Om dette verktøyet

This tool converts JSON inputs into XML representations suitable for data interchange, configuration management, and system integrations. It targets developers, data engineers, and API teams needing reliable XML payloads from JSON sources.
Conceptually, the tool parses JSON into a hierarchical data model, then serializes it to XML by mapping object keys to elements, arrays to repeated child elements, and primitive values to text content or attributes. It supports nested structures, whitespace control, and optional root naming.
Key features include deterministic tag naming, configurable root element, array handling options, and pretty-printed output. It enforces XML well-formedness, preserves data types where possible, and validates against sample schemas when provided. It runs entirely in-browser or server-side, with no external dependencies.
Use cases include data migration, API responses to XML consumers, or integration with legacy systems. Unique value lies in clear mapping rules, error reporting, and consistent output across complex JSON structures, enabling repeatable, auditable data transformations.

Frequently Asked Questions

Finn raske svar

What input formats are supported?

The tool accepts plain JSON text in either minified or pretty-printed form. It validates JSON syntax and reports precise error positions for malformed input. Nested structures are preserved in the resulting XML hierarchy.

Can I customize the XML root name?

Yes. The root_name option lets you set the XML root element. If not provided, a default root element is used. This aids compatibility with schemas or downstream services that expect a specific root.

How are JSON arrays represented in XML?

Arrays are expanded into repeated child elements under the array parent. An optional wrapper element may be used to group items, depending on configuration. This ensures predictable, repeatable XML structures.

Is the tool free to use?

Yes, it is a free online tool. No sign-up is required for standard conversions. Advanced options may be available within the session but do not require payment.
