Well-formed XML generation from JSON

Generates valid XML with XML declaration (<?xml version="1.0" encoding="UTF-8"?>), proper attribute formatting, and clean tag indentation from arbitrary JSON structures.

What to expect and limitations

Maximum file size: 10 MiB. JSON keys must be valid XML tag names or will be normalized. Maximum nesting depth: 25 levels.

Private browser processing

Your data is parsed, validated, and converted entirely in your web browser. File content is never transmitted over the internet to FileNimble servers. All calculations run in your local browser memory. Clearing the tool or leaving the page releases application references; this is not a guarantee of secure memory erasure. Saved downloads remain on your device.

Formula injection prevention is applied by default when generating CSV output to help protect against remote command execution and exfiltration attacks when opening files in spreadsheet applications such as Microsoft Excel and Google Sheets.

Frequently Asked Questions

What root element is used?

If your JSON does not have a single top-level key, elements are wrapped in a standard <root> container.

How are JSON arrays represented in XML?

Array elements are wrapped in repeated <item> child tags under their parent container.
