What Is the XML to JSON Converter?
The FinancialDataTools.com XML to JSON Converter is a free, browser-based tool that transforms XML files into JSON format. All processing runs entirely inside your browser tab — no file is ever transmitted to any server.
The converter is built for developers who need to extract structured data from flat XML files and use it in APIs, web applications, or modern data pipelines that consume JSON.
Try the XML to JSON Converter — runs entirely in your browser and never uploads your files.
Open the Converter →About the XML Input Format
The converter accepts .xml files. The XML must have a root element containing repeating child elements (rows). Each child element's children become the properties of the corresponding JSON object. All unique child element tag names are collected across all row elements to form the complete property set.
About the JSON Output Format
The output is a JSON array of objects. Each XML row element becomes one object. The tag names of the row's children become property keys, and the text content of each child becomes the property value. Missing child elements produce a null value. The output is pretty-printed with two-space indentation.
The Toolbar
The toolbar provides all primary actions. Use Open to browse for your XML file, or drag and drop the file onto the source panel. Once a file is loaded, click Convert to JSON to generate the output. Click Export JSON to download the result. The Reset button clears all state for a new conversion.
Source (XML) Panel
The left panel shows your loaded XML data as a table preview. Column headers are the tag names of the child elements. For large files, the preview is capped at 500 rows. The full dataset is always converted regardless of the preview cap.
Output (JSON) Panel
The right panel displays the converted JSON output as formatted text. Before conversion it shows a placeholder. After clicking Convert to JSON, the panel renders the full output. 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 .json. This keeps your file set organised without requiring any renaming.
Privacy & Security
The XML to JSON 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 XML data exports to JSON for modern API consumption, transforming legacy XML data feeds for use in JavaScript applications, preparing XML datasets for JSON-based ETL pipelines, and sharing structured data with systems that require JSON format.
