How to Convert XML to JSON in Batch

APIs, web services, and modern applications expect data in JSON. If your data is stored as XML — exported from databases, ERP systems, or legacy integrations — you need a reliable way to convert it. Total XML Converter reads XML files and transforms them into well-formed JSON, preserving the hierarchy of elements and attributes. It handles hundreds of files in a single batch run, entirely offline.

• Converts XML elements and attributes into JSON objects and arrays
• Processes an entire folder of XML files in one batch run
• Preserves nested structures — parent/child relationships remain intact
• Handles XML namespaces, CDATA sections, and mixed content
• Works 100% offline — no data leaves your computer
• Includes a 30-day free trial with full functionality

XML (eXtensible Markup Language) uses tags, attributes, and a tree structure to describe data. It supports schemas (XSD), namespaces, and comments. XML is widely used in enterprise integrations, SOAP web services, and configuration files. However, XML is verbose — tags add significant overhead, and parsing XML requires heavier libraries than JSON.

JSON (JavaScript Object Notation) represents data as key-value pairs, arrays, and nested objects. It is the default data format for REST APIs, NoSQL databases (MongoDB, CouchDB), and JavaScript-based applications. JSON is compact, human-readable, and parsed natively by every modern programming language.

When you convert XML to JSON, each XML element becomes a JSON object key. Attributes are mapped to keys (often prefixed with @). Repeated child elements become JSON arrays. The result is a lighter, API-ready representation of the same data.

How to Convert XML to JSON

• Step 1. Launch Total XML Converter. The left panel shows a folder tree for quick navigation.
• Step 2. Navigate to the folder containing your XML files. The file list in the center shows all XML files with name, size, and date.
• Step 3. Check the files you want to convert. Use Check All to select every XML file in the folder for batch conversion.
• Step 4. Click JSON in the format toolbar at the top of the window.
• Step 5. Set the destination folder and file naming pattern. Choose encoding (UTF-8 recommended) and formatting options.
• Step 6. Press Start. The converter processes each XML file and saves it as a JSON file in the output folder.

Each XML file produces a separate JSON file. Nested XML elements are mapped to nested JSON objects. Original XML files remain untouched.

Command-Line Conversion

Total XML Converter includes a command-line interface for scripting and automation:

XMLConverter.exe C:\Data\*.xml C:\Output\ -c JSON

This converts all XML files in the Data folder to JSON and saves them in the Output directory. Wrap the command in a .bat file or schedule it with Windows Task Scheduler for automated nightly conversions — ideal for ETL pipelines that feed JSON into APIs or NoSQL databases.

Why Use Total XML Converter?

Accurate structure mapping. Total XML Converter preserves the full hierarchy of XML elements in JSON output. Parent-child relationships, attributes, and repeated elements are mapped correctly without manual configuration.

Batch processing. Select hundreds of XML files and convert them all to JSON in a single run. Each file becomes a separate JSON document. No need to process files one at a time.

Handles complex XML. Namespaces, CDATA sections, mixed content, deeply nested elements — the converter handles them all. Even large XML feeds with thousands of nodes are processed quickly.

UTF-8 output. JSON files are saved in UTF-8 encoding by default — the standard for web APIs and modern applications. International characters are preserved correctly.

Offline and private. All conversion happens locally on your machine. XML data is never uploaded to any server. This matters when you work with sensitive business data, financial records, or personal information.

20+ output formats. Besides JSON, convert XML to CSV, XLSX, PDF, DOC, HTML, TXT, and more — all from the same program.

Total XML Converter Customer Reviews 2026

"We migrated 12,000 XML config files from a legacy SOAP service to a new REST backend. Total XML Converter handled the batch in under ten minutes. The JSON structure matched the XML hierarchy exactly — no manual fixes needed."

Stefan Gruber Backend Developer, Innova Systems GmbH

"Our ETL pipeline pulls XML feeds from government databases. I schedule the command-line converter to run nightly and output JSON for MongoDB import. It handles namespaces and CDATA without issues."

Rachel Nguyen Data Engineer

"Solid converter for day-to-day XML to JSON tasks. Batch mode works well, and the offline operation is important for our clients in regulated industries. Would be nice to have a JSON pretty-print option in the GUI."
