Format XML and convert to JSON for APIs

XML still powers config files, legacy APIs, and enterprise data exports, but modern web services demand JSON. When you're handed a wall of minified XML or need to bridge a traditional API with a JSON-based microservice, readability and format conversion become urgent. TextArray's browser-based tools let you pretty-print tangled XML, convert it to JSON on the fly, and handle YAML too—all without uploading a byte to the cloud.

Why XML formatting matters

Raw XML often arrives as a dense, single-line blob that defies reading. The XML formatter indents and colors it so you can actually trace the document structure: find the node you need, spot nesting errors, validate attribute placement, and debug schema mismatches in seconds instead of squinting at an unformatted wall of text. Well-formatted XML is the difference between a frustrating debugging session and a clear, immediate solution. For anyone working with configuration files, API responses, or data exports, this step alone saves hours of manual inspection.

Converting XML to JSON for modern APIs

JSON has become the lingua franca of web APIs and microservices, but you often receive or must work with data in XML—SOAP responses, configuration exports, data feeds from older systems, or EDI transactions. The XML to JSON converter translates the whole structure in one pass: attributes become object keys, nested elements become nested objects, text nodes become values, and arrays are handled automatically. Once converted, validate the output with the JSON formatter to ensure the structure is clean, properly quoted, and ready to send downstream to your microservices, webhooks, or data pipelines.

Privacy: your data stays in your browser

All TextArray tools run entirely in your browser using only JavaScript. Nothing is uploaded to a server, no account is required, and your XML, JSON, and YAML never leave your machine. After the page loads, you can disconnect your network and the tools continue to work offline—there are no API calls, no remote dependencies, no cloud processing whatsoever. This is especially important when handling sensitive XML that contains API keys, passwords, financial data, or personal information. You need absolute confidence that the data stays private and never transits the internet or sits on a third-party server.

Where YAML fits into the pipeline

YAML is another structured format you'll encounter, especially in Kubernetes manifests, Ansible playbooks, and modern CI/CD pipelines like GitHub Actions or GitLab CI. While YAML reads more naturally than JSON or XML—less punctuation, clearer hierarchy, fewer braces—it's not always what you need for downstream processing or API integration. The YAML to JSON converter lets you move between these formats seamlessly, so whether you're ingesting YAML config and need JSON for an API, converting legacy XML to YAML for a new pipeline, or transforming output from one tool to feed another, you're never stuck in the wrong format.

Common real-world use cases

Several workflows benefit from these tools working together:

• Debugging SOAP or XML-based REST APIs by formatting responses and converting them to JSON for inspection.
• Migrating legacy XML data into modern JSON-based systems, with validation at each step.
• Validating XML exports before conversion and import into a new platform or service.
• Converting configuration files between XML, JSON, and YAML as part of infrastructure upgrades or system migrations.
• Inspecting minified or poorly formatted XML without leaving your browser, uploading files, or signing into a tool.
• Bridging old and new systems when the old side speaks XML and the new side speaks JSON.

A practical workflow in minutes

Start with your XML source—paste it into the formatter to make it readable and verify the structure looks correct. Once you've confirmed it's valid, send it to the XML-to-JSON converter. Review the output in the JSON formatter to ensure the conversion preserved the structure correctly, then copy it to your application or API endpoint. If the result needs to be YAML for your deployment pipeline, use the YAML converter to move between formats as needed. The whole process happens instantly in your browser, with no dependencies, no uploads, and no account required—just load the page and go.
