Free JSON, XML & SOAP Formatter with Syntax Highlighting

Published: November 4, 2025 · 8 min read · Category: Developer Tools

Instantly beautify minified JSON, XML, and SOAP data. Format, highlight, and copy with one click - no installation required.

The Problem with Minified Data

You receive an API response that looks like this:

{"booking":{"property_id":"1620436","property_name":"Hotel Example","booking_date":"2026-01-29","status":"Confirmed","customer":{"name":"John","email":"john@example.com"}}}

Good luck reading that! Or even worse, XML:

<booking property_id="1620436" property_name="Hotel" status="Confirmed"><customer name="John" email="john@example.com"/></booking>

The Solution: Professional-Grade Formatter

GeoSyncX's Formatter Studio transforms messy data into readable, properly indented output.

Key Features

1. Auto-Detection

Paste any data and the formatter automatically detects whether it's JSON, XML, or SOAP.

2. Professional XML Formatting

Tags with many attributes are formatted with each attribute on its own line:

<booking
    property_id="1620436"
    property_name="Hotel Example"
    booking_date="2026-01-29"
    status="Confirmed">
  <customer
      name="John"
      email="john@example.com"/>
</booking>

This makes it easy to scan key-value pairs, compare data, and debug API responses.

3. Syntax Highlighting

Color-coded output makes it easy to distinguish:

• Keys and attributes
• String values
• Numbers and booleans
• XML tags

4. Escape/Unescape Strings

Two additional modes for handling escape characters:

• Add Escape Characters: Convert newlines, quotes, tabs to \n, \", \t
• Remove Escape Characters: Convert \n, \", \t back to actual characters

5. One-Click Copy

Copy the formatted output to clipboard instantly.

Supported Formats

    {"id": 2, "total": 149.99}
  ]
}
