About Merge XML Files Online – Combine Multiple XML Files
Combine multiple valid XML documents without manually removing XML declarations or copying individual records.
Choose matching-root mode for related datasets or wrapper mode when the source documents use different root elements.
Input is processed locally in your browser and is not sent to Navorika.
How the calculation works
Matching-root merge
The tool retains the first document root and appends the child nodes from every document in the selected order.
Wrapper-root merge
Each complete source root is placed inside one new user-named wrapper element.
Output validation
The completed output is parsed again before download to confirm that it remains a well-formed XML document.
How to use this tool
- 1Add between 2 and 500 XML files with a combined size of no more than 10 MB.
- 2Reorder the files to control the sequence of the merged content.
- 3Choose matching-root mode or wrapper-root mode.
- 4Merge, review the preview, and download the validated XML file.
Understanding the result
Matching-root mode combines child records and requires every document to use the same root name and namespace.
Wrapper mode preserves each source root as a separate child beneath the new wrapper element.
The downloaded file contains the complete result even when the on-screen preview is shortened.
Important limitations
- The maximum combined input size is 10 MB and the maximum number of files is 500.
- Matching-root mode does not attempt to reconcile incompatible schemas, root attributes, namespace designs, or conflicting business records.
- The tool validates XML structure but cannot determine whether the merged data satisfies a private XSD or business system requirement.
- DTD-based and external-entity-dependent documents may not be suitable for browser-based merging.

Frequently asked questions
Can I merge XML files with different root elements?
Yes. Select wrapper mode and provide a valid name for the new common root element.
Does the tool remove duplicate records?
No. Records are retained in file order because XML does not have a universal field that identifies duplicates.
Are my XML files uploaded?
No. Reading, validation, merging, preview generation and download all run locally in your browser.
How many XML files can I combine?
You can combine up to 500 files as long as their total selected size does not exceed 10 MB.
