Free Data File Converters: CSV to JSON, JSON to CSV, XML and YAML

Convert data files between formats

APIs, feeds and exports do not always come in the format your code or spreadsheet expects. These free converters change the format in your browser, so the data you paste is not uploaded.

XML to JSON

The XML to JSON converter turns XML into JSON and lets you choose how attributes, arrays, CDATA and namespaces are handled. Paste the XML or open a file, check the result and copy or download it.

For regular expressions and IDs see the developer tools. To convert images rather than data, use the image converters, and for PDFs try WoowPDF.

Tips

• Check how repeated XML elements become arrays, so a single item and many items give the same JSON shape.
• Decide on a prefix for attributes before you build code around the output, and keep it the same everywhere.
• Validate the JSON in your own code after converting a large or unusual file.
