What Is the JSON to XML Converter?
The FinancialDataTools.com JSON to XML Converter is a free, browser-based tool that transforms JSON files into XML format. All processing runs entirely inside your browser tab — no file is ever transmitted to any server.
The converter is built for developers and system integrators who need to transform JSON array data into structured XML for APIs, configuration systems, or legacy application imports.
Try the JSON to XML Converter — runs entirely in your browser and never uploads your files.
Open the Converter →About the JSON Input Format
The converter accepts .json files. The JSON must be an array of objects at the top level. Each object in the array becomes one XML record element. The keys from the objects become child element tag names, and the values become element text content.
About the XML Output Format
The output is a well-formed XML document with a <records> root element. Each object in the JSON array becomes a <record> child element. Each key-value pair becomes a child element of the record. Special characters in values are properly escaped. The output is indented for readability.
The Toolbar
The toolbar provides all primary actions. Use Open to browse for your JSON file, or drag and drop the file onto the source panel. Once a file is loaded, click Convert to XML to generate the output. Click Export XML to download the result. The Reset button clears all state for a new conversion.
Source (JSON) Panel
The left panel shows your loaded JSON data as a table preview. Column headers are derived from the object keys. For large files, the preview is capped at 500 rows. The full dataset is always converted regardless of the preview cap.
Output (XML) Panel
The right panel displays the converted XML output as formatted text. Before conversion it shows a placeholder. After clicking Convert to XML, the panel renders the full XML document. The panel is scrollable for any file size.
Output File Naming
The downloaded file is named to match your input file — only the extension is changed to .xml. This keeps your file set organised without requiring any renaming.
Privacy & Security
The JSON to XML Converter is built privacy-first. Your file is parsed and converted entirely inside your browser tab using JavaScript — no file content is ever transmitted to any server. This makes the converter appropriate for sensitive data.
Closing the browser tab clears all data from memory. No data is written to localStorage or any persistent browser storage.
Use Cases
Converting API response data to XML for legacy system imports, transforming JSON datasets to XML for configuration files, preparing JSON data for use with XML-based processing pipelines, and sharing structured data with systems that require XML.
