?

MessagePack is 20-30% smaller than JSON and faster to parse, making it ideal for high-performance APIs and microservices. Use this formatter to decode and inspect MessagePack data during development.

Is the MessagePack formatter completely free?

Yes, totally free with no limitations on file size, usage frequency, or features. No registration required, and you can format unlimited MessagePack files with full syntax highlighting and validation.
